Vitreous hemorrhage and retinal vein rupture.

PURPOSE/METHODS: We examined a 23-year-old woman who had a sudden onset of floaters after self-induced emesis. RESULTS/CONCLUSIONS: Examination showed a dense vitreous hemorrhage originating from a rupture site in the wall of the superotemporal branch vein. We postulate a preexisting weakness in the retinal vein wall as a predisposing factor to rupture. This mechanism may explain some cases of vitreous hemorrhage associated with a Valsalva maneuver.

Echography and histological studies in various eye conditions.

A correlation between A-scan echograms recorded clinically in vivo and histological studies of corresponding sections has been made in 42 eyes with intraocular pathological conditions. This study yielded both new and little known acoustic differential criteria for the diagnosis of retinoschisis, funnel-shaped vitreous detachments, serous as well as hemorrhagic retinal and choroidal detachments, intravitreal hemorrhages, and intraocular tumors.

Findings in older children with abusive head injury: does shaken-child syndrome exist?

Shaken-baby syndrome (SBS) has been hypothesized to occur after shaking by an adult during the first 2 years of life. We wondered whether it is possible to achieve rotational forces sufficient to cause SBS-like injuries in children >2 years of age. The present study describes cases of child abuse in older children who presented with the classic ophthalmologic and intracranial findings of SBS. In this case series, 4 cases of older children (2.5-7 years old; 11.8-22 kg) who died from abusive head injuries and who had diffuse retinal hemorrhages identified antemortem were selected for review. The cases were abstracted from hospital charts, records from autopsies, coroners' and district attorneys' offices, and court transcripts. In all 4 cases the history provided by the primary caregiver did not match the severity of the injuries. Three case subjects presented with patterned bruises. Multilayered retinal hemorrhages and acute subdural hematoma were observed in all 4 cases. At autopsy, diffuse axonal injury was evident in 3 of the 4 cases; all 4 cases had optic nerve sheath hemorrhages. None of the victims had skeletal fractures on radiologic examination or at autopsy. This case series demonstrates that it is possible to observe SBS-like retinal and central nervous system findings in the older and heavier child. Our findings underscore the need for providers to consider intentional shaking as a mechanism of injury in the evaluation of abusive head injury in older children.

Ocular tissue involvement in HIV infection: immunological and pathological aspects.

The CNS afflictions in AIDS are myriad and suggest a tropism of HIV to neural tissue. Ocular involvement is a frequent manifestation of the HIV infection, resulting in a high incidence of blindness within this patient population. Ocular lesions include cotton wool spots, presumably from HIV-induced microvasculopathy, retinal hemorrhage in cytomegalovirus retinitis and conjunctival Kaposi's sarcoma. These manifestations have been noted in up to 71% of AIDS patients. In fact, ocular disease is often the presenting symptom in an HIV-infected individual. Despite the high incidence of ocular involvement in AIDS patients, the etiology and pathogenesis of these manifestations are not well understood. The immunosuppressive action of HIV is the most likely primary cause for the development of ocular complications in AIDS. Here we review some of the important immunological and pathological features of AIDS affliction in the eye.

Ocular manifestations and prognosis of secondary glaucoma in patients with carotid-cavernous fistula.

PURPOSE: To study the frequency of ocular manifestations and the prognosis of secondary glaucoma in cases of carotid-cavernous fistula (CCF). METHODS: A retrospective multicenter study was conducted to investigate causes, types, ocular symptoms, complications, treatment, and prognosis in subjects with CCF. RESULTS: Among the 43 patients diagnosed with CCF between 1984 and 2000, a total of 13 patients (14 eyes) showed ocular manifestations. CCF was idiopathic in 13 eyes of 12 subjects and resulted from head trauma in 1 eye of 1 subject. Among the ocular symptoms and complications, conjunctival hyperemia was most common, occurring at a rate of 92.9% of the eyes, followed by exophthalmos at 50%, retinal hemorrhaging at 50%, retinal venous dilation at 42.9%, vascular bruits at 28.6%, injection of Schlemm's canal at 21.4%, and external ophthalmoplegia at 21.4%. Elevated intraocular pressure (IOP) occurred at a rate of 64.3%, with maximum IOP ranging from 22-55 mm Hg. At the time of the final observation, IOP control was favorable in 6 of the 9 eyes showing elevated IOP; 5 of these 9 eyes showed a closed CCF, but none required antiglaucoma treatment, with the exception of 1 eye for which trabeculectomy was performed. IOP control was unfavorable in the remaining 3 eyes, and in 1 of these eyes CCF was not closed. CONCLUSIONS: Secondary glaucoma is a frequently observed ocular manifestation of CCF, and closure of the fistula is the primary condition required for favorable IOP control.

