The authors present the case of a 73-year-old woman affected by geographic atrophy (GA) in her left eye.

Abstract
The authors present the case of a 73-year-old woman affected by geographic atrophy (GA) in her left eye. During her follow-up, she developed a subretinal hyporeflective space visible on optical coherence tomography (OCT) images. This peculiar OCT sign was recognized to represent a wedge-shaped subretinal hyporeflectivity (WSSH). In contrast to previous reports showing that WSSH develops during the flattening of drusenoid pigment epithelium detachment (PED), the authors found that the WSSH manifestation may be even consecutive to the regression of a large PED and consequent GA appearance. Therefore, the origin of this peculiar OCT finding could be more complex and variegated.
