Long-term follow-up of unoperated macular holes.

OBJECTIVE: To investigate the anatomic and visual acuity outcomes among patients with unoperated macular holes and at least 5 years of follow-up. DESIGN: Retrospective, noncomparative case series from an institutional practice setting. PARTICIPANTS: All patients with unoperated full-thickness macular holes evaluated at Bascom Palmer Eye Institute between January 1, 1968 and December 31, 1993 and observed for at least 5 years. METHODS: Demographic and clinical data were abstracted from patients' medical records and ophthalmologic photography records. For patients with bilateral macular holes, only one eye was included. MAIN OUTCOME MEASURES: Visual acuity and clinical features on initial examination, at 5 years, and at final follow-up. RESULTS: The study included 65 eyes of 65 patients with a median age of 65 years (range, 52-85 years) and a median follow-up of 9.3 years (range, 5-29 years). On initial examination at Bascom Palmer Eye Institute, the macular hole was stage 2 in 15 eyes (24%), stage 3 in 23 eyes (37%), and stage 4 in 25 eyes (40%). At final follow-up, the macular hole was stage 3 in 10 eyes (16%) and stage 4 in 53 eyes (84%). Visual acuity was 20/200 or worse in 35 eyes (54%) on initial examination, in 43 eyes (74%) at 5 years, and in 53 eyes (82%) at final follow-up. Poorer visual acuity on initial examination was a significant predictor of poorer final vision (P < 0.01). Other accompanying clinical features such as the presence of operculum, posterior vitreous detachment, and epiretinal membrane were not significantly associated with final vision. Throughout follow-up, there was a redistribution and reduced number of yellow nodular opacities at the level of the retinal pigment epithelium at the base of the macular holes and the development of retinal pigment epithelial atrophy around the macular holes. CONCLUSIONS: Long-term follow-up of unoperated macular holes demonstrates progression in hole size and stage, vision loss which generally stabilizes at the 20/200 to 20/400 level, a redistribution and reduced number of yellow nodular opacities at the level of the retinal pigment epithelium, and the development of retinal pigment epithelial atrophy surrounding the macular hole, resulting in a "bull's-eye" macular appearance.

Surgery for idiopathic macular holes associated with extensive subretinal fluid.

PURPOSE: To study the baseline characteristics and outcomes of surgery for idiopathic macular holes associated with localized macular detachment. METHODS: In this case-control study, eight consecutive patients with idiopathic macular hole associated with localized macular detachment (cases) and 30 randomly selected patients with idiopathic macular hole not associated with macular detachment underwent macular hole surgery. RESULTS: The mean age (62.1 versus 68.2 years; P = 0.086), mean refractive error (-0.13 versus +0.23 diopters; P = 0.68), average duration of symptoms (5.9 versus 4.6 months; P = 0.47), and macular hole stage (P = 0.43) were similar in the cases and controls. The baseline visual acuity ranged from 20/50-20/80 (1 [13%] versus 1 [3%]) to 20/100-20/200 (2 [25%] versus 24 [80.0%]) to < 20/200 (5 [63%] versus 5 [17%]) (P = 0.10). Single-operation anatomic success was achieved in 2 (25%) cases and 24 (80%) controls (P = 0.007). Visual acuity 3 months after the last macular hole surgery was worse in cases compared to controls: > or = 20/40 in 0 versus 6 (20%), 20/50-20/80 in 1 (13%) versus 13 (43%), 20/100-20/200 in 4 (50%) versus 10 (33%), and < 20/200 in 3 (38%) versus 1 (3%) (P = 0.003). The mean improvement in visual acuity was 0.2 logMAR units in cases versus 0.4 logMAR units in controls (P = 0.054). CONCLUSIONS: Surgical outcomes for idiopathic macular hole associated with a localized macular detachment compare poorly with the outcomes for macular hole not associated with extensive surrounding subretinal fluid.

Evaluation of efficacy and complications: primary pediatric orbital implants after enucleation.

