Evaluation of posterior Capsular opacification in Dogs – a review of 12 Cases

Abstract

Posterior capsule opacification (PCO) is the most common long-term postoperative complication following cataract surgery. It causes impaired visual acuity by directly blocking the visual axis. Posterior capsule opacification (PCO) is the most common long-term postoperative complication following cataract surgery, also called as after cataract or secondary cataract. PCO results from the growth and abnormal proliferation of Lens Epithelial Cells (LECs) on the capsule at the time of cataract surgery. These cells migrate to the posterior capsule where they approach the central visual axis and cause visual axis obstruction, resulting in dimness of vision ⁽²⁾. The severity of PCO was greater in canine patients which might be related to the differences in inflammatory and fibrous response. While it was more difficult to quantify, it was likely that PCO represents a significant cause of reduced visual acuity in dogs after cataract surgery ⁽¹⁾ .
