Ocular manifestations and treatment of hemifacial atrophy.

Enophthalmos, flattening of the maxilla that may progress to inferior orbital rim and floor defects, eyelid atrophy, and slight relative hypotony occurred in patients with hemifacial atrophy. Less common manifestations included pupillary and iris abnormalities, vertical muscle imbalances, and retinal changes. The prognosis for vision was good. Fluid silicone injection was the major modality in treatment and the results were generally excellent.
