Signs. Retinal thickening is best detected by slit-lamp biomicroscopy with a contact lens, though high-resolution non-contact lenses are also effective.

FA shows diffuse late hyperfluorescence due to retinal capillary leakage, and may have a flower-petal pattern if CMO is present

OCT shows retinal thickening and, if present, cystoid spaces . OCT is also useful in assessing response to treatment.
