Imaging hydration folds following retinal detachment repair.

A 53-year-old male underwent retinal detachment (RD) repair surgery in left eye. Postoperatively, fundus showed hydration folds [Fig. 1a], which were hypoautofluorescent on blue autofluorescence [Fig. 1b]. Spectral domain optical coherence tomography (SD-OCT) demonstrated outer retinal folds as hyperreflective lesions in outer retina [Fig. 1c].

Color fundus photograph (a) of left eye showed hydration folds (blue arrows) and silicon oil reflex (black arrow). Blue autofluorescence (b) showed hypoautofluorescence (arrows) in the corresponding areas of hydration folds. Spectral domain optical coherence tomography (c) demonstrated outer retinal folds as focal hyperreflective lesions in outer retina (arrow). External limiting membrane and ellipsoid zone appear to be involved in the folds extending into outer nuclear layer

Partial-thickness folds of inner and outer retina or full-thickness folds may occur after RD repair surgery.[12] SD-OCT can be used to differentiate between them.[3] Partial-thickness folds can improve spontaneously with time and have good visual outcome.[4] However, full-thickness folds involving fovea need to be treated surgically.[5]
