Stromal corneal dystrophy (possible Schnyder's dystrophy) with peripheral corneal degeneration - diagnostic and therapeutic challenges.

to highlight the diagnostic and therapeutic challenges in a case with central and peripheral corneal lesions. We present the preoperative investigations: anterior segment optical coherence tomography and ultrasound biomicroscopy; The excised cornea has been examined histopathologically. Preoperative assessment showed that peripheral lesion was not ectatic; Histopathological examination points to a possible corneal degeneration, with posttraumatic or infectious etiology for the peripheral lesion and gives some reasons to sustain the diagnosis of Schnyder's dystrophy for the central lesion. The association of different corneal lesions may need many investigations to establish the diagnosis and choose the most appropriate therapeutic solution.
