Acute Commotio Retinae Determined by Cross-Sectional Optical Coherence Tomography

PURPOSE: To demonstrate the cross-sectional anatomy in acute commotio retinae. METHODS: A 27-year-old male with unilateral decreased vision after acute blunt ocular trauma, was examined by optical coherence tomography (OCT). RESULTS: Visual acuity was 20/20 OD and 20/50 OS. Fundus examination OS demonstrated a mild edema in the papillomacular and foveal area. OCT confirmed a separation of the neurosensory retina and the retinal pigment epithelium (RPE). The thickness of the retina was normal and the contour of the foveola intact. The uncommon hyperreflective band at the outer retina may present the traumatic disruption of photoreceptors. CONCLUSIONS: In vivo investigations by OCT confirmed previous histological studies, a commotio retinae consists a disruption and fragmentation at the level of the foveal photoreceptor segments and RPE.
