Abstract
To determine the changes which occur in the anterior capsule in true exfoliation which is a very rare condition. The anterior capsule from a 93 year-old patient and 6 other patients with age-related cataract during capsulorhexis was examined via transmission electron microscopy (TEM). TEM revealed apoptosis of lens epithelial cells in both two groups. Moreover, we observed lamellar delamination, granular belts in the anterior capsular zone and loss of the subcapsular epithelium cells in the posterior capsular zone, as well as abnormal fibrils located in the central capsular layer only in the sample from the patient with true exfoliation. We suggest that loss of lens epithelial cells and appearance of abnormal fibrils is important in disease developing, and our study supported age-related degeneration is one of causative factors in true exfoliation.