BACKGROUND: Orbital implants are used routinely in pediatric patients at the time of enucleation. Complications, such as exposure, ptosis, and infection, may occur after implantation. Controversy continues regarding the rate of complications with newer implants in the pediatric population. OBJECTIVE: To examine the effects of orbital implants on children whose eyes have been enucleated. METHODS: Records of orbital implantation after enucleation performed by 5 surgeons on 120 pediatric patients (123 eyes) over a 10.5-year period were reviewed retrospectively. Demographic data, ocular diagnosis, prior ophthalmic surgery, implant characteristics, and postoperative complications were described using a standardized format for all patients, with a minimum of 6 months of follow-up (mean, 3 years). RESULTS: Complications were observed in 7 eyes (5.7%). Implant exposure (1 [0.8%]), implant extrusion (0 [0%), and implant migration (3 [2.4%) were rare. One hundred eighteen eyes (96%) had good cosmesis and 120 (98%) had good motility. CONCLUSIONS: Orbital implantation after enucleation is successful in the pediatric population. Complications are minimal. Hydroxyapatite implants were not associated with unacceptable complications in this pediatric population.

Combined pars plana vitrectomy and glaucoma drainage implant placement for refractory glaucoma.

PURPOSE: To report visual acuity and intraocular pressure outcomes among patients who have undergone combined pars plana vitrectomy and placement of a glaucoma drainage implant. METHODS: The medical records of all patients who underwent combined pars plana vitrectomy and placement of a glaucoma drainage implant at the Bascom Palmer Eye Institute by one of the authors between January 1, 1990, and February 28, 1998, were reviewed. Forty patients (40 eyes) were identified, including 14 patients with neovascular glaucoma secondary to proliferative diabetic retinopathy or central retinal vein occlusion, 15 patients with other posterior segment disease, seven patients with secondary angle-closure glaucoma, and four patients with aphakia with ruptured anterior hyaloid face. Main outcome measures included visual acuity and intraocular pressure at 1 year postoperatively. RESULTS: At 1 year postoperatively, 31 (77.5%) of 40 patients had stable or improved visual acuity; three eyes (7. 5%) had a final visual acuity of no light perception and three additional eyes (7.5%) were enucleated (because of chronic pain in two eyes and endophthalmitis in one eye). Mean preoperative intraocular pressure was 34 mm Hg and the median number of preoperative antiglaucoma medications was two. At 1 year postoperatively, mean intraocular pressure was 13 mm Hg and the median number of antiglaucoma medications was zero. Twenty-two patients (55.0%) achieved an intraocular pressure greater than 5 mm Hg and less than or equal to 21 mm Hg without antiglaucoma medication, and an additional seven patients (17.5%) achieved this level of intraocular pressure control with medication. Only one patient (2.5%) underwent further glaucoma surgery for uncontrolled intraocular pressure. CONCLUSIONS: Although combined pars plana vitrectomy and placement of a glaucoma drainage implant is often a successful management option in selected patients with refractory glaucoma, visual outcome may be poor because of severe underlying ocular disease and postoperative complications.

Scleral rupture during retinal detachment surgery: risk factors, management options, and outcomes.

