OCULAR HYPERTENSION AFTER INTRAVITREAL INJECTION OF 2-MG TRIAMCINOLONE

Purpose: To report the incidence and course of ocular hypertension after intravitreal injection of 2-mg triamcinolone acetonide (IVT). Methods: In a retrospective, consecutive series, all patients receiving 2-mg IVT at a single institution between March 1, 2012, and March 1, 2017, with a minimum of 3-month follow-up were reviewed. Ocular hypertension was defined as an intraocular pressure (IOP) measurement over 24 mmHg at any follow-up visit after IVT. Patients receiving topical, periocular, or intravitreal corticosteroid other than 2-mg IVT were excluded. Results: A total of 106 eyes in 100 patients receiving at least one injection of 2-mg IVT were included. Eyes received an average of 2.9 injections (range 1-17), and average patient follow-up was 15.1 months (range 3.0-52.5 months). A total of 14 eyes (13.2%) in 14 patients developed ocular hypertension after a median of 1.5 injections (range 1-9) with an average peak IOP of 29 mmHg (range 25-38 mmHg). Overall, a total of 11 eyes (10.4%) had an IOP elevation >= 10 mmHg above baseline at any point after first IVT. In all cases of ocular hypertension, IOP was successfully managed with observation or topical IOP-lowering medication alone; no patients required surgical intervention. Conclusion: Ocular hypertension developed in 13.2% of eyes receiving intravitreal injection of 2-mg triamcinolone acetonide. Incidence of ocular hypertension after 2-mg IVT compares favorably with other intravitreally administered corticosteroids.
