A 69-year-old diabetic male with a prior history of herpes simplex virus (HSV) keratitis presented with reduced vision in his right eye due to diabetic macular edema, which was unresponsive to intravitreal anti-vascular endothelial growth factor injections Fig. 1a. He was on oral Acyclovir prophylaxis. After receiving a dose of intravitreal triamcinolone acetonide, he developed HSV epithelial keratitis Fig. 1b. He was treated with oral Acyclovir 400 mg five times a day, which resulted in the resolution of the ulcer. The macular edema also responded to the intravitreal steroid injection Fig. 1c and d. The recurrence was attributed to local immunosuppression caused by the steroid.1,2Figure 1: (a) Optical coherence tomography suggestive of diabetic macular edema.
