A rare case of subclinical scotoma: When the infrared read it better

Abstract

Commotio retinae (CR) are a disorder of the outer retina, typically following a blunt trauma to the eye. CR leads to visual disturbances mainly in the form of a scotoma. CR clinically presents as a transient gray-white discoloration of the retina and is diagnosed with ease. There are reports of CR presenting without any retinal discoloration but confirmed on optical coherence tomography, or infrared retinal reflectance termed subclinical scotoma. We present one such rare case of subclinical CR without clinical findings, which was diagnosed on infrared reflectance overlay showing a characteristic distinct hyporeflectance pattern.
