In 26 patients (11 women and 15 men) with acute retinal vascular occlusion, the courses of spontaneous and collagen-induced thrombocyte aggregation were investigated 1 to 14 days (mean 6.8 +/- 4.8 days) after the onset of the symptoms and before the start of treatment, by means of the platelet aggregation test (PAT III) described by Breddin et al. (1975a). The results were compared with those of a control group consisting of 37 age-matched glaucoma and cataract patients (20 women and 17 men) with no vascular occlusions. Thrombocyte aggregation was high in 59.5% of the patients in the control group and 100% of the patients with retinal vascular occlusion. This would appear to show that pathological elevation of thrombocyte aggregation has considerable pathogenetic significance as an inducing factor of retinal vascular occlusion in the presence of concomitant arterial sclerosis and that treatment with inhibitors of thrombocyte aggregation would be appropriate.

The relationship between oral contraceptive (OC) use and eye disease was investigated through abstraction of salient data from the two large British cohort studies of the effects of OCs: the Royal College of General Practitioners' (RCGP) OC Study and the Oxford-Family Planning Association (FPA) Contraception Study. Together, these studies have accumulated over 850,000 person-years of observation since 1968 involving 63,000 women. The conditions considered in the analysis were conjunctivitis, keratitis, iritis, lacrimal disease, strabismus, cataract, glaucoma, retinal detachment, and retinal vascular lesions. The only eye disease for which there was consistent evidence of a notable increase in risk in OC users was retinal vascular lesions. The relative risk of retinal vascular lesions in OC users compared to never users was 2.0 (95% confidence interval (CI), 1.0-3.8) in the RCGP data set and 2.4 (95% CI, 0.4-9.2) in the Oxford-FPA Study. This increased risk was not concentrated in any one diagnostic category (e.g., retinal vascular occlusion, retinal vein thrombosis, retinal hemorrhage).

Familial exudative vitreoretinopathy (FEVR) is a rare inherited disorder of retinal angiogenesis. A 49-year-old male patient was referred to our clinic for retinal vascular occlusion. His history, clinical findings, and fundus fluorescein angiography findings were evaluated. Family members were called and eye examinations were performed. Our patient was not born preterm and he reported decreased visual acuity after a traffic accident during childhood. He had laser treatment when he was 12 years old and again 1 month before our examination. He also had laser-assisted in situ keratomileusis surgery for both eyes in 2002. On examination, his visual acuity was 0.4 in the right eye and 0.3 in the left eye. He had cortical cataract in both eyes. Macula OCT revealed macular contour irregularity due to epiretinal membrane in his right eye and minimal perifoveal thinning in his left eye. On fundus photography, straightening of the retinal vessels, macular dragging, retinal folds on temporal retina, preretinal fibrosis, and laser spots were seen. FFA revealed avascular retinal areas with incomplete laser spots in the temporal, inferior, and superior parts of retina. He also had neovascularization with leakage in the temporal retina of his right eye. The patient's brother, who was also born at full term, also had excessive branching of the vascular structures in the temporal peripheral retina, non-perfused cord vessels and avascular areas. In light of all these findings, we diagnosed our patient with Stage 2A FEVR and his brother with Stage 1 FEVR. In summary, FEVR is a clinically diagnosed disease. Because FEVR is inherited and potentially sight-threatening, family examination is helpful and important so that affected family members can be diagnosed and followed up.
