Optical coherence tomography (OCT) was done in 20 eyes to detect causes of poor visual outcome, at least three months after successful management of endophthalmitis, which obtained clear media and best corrected visual acuity of < 20/40. Only four (20%) eyes had normal foveal contour on OCT. Eleven (55%) eyes showed treatable lesions, including epiretinal membrane with macular thickening in five (25%), epiretinal membrane without macular thickening in three (15%), cystoid macular edema in two (10%) and subfoveal serous detachment in one (5%) eye. Five eyes (25%) had foveal atrophy. OCT was helpful in segregating treatable conditions like cystoid macular edema from nontreatable causes like neurosensory atrophy in the postendophthalmitis patients.
