Article
Background: Anterior capsular contraction syndrome (ACCS) describes the progressive fibrotic phimosis of the anterior capsular bag that usually occurs a few months after cataract surgery. YAG laser anterior capsulotomy (YAGAC) is the most common treatment option due to the low-risk profile of this intervention. Purpose: In this series, we evalua...

Article
Choroidal thickness and choroidal vascularity index (CVI) appear to be distorted in eyes with pseudoexfoliation (PEX) syndrome. The accumulation of exfoliation material in the inner wall of choroidal vessels has led to the hypothesis that CVI may be affected both in glaucoma patients and individuals suspected of having glaucoma. The use of the opti...
