[Surface atypia following recurrent corneal lesions (light and electron microscopy findings)]

A case of recurrent herpetic keratitis was followed by therapy-resistant corneal opacities. Histological sections revealed epithelial ectopias in superficial stromal layers of the cornea; their formal pathogenesis appears to be due to defects in Bowman's membrane. Another patient developed several intraocular complications after a penetrating corneal injury, and each surgical intervention resulted in increasing corneal decompensation. Semithin and ultrathin sections of the explant revealed endothelial metaplasia with fibroblastic activity.
