Prevalence and Associations of Retinal Vein Occlusion in Australia
TLDR
This study emphasizes RVO as an important cause of unilateral visual loss in an older population of permanent residents from an area west of Sydney, Australia and suggests a likely selection bias in previous clinic studies.Abstract:
\m=ge\49 years), representing 88% of the permanent residents from an area west of Sydney, Australia, underwent a detailed eye examination, including stereophotography (Zeiss). The diagnosis of RVO was made clinically and from photographic grading. Results: Signs of RVO were found in 59 participants (1.6%; 95% confidence interval, 1.3-1.9). The prevalence for each age-specific participant was as follows: 0.7%, younger than 60 years; 1.2%, 60 to 69 years; 2.1%, 70 to 79 years; and 4.6%, 80 years or older. There was no significant sex difference in prevalence. Branch RVO was observed in 41 subjects (69.5%); of this number, 10 subjects had branch RVO outside the vascular arcade or in the nasal fundus and 3 subjects developed new vessels. Hemispheric RVO was found in 3 subjects (5.1%), and central RVO was observed in 15 (25%); RVO was bilateral in 3 subjects (5.1%). Visual acuity was affected most in the people with central RVO, with a visual acuity of 20/200 or less in 60% compared with 14% among the people with branch RVO. Retinal vein occlusion was the fifth most frequent cause of unilateral blindness in this population. Significant associations with RVO were found with glaucoma, hypertension, stroke, and angina. Conclusions: This study emphasizes RVO as an important cause of unilateral visual loss in an older population. The proportion of the 3 vein occlusion sites shows some differences from those of clinic-based reports and suggests a likely selection bias in previous clinic studies.read more

TL;DR: In this paper, the authors conducted a case-control study of risk factors for retinal vein occlusions using 87 patients with vein occlation, chosen randomly from photographic files from their institution between 1985 and 1990, and a control group of 85 subjects 38 years of age or older, who were randomly selected from the records of two general ophthalmologists in the department.