OBJECTIVE: To evaluate the potential risk factors, management strategies, and outcomes of scleral rupture during retinal detachment (RD) surgery. DESIGN: Case-control study. PARTICIPANTS AND CONTROLS: Fourteen consecutive patients with scleral rupture during RD surgery (cases) and 65 consecutive patients who underwent RD surgery without scleral rupture (controls). INTERVENTION: Demographic and clinical data were abstracted from patients' medical records. OUTCOME MEASURES: Visual acuity and retinal attachment status at the last examination. RESULTS: Significant risk factors for scleral rupture during RD surgery were reoperation after failed RD surgery (71 % vs. 32%), and pre-existing scleral pathologic condition (29% vs. none). The site of rupture was in the bed of a previously placed scleral buckle in all patients with a previous buckling surgery. Repair of the rupture included scleral sutures in eight (57%), scleral patch graft in four (29%), and placement of a scleral buckle over the site in two (14%) eyes. Eleven (79%) underwent vitrectomy with retinal tamponade by gas (n = 4) or silicone oil (n = 7). Complications observed postoperatively included vitreoretinal incarceration (n = 3), vitreous hemorrhage (n = 2), suprachoroidal hemorrhage (n = 2) and subretinal hemorrhage (n = 3). In the 14 eyes with scleral rupture, the final visual acuity was > or =20/40 in 1 (7%), 20/50 to 20/200 in 5 (36%), and <20/200 in 8 (57%). Ten (71 %) had proliferative vitreoretinopathy develop. The retina was attached in 7 (50%), 6 (43%) had localized peripheral detachment, and 1 had a total retinal detachment. The vision improved in 4 (29%), was unchanged in 5 (36%), and was worse than before surgery in 5 (36%). In the 65 controls, the visual acuity at the time of the last examination was > or =20/40 in 26 (40%), 20/50 to 20/200 in 21 (32%), and <20/200 in 18 (28%). Sixty three (97%) patients had complete retinal reattachment, 1 (2%) had a localized peripheral RD, and 1 (2%) had an RD involving the posterior pole. After surgery, the vision improved in 45 (69%), was unchanged in 15 (23%), and was worse in 5 (8%) of the control eyes. The visual and anatomic outcomes of the eyes with scleral rupture were significantly worse than in the control group (P = 0.002 and P < 0.001, respectively). CONCLUSIONS: Risk factors associated with intraoperative scleral rupture include reoperation for failed RD surgery and pre-existing scleral pathology. Although this complication may be compatible with a good visual outcome in some patients, a high incidence of persistent or recurrent RD with proliferative vitreoretinopathy worsens the visual outcome for most patients with this complication.

Quality of life of low-vision patients and the impact of low-vision services.

PURPOSE: To investigate the functional status and quality of life of patients at a low-vision clinic and to evaluate the impact of low-vision services. METHODS: Interviews, including the Medical Outcomes Study 36-Item Short Form (SF-36), the Visual Function-14 (VF-14), and the 51-item Field Test Version of the National Eye Institute Visual Functioning Questionnaire (NEI-VFQ), were administered to 156 consecutive patients 1 week before and 3 months after their low-vision clinic visit. RESULTS: Low-vision patients scored lower (P < .001) in physical functioning and role limitations caused by physical and emotional health problems than published SF-36 scores of the age-appropriate United States normal population, patients with congestive heart failure, and clinically depressed patients. Low-vision services were associated with improvement in the subjective functional status of 150 patients (98.7%) and were rated "very useful" by 82 (53.9%) patients. The SF-36 scores did not change significantly after low-vision services. The VF-14 mean score improved from 35.8 to 41.2 (P < .001). Four NEI-VFQ subscale scores improved significantly (P < .001): general vision, near activities, distance activities, and peripheral vision. CONCLUSIONS: The SF-36, VF-14, and NEI-VFQ demonstrate that low-vision clinic patients perceive marked impairment of functional status and quality of life. Low-vision services are associated with high patient satisfaction. Vision-targeted questionnaires are more sensitive than general health-related quality of life questionnaires to changes in functional status and quality of life after low-vision services, and they may help elucidate the outcomes of low-vision services.

Effectiveness of monitored anesthesia care in cataract surgery.

OBJECTIVE: To determine the need for monitored anesthesia care in cataract surgery by evaluating the incidence of intervention by anesthesia personnel and by looking for associated risk factors. DESIGN: Nonrandomized, prospective case series with analysis of consecutive cataract surgery cases. PARTICIPANTS: A total of 1006 consecutive cataract surgery patients at an ambulatory surgery center over a 6-month period. METHODS: Routine cataract surgery was performed with the patient under local anesthesia. A detailed questionnaire was completed by the anesthesia personnel at the conclusion of each phase (before, during, and after) of cataract surgery. MAIN OUTCOME MEASURES: Age, medical history, and preoperative electrocardiogram (EKG) were analyzed as predictors for intervention by anesthesia personnel. The nature of the patient's problem and the type of intervention by anesthesia personnel were recorded. RESULTS: In 1006 consecutive cataract surgery cases, intervention by anesthesia personnel was required in 376 (37.4%) cases. No preoperative identifying characteristics were found to be reliable predictors of the need for intervention. There were no statistically significant differences in preoperative EKG and some medical conditions such as heart disease, diabetes, and thyroid disease between patients who received intervention and those who did not. Certain subgroups of patients did show a statistically significantly greater incidence of intervention, including systemic hypertensives (41.4%) versus nonhypertensives (34.5%) (P = 0.030), patients with pulmonary disease (49.3%) versus no pulmonary disease (36.5%) (P = 0.043), patients with renal disease (68.8%) versus no renal disease (36.9%) (P = 0.019), and patients with cancer (61.9%) versus no cancer (36.3%) (P = 0.001). Intervention was also required in 61.1 % of patients younger than 60 years of age compared to 36.5% of those patients 60 years of age and older (P = 0.005). CONCLUSIONS: Because intervention is required in more than one third of cataract surgery cases and the authors cannot reliably predict those patients at risk, monitored anesthesia care seems justified in cataract surgery with the patient under local anesthesia.

