Abstract

Purpose: To investigate the structural features of outer retinal atrophy secondary to closed-globe trauma and their correlation with visual prognosis, using spectral domain optical coherence tomography (OCT).

Methods: In this retrospective study, patients with outer retinal atrophy secondary to closed-globe trauma were examined with Topcon 3D OCT-1000. The foveal thickness was measured. The severity of outer retinal atrophy was graded into three levels: disruption of inner/outer segment (IS/OS) layer, reduced thickness of outer nuclear layer (ONL), and disappearance of ONL. Cases with > 180 days of follow-up were included. The correlations between OCT features and best-corrected visual acuity at the last follow-up were analyzed.

Results: Overall, 52 eyes of 52 patients were included, with mean follow-up of 286 ± 200 days. Spectral domain OCT revealed disruption of the inner/outer segment (IS/OS) layer with atrophy of outer nuclear layer and disorganization of inner retina in severe cases. The final best-corrected visual acuity was significantly correlated with foveal thickness (r = - 0.813, p<0.001) and grade of outer retinal atrophy (r = 0.796, p<0.001).

Conclusions: Spectral domain OCT revealed disruption of IS/OS layer and atrophy of outer nuclear layer in cases of commotio retinae. Foveal thickness and grade of outer retinal atrophy were predictors for final visual outcome in these cases.
