[Retinal detachment with retinal tears--clinical characteristics and surgical results].

The authors evaluate a group of 53 eyes of 52 patients operated on account of retinal detachment with an oral dialysis. The mean follow-up period was 35 months. There were 37 (70%) traumatic dialyses. They were in the temporal lower quadrant in 58%, in the nasal upper quadrant in 16%, temporal upper quadrant in 13% and in the nasal lower quadrant in 13%. There were 16 (30%) idiopathic dialyses, all with one exception in the temporal upper quadrant, they were in the lower temporal quadrant. 52 eyes were operated primarily cryosurgically, one eye by pars plana vitrectomy. After primary surgery the retina adhered completely in 94% eyes. On account of relapses of detachment 9.4% eyes were reoperated. At the end of the follow up the retina adhered completely in 94% eyes. Functional improvement or stabilization of vision was achieved in 78% eyes with traumatic tears and in 87% eyes with idiopathic tears. The authors confirmed the existence of two different clinical entities--traumatic and idiopathic oral dialysis which differ as to site and to a certain extent also the prognosis of the disease.

The influence of subconjunctival depot corticosteroid on choroidal detachment following retinal detachment surgery.

This study indicates that primary retinal detachment surgery on patients aged 55 or over is complicated by uveitis and choroidal detachment at approximate rates of 24% and 44%, respectively. These complications did not influence the anatomic cure rate or recovery of visual acuity. Although only 89 patients were recruited, the technique of random selection equally distributed the parameters studied and provided results of high reliability. The internal controls of the protocol prevented the examiners from being aware of whether the drug or placebo had been administered. We were concerned that the corticosteroid injection might have been producing the apparent increase in infection rate of 7.7% and the study was temporarily discontinued. Because statistical analysis showed there was no significant difference in infection rate between the treatment and control groups, the project could have been continued again.

Persistent foveal retinal detachment after successful rhegmatogenous retinal detachment surgery.

PURPOSE: To describe the tomographic features of the neurosensory retina after successful rhegmatogenous retinal detachment surgery. DESIGN: Cohort study. METHODS: We prospectively examined cross-sectional retinal images using optical coherence tomography (OCT) in 15 eyes of 15 consecutive patients (mean age, 46 years) who underwent scleral buckling surgery for treatment of rhegmatogenous retinal detachment. The retinas appeared reattached upon binocular stereoscopic indirect ophthalmoscopy. All eyes were examined at 1, 3, 6, and 12 months postoperatively. The time from onset of subjective symptoms of retinal detachment to retinal surgery ranged from 4 to 66 days (mean, 14 days). The postoperative OCT findings and best-corrected visual acuity were statistically analyzed using the Mann-Whitney U test. RESULTS: The detached retinas appeared attached on ophthalmoscopy in all eyes 1 month postoperatively. OCT showed residual retinal detachment in four eyes (27%) at the fovea and in three eyes (20%) at the fovea and adjacent area. The remaining eight retinas (53%) were attached when examined tomographically. In six of the seven eyes with residual foveal detachment by OCT, the retinas reattached spontaneously up to 12 months postoperatively. The postoperative best-corrected visual acuity improved gradually during 12 postoperative months in all 15 eyes. A substantial increase in visual acuity occurred when the fovea reattached in the six eyes with residual detachment. CONCLUSIONS: Foveal retinal detachment may persist after successful retinal detachment surgery in eyes in which the fovea appeared to be attached on ophthalmoscopy. The residual foveal detachment may explain, in part, the delayed visual acuity improvement after successful scleral buckling.

Adult retinopathy of prematurity: outcomes of rhegmatogenous retinal detachments and retinal tears.

PURPOSE: To describe the results of retinal tears and rhegmatogenous retinal detachments (RD) in adults with retinopathy of prematurity (ROP). DESIGN: Noncomparitive interventional case series. METHODS: Retrospective cohort of 216 eyes of 108 patients, 15 years or older, followed for up to 23 years (median, 6.2 years). RESULTS: One eye was initially seen with an RD, and during follow-up 30 eyes had an RD develop. An additional surgical procedure was required in 7 of the 31 eyes (23%) with an RD. Four eyes were initially seen with retinal tears, and during follow-up 19 eyes had a retinal tear develop. Seven of the 23 eyes (30%) with a retinal tear had initial repair fail. Eyes with minimal cicatricial changes from ROP were still at high risk for tears and detachments developing. Eighty percent of eyes with retinal tears and 60% of eyes with an RD that started with vision >20/60 maintained that level of vision at the final examination. CONCLUSION: In patients with a history of premature birth, features of fundus examinations do not correlate with the occurrence of a retinal tear or RD. Repair of a tear or detachment in such a patient is more likely to require multiple procedures but can still be associated with good visual results. Physicians should consider widespread relief of vitreoretinal traction for a tear or detachment in any patient with a history of premature birth.

