Purpose:
To report pseudohypopyon after intravitreal triamcinolone acetonide injection for cystoid macular edema.
Design:
Retrospective, noncomparative, consecutive case series.
Methods:
Records were reviewed of all patients who developed pseudohypopyon after intravitreal triamcinolone acetonide injection at Bascom Palmer Eye Institute between January 1, 2002 and February 1, 2004.
Results:
A total of 828 intravitreal triamcinolone acetonide injections were administered to 686 patients during the study period. A pseudohypopyon (fine white crystalline opacities in the inferior anterior chamber angle) and suspended white crystalline opacities in the aqueous humor developed after 7 of the 828 injections (0.8%); all pseudohypopyons occurred within 3 days of injection and resolved completely within 2 weeks. None of the 686 patients developed clinically suspected infectious endophthalmitis.
Conclusions:
A transient pseudohypopyon may occur in the early postinjection period after intravitreal triamcinolone acetonide injection. Unless progressive intraocular inflammation occurs, close observational management is indicated.
