Abstract
Purpose: :
To compare the prevalence of Central Retinal Vein Occlusion (CRVO) in patients with glaucoma associated with XFS (XFSG) versus the prevalence of CRVO in patients with Primary Open–Angle Glaucoma (POAG) in Argentina.
Methods: :
Setting: Two glaucoma referral centers. Study population: 55 consecutive patients with XFSG and 64 patients with POAG, matched for age and sex were prospectively collected. The occurrence of documented CRVO was assessed in both groups. A clinical history was performed and the subjects received a complete ophthalmic examination.
Results: :
CRVO was present in 25.45% of the patients in the XFSG group vs. 10.9% in the POAG group (p<.03). OR to have CRVO for the XFSG group was 2.78 ( 95% confidence interval: 1.05 – 7.30). Logistic regression analysis evaluating the probability of CRVO adjusting by different variables, showed that the OR for the presence of blood hypertension was 2.82 (95% confidence interval: 1.41–1.76), and the OR for the presence of pseudoexfoliation was 3.61 (95% confidence interval: 1.19–10.15).
Conclusions: :
In this glaucoma population CRVO was more frequent in patients with XFSG than in patients with POAG. Both the presence of XFS and blood hypertension may be related to the occurrence of CRVO.
