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.
