Peripapillary Subretinal Space of the Blunt Traumatic Optic Neuropathy: RPE/Bruch’s Membrane Complex Micro-Rips - The Novel SD-OCT Findings

Abstract

Aim: To report the unusual SD-OCT findings in peripapillary subretinal space of the blunt traumatic optic neuropathy (TON). Methods: All patients underwent a comprehensive eye examination included color fundus photography, ultrasonography, fundus fluorescein angiography, visual field, PVEP if patient’s vision was allowed to examine. An orbital CT scan was performed for all of patients and no orbital fracture was found. However, we did not assess them here and assessed the results of SD-OCT examination only. Results: Peripapillary subretinal spaces of four contused eyes were abnormal that showed a flat, localized hyperreflection due to hemorrhages. It was adjacent to optic disc. The intensities of reflection could be nonuniform due to the blood concentration or contained serous liquid. It could be observed that RPE/Bruch’s membrane complex micro-rips, but ELM were normal that were not involved in the peripapillary subretinal space. Choroid rupture of macula was observed at times. Conclusion: For TON patients, to examine the peripapillary subretinal space by SD-OCT at first time might have valuable for diagnosis. The results suggested that the hemorrhages of peripapillary subretinal space might come from the peripapillary choriocapillaris.
