Traumatic retinal pigment epithelial edema.

A 17-year-old girl was struct in the right eye by a mortarboard tossed into the air during high school graduation exercises. She suffered commotio retinae with damage to the retinal pigment epithelium and macular hole formation. Fluorescein angiography in the acute stages revealed diffuse staining at the level of the pigment epithelium. Five months later, the areas of abnormal staining had undergone depigmentation and dye no longer accumulated in the pigment epithelial layer. The fluorescein findings in traumatic retinal pigment epithelial edema are unusual.
