Tacrolimus-induced unilateral ischaemic optic neuropathy in a non-transplant patient.

Tacrolimus is commonly used as an immunosuppressant in organ transplantation. Although it is well tolerated, visual loss has been known as a rare but serious complication of this drug. We report a woman developing visual complaints while on tacrolimus therapy for nephrotic syndrome. Omission of the drug led to partial visual field recovery. Visual complications in patients receiving tacrolimus should alert the treating physicians for timely discontinuation of the drug.
