Abstract

Purpose: We present a case of traumatic commotio retinae (CR), in which blood flow was evaluated using optical coherence tomography angiography (OCTA).

Observations: An 18-year-old Japanese man presented with traumatic retinal detachment and CR in his left eye, which had been hit by a handball. Fundus examination revealed peripheral retinal tear extending from the 1 to 3 o'clock position with retinal detachment, and CR near the area of tear. Fluorescein angiography (FA) confirmed an ischemic area near the retinal tear area at the CR. The patient underwent successful scleral buckling and cryopexy. Sequential OCTA imaging was performed and we were able to determine perfusion in the CR area, with maintained blood flow.

Conclusions and importance: In blunt eye trauma, peripheral commotio retinae can be assessed non-invasively over time using OCTA. OCTA is a useful method for evaluating peripheral retinal whitened areas.
