In vivo confocal microscopy in recurrent granular dystrophy in corneal graft after penetrating keratoplasty

Abstract

Two case reports of recurrent granular dystrophy in corneal grafts after penetrating keratoplasty are presented. Slit-lamp examination and confocal microscopy (HRT II) were performed in two patients with recurrent granular dystrophy. All confocal microscopic findings of granular dystrophy were evaluated in the graft. Dystrophic lesions of the donor cornea presented the same confocal microscopic aspects in both eyes, and were similar to granular dystrophy lesions. Confocal microscopy is an imaging method that may provide new information on corneal microanatomy in dystrophies. It may be particularly useful in improving the early diagnosis of dystrophic lesions in corneal grafts.
