Intraocular Pressure Elevations with Loteprednol Etabonate: A Retrospective Chart Review

Abstract

Abstract

Purpose:

Ocular corticosteroids can cause elevations in intraocular pressure (IOP). The purpose of this study was to characterize the timing and severity of IOP elevations in patients receiving loteprednol etabonate 0.5% or loteprednol etabonate 0.5%/tobramycin 0.3%.

Methods:

A retrospective chart review was conducted at 5 academic and private practices. Any patient who experienced an elevation in IOP ≥5 mm Hg while using loteprednol etabonate or loteprednol etabonate/tobramycin was eligible for inclusion in the study. Data collected included patient demographics, medical and ophthalmic history, concomitant medications, reason for treatment, IOP, and medical and surgical interventions.

Results:

Fifty patients experienced IOP elevations after use of topical loteprednol etabonate and were included in the study. The mean (standard deviation [SD]) patient age was 58.8 (20.3) years and 66% were women. The most common reasons for prescribing loteprednol etabonate were dry eye (30%), postoperative therapy (22%), and allergic conjunctivitis (16%). Before treatment, 28% of patients had a history of open-angle glaucoma or ocular hypertension. Mean (SD) IOP before treatment was 15.5 (3.2) mm Hg and increased to a mean (SD) of 24.7 (6.5) mm Hg, a statistically significant increase of 9.2 (SD: 5.8; range: 5–29) mm Hg (P<0.0001). The median duration of treatment with loteprednol etabonate at the time of observed IOP elevation was 55 days (range: 3 days to 3 years). Twenty-four percent of patients required IOP-lowering medications and 8% required surgery to control the elevated IOP.

Conclusions:

Alternatives to corticosteroids should be considered when long-term treatment is required for an ocular surface condition.