Suprachoroidal hemorrhage during pars plana vitrectomy. Risk factors and outcomes.

OBJECTIVE: Suprachoroidal hemorrhage (SCH) is an uncommon but serious complication of pars plana vitrectomy (PPV) that can be associated with a guarded visual prognosis. The purpose of this study is to document the risk factors and outcomes of this complication. DESIGN: Case-control study of consecutive cases of intraoperative SCH occurring during PPV (n = 36) and controls of PPV uncomplicated by SCH (n = 116). MAIN OUTCOME MEASURES: Baseline systemic and ocular characteristics, intraoperative findings, surgical procedures, and final anatomic and visual outcomes were measured. RESULTS: Significant risk factors for the development of SCH during PPV included high myopia (22% of cases vs. 5% of controls), history of retinal detachment (RD) surgery (61% vs. 22%), rhegmatogenous RD (97% vs. 60%), use of cryotherapy (75% vs. 33%), scleral buckling at the time of PPV (50% vs. 19%), external drainage of the subretinal fluid (22% vs. 2%), and intraoperative systemic hypertension. In the 34 SCH cases with 3 months' or more follow-up, the final visual acuity was 20/200 or greater in 11 (32%), count fingers in 5 (15%), hand movement in 7 (21%), light perception in 7 (21%), and no light perception in 4 (12%). In the 106 controls with 3 months' or more follow-up, the final visual acuity was 20/200 or greater in 79 (75%), count fingers in 20 (19%), hand movement in 5 (5%), light perception in 1 (1%), and no light perception in 1 (1%). In the eyes with SCH, 17 (50%) had persistent RD, 10 (33%) had secondary glaucoma develop, and 8 (24%) became hypotonic. The visual and anatomic outcomes of the SCH cases were significantly worse than those in the control group (P < 0.001). The visual outcome was more favorable if the SCH did not extend into the posterior pole (P = 0.002). Attempted intraoperative drainage of SCH was not associated with a better outcome. CONCLUSION: Risk factors for the development of intraoperative SCH during PPV are high myopia, previous RD surgery, rhegmatogenous RD, cryotherapy, scleral buckling, external drainage of subretinal fluid, and intraoperative systemic hypertension. Anatomic and visual outcomes are significantly worsened after this complication.

Visual acuity outcomes of patients 50 years of age and older with high myopia and untreated choroidal neovascularization.