Radiation retinopathy after fractionated stereotactic radiotherapy for optic nerve sheath meningioma.

PURPOSE: To report a patient with radiation retinopathy after fractionated stereotactic radiotherapy for treatment of optic nerve sheath meningioma (ONSM). DESIGN: Interventional case report. METHODS: The clinical presentation, radiation treatment, and subsequent visual complications of a patient with ONSM are described. MAIN OUTCOME MEASURES: Development of radiation retinopathy and Snellen visual acuity. RESULTS: A 36-year-old man presented with a left optic neuropathy. Magnetic resonance imaging studies showed abnormalities consistent with ONSM. Because of progressive vision loss, the patient underwent fractionated stereotactic radiotherapy for the lesion. Vision initially improved after treatment, but 22 months later, retinal abnormalities consistent with radiation retinopathy were noted in the left eye. Visual acuity worsened over the next 24 months in association with the development of retinal hemorrhages, lipid, and retinal edema predominantly within the nasal portion of the posterior pole. Fluorescein angiography showed edema associated with microaneurysms, retinal telangiectasia, and capillary nonperfusion. Laser photocoagulation was performed on several occasions in areas of microaneurysms and retinal telangiectasia; however, the retinal edema and lipid remained, associated with persistent decreased vision. CONCLUSIONS: Radiation retinopathy and vision loss may occur after fractionated stereotactic radiotherapy for ONSM and should be discussed as a potential complication.

Risk factors for the incidence of Advanced Age-Related Macular Degeneration in the Age-Related Eye Disease Study (AREDS) AREDS report no. 19.

PURPOSE: To describe the association of demographic, behavioral, medical, and nonretinal ocular factors with the incidence of neovascular age-related macular degeneration (AMD) and central geographic atrophy (CGA) in the Age-Related Eye Disease Study (AREDS), a randomized trial of antioxidants and zinc supplementation prophylaxis for development of advanced AMD. DESIGN: Clinic-based prospective cohort study. PARTICIPANTS: Of individuals with early or intermediate AMD at baseline with a median follow-up of 6.3 years, 788 were at risk of developing advanced AMD in one eye (the fellow eye had advanced AMD), and 2506 were at risk in both eyes. METHODS: The incidence of neovascular AMD and CGA was assessed from stereoscopic color fundus photographs taken at baseline and at annual visits beginning at year 2. MAIN OUTCOME MEASURES: Neovascular AMD was defined as photocoagulation for choroidal neovascularization, or photographic documentation at the reading center of any of the following: nondrusenoid retinal pigment epithelial detachment, serous or hemorrhagic retinal detachment, hemorrhage under the retina or the retinal pigment epithelium, and subretinal fibrosis. Central geographic atrophy was defined as geographic atrophy involving the center of the macula. RESULTS: In multivariable models, in persons at risk of advanced AMD in both eyes, while controlling for age, gender, and AREDS treatment group, the following variables were statistically significantly associated with the incidence of neovascular AMD: race (odds ratio [OR], white vs. black, 6.77; 95% confidence interval [CI], 1.24-36.9) and larger amount smoked (OR, >10 vs. < or =10 pack-years [a pack-year is an average of 1 pack of cigarette smoked per day for a year], 1.55; 95% CI, 1.15-2.09). The following were statistically significantly associated with the incidence of CGA: less education (OR, high school graduate or less vs. college graduate, 1.75; 95% CI, 1.10-2.78), greater body mass index (BMI) (OR, obese vs. nonobese, 1.93; 95% CI, 1.25-2.65), larger amount smoked (OR, >10 pack-years vs. < or =10 pack-years, 1.82; 95% CI, 1.25-2.65), and antacid use (OR, 0.29; 95% CI, 0.09-0.91). In persons at risk of developing advanced AMD in one eye, the incidence of neovascular AMD was associated with diabetes (OR, 1.88; 95% CI, 1.07-3.31), and the incidence of CGA was associated with use of antiinflammatory medications (OR, 0.22; 95% CI, 0.08-0.59). CONCLUSIONS: Results suggest that, among persons with early or intermediate AMD, smoking and BMI are modifiable factors associated with progression to advanced AMD, and suggest other associations (e.g., use of antacids and antiinflammatory medications) that warrant further study.