Posterior vitreous detachment and retinal detachment after cataract surgery.

OBJECTIVE: To evaluate possible changes of vitreous status in emmetropic eyes after uneventful phacoemulsification surgery, and possible related complications such as the onset of retinal detachment (RD). DESIGN: Retrospective case series. PARTICIPANTS: Four hundred fifty-three emmetropic eyes from 453 patients (mean age, 62.03+/-5.57 years) subjected to uneventful phacoemulsification with intraocular lens implantation in the capsular bag were considered in the study. They had a refractive error within +/-0.5 diopters (mean, -0.21+/-0.08). Eyes with peripheral retinal lattice degeneration were included only if asymptomatic and only if the degeneration involved one retinal quadrant. After cataract surgery, the 453 eyes were evaluated preoperatively at days 1, 15, and 30 and months 3, 6, 12, 18, 24, 36, 48, and 60. The whole period of follow-up was 5 years. METHODS: Evaluation of vitreous status by biomicroscopic examination, indirect binocular ophthalmoscopy, and B-scan ultrasonography. MAIN OUTCOME MEASURES: Postoperative onset of posterior vitreous detachment (PVD) and RD. RESULTS: After cataract surgery, a PVD occurred in 107 of 141 (75.88%) eyes without preoperative PVD or lattice degeneration. Posterior vitreous detachment occurred in 41 of 47 eyes (87.23%) with preoperative lattice degeneration and no PVD. Eyes with preoperative lattice degeneration and postoperative PVD showed a higher incidence of RD after cataract surgery (21.27%) than eyes without preoperative PVD or lattice degeneration (0.70%). In all patients with lattice degeneration, RD originated from horseshoe retinal tears on lattice areas located on the superior quadrants. No correlation was observed between the development of RD and age. CONCLUSIONS: Our results suggest that the onset of postoperative PVD should be considered an important risk factor for the development of RD after cataract surgery, particularly in eyes with lattice areas.

Increased nitric oxide (NO) pathway metabolites in the vitreous fluid of patients with rhegmatogenous retinal detachment or diabetic traction retinal detachment.

BACKGROUND: Nitric oxide (NO) plays a significant role in physiological and pathological processes in the retina. In the L-arginine-NO pathway, NO synthase (NOS) converts L-arginine to NO and L-citrulline. Increased NO production, mediated by inducible NOS has been implicated in the pathogenesis of various vitreoretinal diseases. In the present study it is hypothesized that in rhegmatogenous retinal detachment (RRD), the production of NO pathway metabolites might be upregulated. METHODS: Using high-pressure liquid chromatography citrulline, arginine and nitrite were measured in vitreous fluid of 93 eyes with RRD, nine eyes with a traction retinal detachment due to proliferative diabetic retinopathy (PDR), and in 49 control samples of vitreous fluid from eyes without retinal detachment. RESULTS: The mean vitreous concentrations of citrulline and arginine were significantly increased in eyes with RRD (9.6+/-4.3 and 97.3+/-29.2; respectively) or in eyes with a traction retinal detachment (25.8+/-10.3 and 130.7+/-23.7; respectively) as compared to control eyes (7.1+/-3.2 and 75.9+/-18.1; respectively). The mean level of nitrite was also higher in vitreous fluid of patients with RRD (2.24+/-1.4) or patients with a traction retinal detachment (2.21+/-0.72) than in the controls (2.01+/-0.72), although not significantly so. CONCLUSIONS: We found increased levels of NO pathway metabolites in the vitreous fluid of eyes with retinal detachment, which may reflect a possible role of NO in the pathogenesis of this disease.

[Retinal detachment after perforating eye injuries. III. Analysis of retinal detachment after perforating eye injuries and determination of the characteristics of the retinal detachment after perforating eye injuries].

In 1977-1987 the authors operated, using the cryosurgical method post-traumatic retinal detachment in 69 patients. Retinal detachment developed in 37 patients after simple perforation of the eye by a foreign intraocular body. In all patients the perforation penetrated as far as the vitreous space. In patients with retinal detachment the authors investigated the following: the patient's age, refraction, period of retinal detachment, extent of retinal detachment, the state of the macula, the characteristics of the retinal defect (site, size and number), type of retinal detachment and associated adverse factors. In the characteristics of retinal detachment after perforating eye injuries the first place was held by prognostically adverse vitreous traction in 73.9%.