OBJECTIVE: To evaluate visual outcomes of untreated submacular choroidal neovascularization (CNV) in patients 50 years of age and older with high myopia. DESIGN: Retrospective observational case series. PARTICIPANTS: Twenty-two eyes in 22 patients were studied. All were 50 years of age and older with myopia of 6.0 diopters (D) or greater or an axial length of 25.5 mm or greater. Patients had untreated CNV documented by clinical examination and fluorescein angiography at two medical centers between 1986 and 1997. INTERVENTION: Demographic and clinical data were abstracted from patients' medical records. MAIN OUTCOME MEASURE: Visual acuity at 1 year after CNV diagnosis. RESULTS: The study included 22 eyes of 22 patients (mean age, 63.1 years; mean refraction, -11.0 D). Baseline visual acuity (VA) in the study eye was 20/40 or greater in 2 (9%) patients, 20/50 to 20/150 in 9 (41%) patients, and 20/200 or less in 11 (50%) patients. Drusen were present in seven (32%) eyes, and lacquer cracks were noted in ten (45%) eyes. Mean refractive error was -7.0 D for patients with drusen and -12.5 D for patients without drusen. Choroidal neovascularization was less than 0.25 disc diameters (DD) in 11 (50%) eyes, 0.25 to 0.5 DD in 5 (23%) eyes, and greater than 0.5 DD in 6 (27%) eyes. Visual acuity in the study eye 1 year after CNV diagnosis was 20/40 or greater in 3 (14%) patients, 20/50 to 20/150 in 3 (14%) patients, and 20/200 or less in 16 (73%) eyes. The presence of drusen was significantly associated with older age and a lower degree of myopia but was not associated with size of the CNV or visual acuity outcome. CONCLUSION: When compared to patients younger than 50 years of age with high myopia and CNV reported in previous publications, the patients in the current series generally have poorer visual outcomes.

Effects of methylprednisolone and cyclosporine A on fungal growth in vitro.

PURPOSE: The management of corneal transplants after mycotic keratitis often poses a therapeutic dilemma. Clinicians are hesitant to use topical steroids because of their potential enhancement of fungal growth. This study seeks to evaluate the in vitro effects of methylprednisolone and cyclosporine A on the growth of various molds that often are responsible for keratomycoses. METHODS: Fusarium oxysporum, Fusarium solani, and Aspergillus fumigatus were grown in the presence of varying concentrations of methylprednisolone, cyclosporine A, and vehicle controls. Fungal growth was evaluated in a masked fashion based on the number of colonies and their morphologies. RESULTS: All tested concentrations of cyclosporine A (1%, 2%, 4%) had a statistically significant suppressive effect on the growth of F. oxysporum (p<0.001) and F. solani (p<0.001) compared with methylprednisolone and vehicle control solutions. A dose-dependent decrease in the number of colonies grown also was noted for F. oxysporum (p<0.001) and F. solani (p<0.001). In the case of A. fumigatus, cyclosporine A significantly decreased the colony size (p<0.015) in a dose-dependent fashion. CONCLUSIONS: Cyclosporine A appears to have an inhibitory effect on fungal growth in vitro. Cyclosporine A may be an important alternative to topical steroids for management of corneal transplants after mycotic keratitis.

Minor physical anomalies, dermatoglyphic asymmetries, and cortisol levels in adolescents with schizotypal personality disorder.

OBJECTIVE: A relationship between schizotypal personality disorder and schizophrenia has been documented in behavioral genetic studies, and there are similarities in the cognitive deficits and brain abnormalities associated with these disorders. Adolescents with schizotypal personality disorder are of particular interest because the postpubertal period is a critical one for the development of a DSM axis I disorder. It is likely that some schizotypal adolescents will remain stable over time, some will improve, and a subgroup will develop schizophrenia. This study tested the hypotheses that, like schizophrenic patients, schizotypal adolescents manifest an elevated rate of minor physical and dermatoglyphic anomalies, both of which suggest prenatal neurodevelopmental abnormalities. Cortisol release is also of interest because of evidence that the hypothalamic-pituitary-adrenal axis may influence the behavioral expression of vulnerability to schizophrenia. METHOD: Minor physical anomalies, dermatoglyphic asymmetries, and salivary cortisol levels were measured in three groups of adolescents: 20 with schizotypal personality disorder, 20 with other personality disorders, and 26 with no disorder. Assessments began at noon, and four saliva samples were obtained at hourly intervals. RESULTS: The schizotypal personality disorder group showed more minor physical anomalies and dermatoglyphic asymmetries than the normal comparison group and higher cortisol levels than both of the other groups. Group differences in cortisol level were most pronounced at the beginning of the evaluation. Cortisol level and age were positively correlated. CONCLUSIONS: The findings support the assumption that schizotypal personality disorder is associated with perturbations in fetal neurodevelopment and, under some circumstances, a heightened cortisol response.

The therapy of amblyopia: an analysis comparing the results of amblyopia therapy utilizing two pooled data sets.

