Fig. 3From: Macular edema after rhegmatogenous retinal detachment repair: risk factors, OCT analysis, and treatment responsesSpectral-domain optical coherence tomography (OCT) images of chronic cystoid macular edema (CME) post-rhegmatogenous retinal detachment (RRD) repair of the left eye, with dates and visual acuities (VA). Panel A: OCT prior to dexamethasone implant (DEX) injection. Panel B: OCT 1 month after DEX injection, showing resolution of CME but retinal layer atrophy. Modest VA improvement was noted. Panel C: OCT four months after injection, showing recurrence of CME in a similar distribution and slight decrease in VABack to article page