Management of pseudophakic retinal detachment with undetectable retinal breaks.

BACKGROUND AND OBJECTIVE: Difficulties encountered during the repair of pseudophakic retinal detachment are related to difficulties in peripheral retinal visualization and identification of retinal breaks. The implication of nonvisualized breaks in patients with pseudophakic retinal detachment is associated with lower rates of surgical success. This report decribes the results of a prospective trial to evaluate the efficacy of both scleral buckling surgery in the treatment of pseudophakic retinal detachment with undetected retinal breaks and pars plana vitrectomy techniques in the management of the cases that redetected after primary buckling surgery. PATIENTS AND METHODS: This study represents 25 cases of pseudophakic retinal detachment with undiagnosed retinal breaks. In each case, we performed a scleral buckling that extended over the circumference of the retinal detachment. Pars plana vitrectomy with internal subretinal fluid drainage and long-term tamponade were performed on 7 patients with uncomplicated recurrent retinal detachments after primary buckling surgery. The mean duration of follow up was 32 months. RESULTS: There were 25 eyes (24.5%) of pseudophakic retinal detachment with undiagnosed retinal breaks represented in our pseudophakic retinal detachment cases. Anatomic success was achieved after the initial scleral buckling surgery in 18 eyes (72%). The overall success rate was 92%. The visual acuity was 20/40 or better in 8 patients (32%), 20/80 to 20/40 in 6 patients (24%), 5/200 to 20/80 in 7 patients (28%), and light perception to hand movement in 4 patients (16%). Complications included vitreous hemorrhage, macular pucker, cystoid macular edema, and hypotony with proliferative vitreoretinopathy. CONCLUSION: Scleral buckling surgery in conjunction with cryotherapy is effective in the initial treatment of pseudophakic retinal detachment with undetectable retinal breaks. Pars plana vitrectomy with internal fluid-gas exchange and long-term tamponade can be used to treat these patients with recurrent retinal detachment after primary buckling surgery to get a higher overall success rate.

The relationship between refractive errors and retinal detachment--analysis of 1,166 retinal detachment cases.

We compared 1,166 eyes with retinal detachment to 11,671 eyes of patients without retinal detachment in order to clarify the distribution of refraction ranges and the relative frequency in incidence of retinal detachment for each range. In the retinal detachment group, hyperopia was detected in 8.58%, emmetropia in 9.26% and myopia in 82.16%, and the corresponding ratios in the control group were 24.29%, 41.30% and 34.41%, respectively. The retinal detachment group thus exhibited a high frequency of myopia, as has been known. The relative frequency of retinal detachment for each range of refraction was 0.35 for hyperopia, 0.22 for emmetropia and 0.83 for myopia in the range -0.75 to -2.75 D. The relative frequency increased with an increase of severity in myopia up to the range of higher than -15.0 D, where the frequency was 68.6 times higher than for the hyperopic range.

Retinal detachment caused by retinal dialysis.

PURPOSE: To determine the characteristics of patients developing retinal detachment secondary to retinal dialysis in Western Australia and to confirm the clinical impression that these patients had a low rate of proliferative vitreoretinopathy (PVR). METHODS: A retrospective analysis of the records of 1601 consecutive patients with rhegmatogenous retinal detachment identified 71 patients in whom the retinal detachment was caused by a retinal dialysis. RESULTS: The majority of these patients were young adults (mean age of 30 years) and the male to female ratio was 1.3:1. Seventy per cent of patients provided a history of significant trauma to the affected eye. Sporting injuries, assault, and motor vehicle injuries together accounted for 72% of identifiable trauma. Examination revealed a dialysis of the inferotemporal quadrant in 75% of cases and despite obvious signs of chronicity of the associated retinal detachment (such as intraretinal macrocysts and demarcation lines) in approximately one-third of the eyes, only 5.6% developed grade CI PVR either pre- or postoperatively. CONCLUSION: The present study supports the view that it is the low rate of PVR that explains the good prognosis and high surgical success rate for retinal detachments caused by retinal dialysis. It is postulated that a major reason for the low rate of PVR is that the vitreous base attachment to the posterior margin of a retinal dialysis acts as a significant barrier to the migration of potentially proliferative retinal pigment epithelial cells. This may lead to containment of the responsible proliferative cells within the loculated subretinal space.
