To identify cystoid macular edema (CME) in patients with retinitis pigmentosa (RP) using optical coherence tomography (OCT) and to evaluate response to acetazolamide by serial OCT. ⋯ These results indicate that OCT is a valuable tool in the detection and follow-up of CME in RP patients. Treatment with acetazolamide resulted in marked improvement in OCT-diagnosed CME in RP, but visual improvement was variable.
