A 56-year-old man presented with anterior chamber inflammation, increased intraocular pressure, peripheral retinal infiltration, and generalized retinal arterial obstruction suggesting acute retinal necrosis five months after intravitreal triamcinolone acetonide injection (IVTA). He was treated with intravenous antiviral agents and aspirin. Shortly after treatment, retinal infiltrations were resolved, and partial recanalization of the obstructed vessel was observed. Viral retinitis may occur as an opportunistic infection following IVTA due to the local immune modulatory effect of the steroid; hence, close observation following IVTA is necessary.
