After three months, the animals were sacrificed and enucleated. Evaluation of PCO included posterior view, migration of anterior capsular epithelial cells to the posterior capsule following epithelial-mesenchymal transition were assessed by staining the histological sections of posterior capsule by hematoxylin-eosin(HE) and Periodic acid- Schiff (PAS). The IOLs were extracted and stained with HE to evaluate the presence of adherent cells on the lens surface. · RESULTS: PCO was highest with round edged rigid lens. There was no significant difference in the PCO between the square edged PMMA and square edged foldable lens.· CONCLUSION: It is the design of the IOL not the material that offers protection on PCO formation.展开更多

Test with fluorescein dye was negative. The dense corneal opacity (macula) was identified as involving the posterior corneal layer. The further ophthalmic examination was done and hypermature phacolytic cataract was diagnosed. No other abnormality was detected. Medical management with topical nepafenac prednisolone and triple antibiotic was instituted. The corneal lesion subsided completely within one week followed by spontaneous resorption of the cataract. The treatment protocol was successfully eliminated the discomfort and intraocular lesions in the senile parrot.展开更多
