Digital image capture and automated analysis of posterior capsular opacification.
PURPOSE To develop and validate a digital imaging and analysis technique for assessing the extent of posterior capsular opacification after cataract surgery. METHODS Retroillumination images of the posterior capsule were obtained by using a digital camera mounted on a slit lamp. The images were analyzed using an available image analysis software program. The image acquisition and analysis tec...
متن کاملEffect of anterior capsular polishing on the rate of posterior capsule opacification: A retrospective analytical study.
AIM To determine whether anterior capsule polishing during cataract surgery done by phacoemulsification has any effect on the rate of posterior capsule opacification. MATERIALS AND METHODS We conducted a 3 year retrospective analytical study at our hospital. The medical records of patients who underwent cataract extraction by phacoemulsification with foldable square edge hydrophilic PCIOL bet...
متن کاملCurrent improvements in interpretation of posterior capsular opacification images
We present application of curvature-driven min/max flow and anisotropic diffusion in processing posterior capsular (PCO) images. PCO images present the back surface of the lens implanted during cataract surgery and are used to monitor the state of patient vision. Our standard segmentation technique which based on variance based co-occurrence matrices often requires an enhancement of variance im...
متن کاملPrevention of posterior capsular opacification through aldose reductase inhibition.
PURPOSE The purpose of this study was to evaluate the effect of aldose reductase (AR) inhibition on posterior capsular opacification (PCO) with the use of a pig eye capsular bag model. METHODS Pig eye capsular bags were prepared by capsulorhexis and cultured in medium without or with AR inhibitors for 7 days. Immunostaining was performed in paraformaldehyde-fixed capsular bags to determine th...
متن کاملPrevention of posterior capsular opacification through cyclooxygenase-2 inhibition
PURPOSE To determine if cyclooxygenase-2 (COX-2) is upregulated when lens epithelial cells (LEC) in clinical samples of cataracts and posterior capsule opacification (PCO) undergo epithelial-mesenchymal transition (EMT)-like changes. We also wanted to learn if inhibition of the enzymatic activity of COX-2 could prevent PCO formation. METHODS To ensure that EMT-like changes were occurring in L...
