Progressive hemifacial atrophy (Parry-Romberg syndrome): report of two cases.

We describe 2 cases of progressive hemifacial atrophy (Parry-Romberg syndrome) with typical facial and ocular involvement. Ocular manifestations in these 2 cases include enophthalmos, due to fat atrophy, decreased corneal sensitivity, episcleritis, and band keratopathy. The slowly progressive changes were documented in one case over a 40 year period. Both cases were unilateral with limitation of the lesions at the midline.