Two cases of frosted branch angiitis with central retinal vein occlusion.

BACKGROUND: Frosted branch angiitis usually occurs in children, and has a good prognosis. We report two cases of unilateral frosted branch angiitis in adults. Both had poor visual outcomes because of associated central retinal vein occlusion and neovascular glaucoma. CASES: Case 1 was a 36-year-old woman. Almost all retinal veins and some retinal arteries showed vasculitis in her right eye, and veins were slightly dilated and sheathed. Case 2 was a 23-year-old woman. Angle hypopyon was observed in her left eye. Retinal veins were dilated, meandering, and sheathed. Retinal hemorrhages were also observed. In both cases, after systemic steroid therapy the retinal vasculitis gradually decreased, but central retinal vein occlusions gradually developed. Despite systemic administration of urokinase and panretinal photocoagulation, neovascular glaucoma developed, and visual acuity diminished in both cases. CONCLUSIONS: Two cases of frosted branch angiitis complicated by retinal vein occlusion are reported. Careful observation of retinal blood flow is necessary in frosted branch angiitis in adults.

Unusual immunogammopathy maculopathy.

PURPOSE: To describe an unusual maculopathy in patients with serum immunogammopathies. DESIGN: Retrospective observational small case series. PARTICIPANTS: Three patients derived from the clinical retina practices of the authors were noted to have unusual maculopathy. METHODS: Each patient underwent fluorescein angiography and serum laboratory evaluation. MAIN OUTCOME MEASURE: Findings on fluorescein angiography. RESULTS: An unusual and atypical macular detachment with or without subretinal precipitates or fundus signs of serum hyperviscosity, such as retinal hemorrhages and dilated retinal veins, may be observed in patients with immunogammopathies such as multiple myeloma, Waldenström's macroglobulinemia, and benign polyclonal gammopathy. Fluorescein angiography shows macular hypofluorescence with no evidence of retinal vascular or retinal pigment epithelial leakage within the macular elevation. CONCLUSIONS: Patients with atypical unilateral or bilateral macular detachment may be afflicted with a serum immunogammopathy such as multiple myeloma or Waldenström's macroglobulinemia. Diagnostic serum protein electrophoresis and hematology consultation should be considered.

Retinal angiomatous proliferation: clinical characteristics and treatment options.

BACKGROUND: A new form of exudative age-related macular degeneration (ARMD), retinal angiomatous proliferation (RAP), has been described in which neovascularization begins in the deep retina, extends through the subretinal space, and eventually communicates with choroidal neovascularization. METHODS: Case series. RESULTS: Common clinical features of RAP include small multiple intra-retinal hemorrhages, intra-retinal edema, vascularized pigment epithelial detachments (PEDs), and retinal choroidal anastomosis (RCA). Fluorescein angiography (FA) reveals ill-defined, occult choroidal neovascularization. Indocyanine green (ICG) angiography is useful in early stages because 'hot spots' can be detected before clinical or FA characteristics are present. Optical coherence tomography (OCT) is useful in illustrating some of the clinical and FA characteristics. The use of photodynamic therapy (POT), combined with intravitreal triamcinolone injection, was successful in stabilizing the RAP lesion in one case discussed in this report. CONCLUSIONS: Retinal angiomatous proliferation is a newly recognized entity of exudative age-related macular degeneration with its own set of clinical, FA, ICG angiography, and OCT features. Experimental treatments such as the use of PDT combined with intravitreal triamcinolone injection demonstrate potential success with this entity. The biggest hope appears to be anti-angiogenic factors currently in clinical trials for the treatment of exudative ARMD.

