This 47YO male presented with hand motion vision from a macula-off rhegmatogenous retinal detachment (RRD). The outer retinal folds are dramatically imaged in both the Optos color and green channel images.
Learning Points:
Hydration outer retinal folds are one of the key findings to help differentiate a RRD from exudative and traction retinal detachments.
The cause of these folds remains uncertain but may result from the hydration of glycosaminoglycans in the interphotoreceptor matrix (Dalvin et al, Retinal Cases & Brief Reports 2020;14:355-359).