CONTEXT: We previously presented the results of an original pooled data set of 961 amblyopic patients who underwent patching therapy for amblyopia from 1965 to 1994 (study group 1). Three types of amblyopia were considered: anisometropic, anisometropic-strabismic, and strabismic. Analysis of this group's success was related to the age at which therapy was initiated, the type of amblyopia, and the depth of visual loss before treatment was begun. The purpose of the current study is to test the validity of these findings on a second group of 961 amblyopes employing the data set used by Woodruff and associates in their publications (study group 2). These 2 data sets, after adjustment to conform to the definitions of age, amblyopia, anisometropia, and similar items utilized in common between the 2 study groups, will be compared for the risk factors predictive of successful occlusion therapy. OUTCOME: As in the previous study, the success of occlusion therapy is defined as a visual acuity of 20/40 or better at the end of treatment. RESULTS: Success by the 20/40 criteria was achieved in 73.7% in study group 1 and in 59.9% in study group 2. By category, the rate of success in study group 1 was 77.2% in strabismic amblyopia, 67.2% in anisometropic-strabismic amblyopia, and 66.0% in anisometropic amblyopia. In study group 2, success was 61.2% in strabismic amblyopia, 51.2% in anisometropic-strabismic amblyopia, and 63.0% in anisometropic amblyopia. Study group 1 univariate analysis related success in each group to the age at which therapy was initiated, the type of amblyopia, and the depth of visual loss before treatment in each group. In study group 2, univariate analysis related success of occlusion therapy to age and the depth of visual loss before treatment. Type of amblyopia was not related to outcome success in this group. When the 2 data sets were pooled, the risk factors for success were age and depth of visual loss at onset of treatment. CONCLUSIONS: Factors that appeared closely related to a successful outcome of patching therapy were patient age and depth of visual loss before treatment. These conclusions further support the value of early detection and screening for amblyopia, its prevention, where possible, and its adequate and vigorous treatment when it is detected and diagnosed.

Outcomes of primary trabeculectomy with the use of adjunctive mitomycin.

OBJECTIVE: To investigate the efficacy and safety of adjunctive mitomycin when used during a primary trabeculectomy within a series of 89 consecutive patients at 1 and 2 years postoperatively. DESIGN: A cohort study of all patients who underwent primary trabeculectomy, performed by one of us (P.F.P.), between April 1, 1991, and December 31, 1994. Patients received topical mitomycin in conjunction with a corneal safety valve incision. A trabeculectomy was considered "successful" if it resulted in an intraocular pressure (IOP) of 21 mm Hg or lower and a 30% or greater reduction in the IOP at and after 1 year of follow-up, with or without medications and without a reoperation for an elevated IOP. Survival analysis was used to calculate success rates. RESULTS: The 1- and 2-year success rates were 85.4% and 77.9%, respectively. The mean IOP was reduced from 26.3 to 11.3 mm Hg at 1 year (n=68) and to 11.9 mm Hg at 2 years (n=56), with 60 (88.2%) of 68 patients off medication at 1 year and 47 (83.9%) of 56 patients off medication at 2 years. Trabeculectomy success rates were significantly lower in black compared with nonblack patients (76.2% vs 87.5% at 1 year, P=.03). Trabeculectomy failure occurred throughout the follow-up period. Endophthalmitis occurred in 2 (2.2%) of the patients, and hypotonia requiring revision occurred in 4 (4.5%) of the patients. CONCLUSIONS: Primary trabeculectomy with the use of intraoperative mitomycin lowered the IOP by 30% or more in 78% (at 2 years) to 86% (at 1 year) of the cases and is associated with a marked reduction in the percentage of patients who require glaucoma medication. Success rates must be evaluated in light of such risks as endophthalmitis and hypotony.

Nosocomial acute-onset postoperative endophthalmitis survey. A 10-year review of incidence and outcomes.

