Abstract

PURPOSE:

To analyze the incidence of intraocular pressure (IOP) elevation following intravitreal triamcinolone injection.

DESIGN:

Retrospective observational case series.

METHODS:

Charts of patients undergoing intravitreal triamcinolone injection in one clinical practice were reviewed. A pressure elevation was defined as a pressure of 24 mm Hg or higher during follow-up.

RESULTS:

There were 89 patients with a mean age of 76.4 years. The mean baseline IOP was 14.9 mm Hg with a mean change of 8.0 mm Hg. Thirty-six patients (40.4%) experienced a pressure elevation to 24 mm Hg or higher at a mean of 100.6 days (SD = 83.1 day) after treatment. Of nonglaucomatous patients with baseline IOP of 15 mm Hg or above, 60.0% experienced a pressure elevation, compared with only 22.7% of those with baseline pressures below 15 mm Hg (relative risk = 2.1, P < .01). In glaucoma patients, 6 of 12 (50%) experienced a pressure elevation, and this elevation was not correlated with baseline pressure. Thirty-two patients (36.0%) received repeat injections, and there was no difference in the incidence of procedure elevation in patients receiving multiple injections versus those receiving a single injection. Pressure elevation was controlled with topical medications in all patients.

CONCLUSIONS:

IOP elevation after intravitreal triamcinolone injection is common and may take an extended period of time to manifest. The proportion of patients who developed a pressure elevation to at least 24 mm Hg was much higher for those with baseline IOP 15 mm Hg or greater.