Ocular findings in neonates after extracorporeal membrane oxygenation.

Extracorporeal membrane oxygenation (ECMO) is a modified, prolonged cardiopulmonary bypass procedure used to treat newborns who have reversible cardiac or respiratory failure. The venoarterial bypass technique requires cannulation of both the right carotid artery and the internal jugular vein, and after decannulation these vessels are permanently ligated. Left-sided retinal vascular changes after ECMO have been reported, and were attributed to ligation of these vessels. A retrospective review of the results of ocular examinations of 86 infants who had undergone ECMO therapy at Childrens Hospital in Los Angeles between March, 1987 and May, 1991 was conducted. Normal findings were noted in 73 infants. One infant had bilateral retinal vascular tortuosity, and 12 infants had incidental ocular findings, but there was no evidence of left-sided retinal hemorrhage, venous congestion, or tortuosity. Our results suggest that left-sided retinal vascular changes after ECMO do not occur, occur only rarely, or clear rapidly and result in no permanent retinal damage. To unequivocally rule out the possibility that ECMO can cause transitory retinal vascular changes, we recommend further prospective studies, with ocular examinations performed before, during, and after ECMO.

[Macular diseases--application of automated static perimetry and optical coherence tomography].

The usefulness of automated static perimetry and optical coherence tomography in the management of macular diseases has been described. Scotomata in eyes with central serous chorioretinopathy could be evaluated with central 10-degree automated static perimetry. The degree of visual field defects in eyes with the disease varied greatly with mean deviation of -10 dB or less in as many as 10% of the subjects. Although retinitis pigmentosa is a diffuse retinal dystrophy, eyes with a moderately advanced stage of retinitis pigmentosa should be managed as a macular disease, because the functioning retina is confined within the vascular arcade. The progressive nature in this stage of the disease could be demonstrated with a central 10-degree automated static perimetry measured once or twice a year and the use of univariate linear regression of mean deviation, in half of the patients with a mean follow-up period of 5 years. Functional recovery in eyes with exudative age-related macular degeneration after laser surgery or submacular surgery could be evaluated with central 10-degree automated static perimetry. Eyes with increased mean deviation in spite of reduced visual acuity after therapeutic intervention should also be evaluated. Macular function could also be evaluated using a color test. A newly developed color saturation discrimination test was applied to patients with age-related macular degeneration, retinitis pigmentosa, and cone dystrophy. The degree of dyschromatopsia was less in eyes with age-related macular degeneration than in those with retinitis pigmentosa or cone dystrophy with the same level of acuity loss. The highly protrusive nature of the orange-red nodule in eyes with idiopathic polypoidal choroidal vasculopathy was demonstrated with dimensional measurement with OCT. The degree of protrusion was greater than in eyes with serous pigment epithelial detachment, which suggests that the polypoidal lesion is covered with rigid tissues including Bruch's membrane. Parafoveal retinal sensitivity obtained with automated static perimetry was studied in correlation with retinal thickness measured using OCT in eyes with branch retinal vein occlusion showing macular edema without macular non-perfusion or massive retinal hemorrhages. The increased retinal thickness due to macular edema is closely correlated with retinal sensitivity both at the fovea and in the parafoveal area. Eighty-nine phakic eyes of 46 patients with retinitis pigmentosa patients were studied to detect cystoid macular edema using OCT. Cystoid lesions were observed in the macula in 12 eyes in 6 (13%) of 46 patients. Some eyes with OCT-proven cystoid macular edema did not show dye pooling in the fluorescein angiogram. The width of the total area of cystoid lesions was positively correlated with best-corrected visual acuity but the thickness of the neurosensory retina at the center of the fovea was not. OCT findings of successfully repaired macular holes were categorized into 3 groups. Eyes with U-type showed a normal foveal contour and a dark layer corresponding to the outer segment of photoreceptors. Eyes with V-type showed a notch in the surface of repaired neurosensory retina without a dark layer on the retinal pigment epithelium. Those with W-type showed a defect of the neurosensory retina, where the retinal pigment epithelium was exposed. The visual results were excellent in eyes with U-type, but poor in those with W-type.