OBJECTIVE: The purpose of the study was to evaluate the incidence of acute-onset (within 6 weeks after surgery) postoperative endophthalmitis and to assess the visual acuity outcomes after treatment over a 10-year period at one institution. PATIENTS AND METHODS: This retrospective study reviews all surgical cases performed between January 1, 1984 and December 30, 1994 at the Anne Bates Leach Eye Hospital, Bascom Palmer Eye Institute, University of Miami Medical Center, for the occurrence of nosocomial acute-onset postoperative endophthalmitis. RESULTS: The overall 10-year incidence of acute-onset postoperative endophthalmitis after intraocular surgery was 0.093% (54/58, 123). The incidences of culture-proven acute-onset postoperative endophthalmitis by surgical category were as follows: cataract surgery with or without intraocular lens (IOL) (0.082%, 34/41, 654), pars plana vitrectomy (PPV) (0.046%, 3/6557), penetrating keratoplasty (0.178%, 5/2805), secondary IOL placement (0.366%, 5/1367), glaucoma surgeries (0.124%, 4/3233), combined trabeculectomy and cataract surgery (0.114%, 2/1743), and combined penetrating keratoplasty and cataract surgery (0.194%, 1/515). The median visual acuity after endophthalmitis treatment was 20/200. The median visual acuities after endophthalmitis treatment by procedure were as follows: cataract surgery with or without IOL (20/133), PPV (no light perception), penetrating keratoplasty (2/200), secondary IOL implantation (20/40), glaucoma surgery (20/80), and combined trabeculectomy and cataract surgery with or without IOL (20/150). CONCLUSIONS: The overall incidence of endophthalmitis after intraocular surgery was 0.093%. The incidence of endophthalmitis was higher after secondary IOL implantation than after cataract extraction (P = 0.008, Fisher's exact test). After treatment, the visual acuity outcomes were worse in the patients who developed endophthalmitis after PPV than after cataract extraction, glaucoma procedures, or secondary IOL implantation (P < 0.05, analysis of variance, Duncan's multiple range test). Acuity outcomes after treatment of endophthalmitis were better among the patients with secondary IOL implantation than after penetrating keratoplasty or PPV (P < 0.05, analysis of variance, Duncan's multiple range test). The results of this 10-year review from a large teaching center may serve as a source of comparison for other centers and future studies.

The therapy of amblyopia: an analysis of the results of amblyopia therapy utilizing the pooled data of published studies.

CONTEXT: Although the treatment of amblyopia with occlusion has changed little over the past 3 centuries, there is little agreement about which regimes are most effective and for what reasons. OBJECTIVE: To determine the outcome of occlusion therapy in patients with anisometropic, strabismic, and strabismic-anisometropic amblyopia employing the raw data from 961 patients reported in 23 studies published between 1965 and 1994. DESIGN: Analysis of the published literature on amblyopia therapy results during the above interval, utilizing primary data obtained from the authors of these articles or tables published in the articles detailing individual patient outcomes. PARTICIPANTS: 961 amblyopic patients, participants in 23 studies, undergoing patching therapy for amblyopia from 1965 to 1994 with anisometropia, strabismus, or anisometropia-strabismus. MAIN OUTCOMES: In the pooled data set, success of occlusion therapy was defined as visual acuity of 20/40 at the end of treatment. RESULTS: Success by the 20/40 criteria was achieved in 512 of 689 (74.3%) patients. By category, 312 of 402 (77.6%) were successful in strabismic amblyopia, 44 of 75 (58.7%) in strabismic-anisometropic amblyopia, and 72 of 108 (66.7%) in anisometropic amblyopia. Success was not related to the duration of occlusion therapy, type of occlusion used, accompanying refractive error, patient's sex, or eye. Univariate analyses showed that success was related to the age at which therapy was initiated; the type of amblyopia; the depth of visual loss before treatment for the anisometropic patients and the strabismic patients, but not for the anisometropic-strabismic patients; and the difference in spherical equivalents between eyes, for the anisometropic patients. Logistic/linear regression revealed that 3 were independent predictors of a successful outcome of amblyopia therapy. CONCLUSIONS: Factors that appear most closely related to a successful outcome are age, type of amblyopia, and depth of visual loss before treatment. These may be related to factors, as yet undetermined in the pathogenesis of amblyopia. With present emphasis on the value of screening and prevention and the development of new screening tools, such a look at the results of amblyopia therapy in a large population seems indicated.
