Optical coherence tomography findings in niacin maculopathy.
METHODS
We present the case of 54-year-old male who developed bilateral cystoid macular thickening while taking 3 g of niacin per day, and we describe the optical coherence tomography (OCT) features of niacin (nicotinic acid) maculopathy.


CONCLUSIONS
Cystoid spaces were seen in both the outer plexiform and inner nuclear layers of both eyes. The cystoid spaces were largest and central in the outer plexiform layer, whereas a broader distribution of smaller cysts was seen in the inner nuclear layer. With cessation of niacin, his vision improved and the OCT features normalized.
