title: Restored photoreceptor outer segment in commotio retinae.
abstract: The authors report the retinal findings of the healing phase in commotio retinae. Retinal images were obtained using spectral-domain optical coherence tomography (SD-OCT) on 3 eyes from 3 patients with commotio retinae after blunt ocular trauma. The best-corrected visual acuity (BCVA) and fundus appearance from the medical records were retrospectively studied. All cases had commotio retinae in the posterior pole. OCT showed increased reflectivity of the line at the junction between the photoreceptor inner and outer segments (IS/OS) in the area of the opacified retina in all cases. The initial BCVA in cases 1, 2, and 3 was 1.5, 1.2, and 0.7, respectively. In all eyes, the neurosensory retinal edema had resolved and the IS/OS line returned to normal architecture. The final BCVA in cases 1, 2, and 3 was 2.0, 1.5, and 1.5, respectively. The authors found restored photoreceptor outer segment in commotio retinae by SD-OCT and improvement of BCVA.
