A 27-year-old man presented with decreased visual acuity in his right eye 2 months after an altercation in which he experienced blunt trauma to the affected eye. Visual acuity was counting fingers OD at 2 ft. No pupillary abnormality was detected. An ophthalmoscopic examination revealed a choroidal rupture with an overlying epiretinal membrane (Figure).
Choroidal rupture typically results from trauma and may lead to subsequent formation of epiretinal or subretinal neovascular membranes. Traumatic epiretinal membranes may develop from retinal glial cells that extend onto the retinal surface through breaks in the internal limiting membrane that are formed at the time of the trauma.1
