On optical coherence tomography (OCT) of the macula, a patient with central serous chorioretinopathy (CSCR) shows which characteristic finding in the outer retinal layers?

• A Hyperreflective dots in the inner nuclear layer
• B Sub-retinal fluid with intact ellipsoid zone (EZ) and RPE undulation/detachment ✓
• C Disruption of the EZ with intra-retinal fluid
• D Hyper-reflective epiretinal membrane with tractional retinal detachment

Explanation

CSCR classically demonstrates sub-retinal fluid (SRF) on OCT with an intact photoreceptor ellipsoid zone and a focal or broad RPE detachment (pigment epithelial detachment) underlying the SRF. The EZ is initially preserved, distinguishing it from wet AMD where the EZ is disrupted. Intra-retinal fluid and ERM are features of other macular conditions.
