Case Diagnosis

The correct diagnosis of cystoid macular edema (CME) was made on the basis of decreased vision, history of cataract extraction, and macular changes seen on funduscopic examination. It was later confirmed with the presence of cystic fluid spaces on optical coherence tomography (OCT).

Diabetic macular edema is unlikely because the patient did not report systemic diabetes. Although the diabetes might have gone undiagnosed, diabetic macular edema is unusual in the absence of diabetic retinopathy in either eye.

Age-related macular degeneration (AMD) may involve macular edema and is often a bilateral yet asymmetric condition. However, no drusen was noted in either eye, which is one of the hallmark signs of AMD.

Retinal vein occlusion was ruled out owing to the absence of hemorrhages in the retina.

Uveitis was not considered because of the lack of anterior chamber reaction and the clear vitreous in both eyes.
