Effects of second and multiple injections of intravitreal Kenalog on visual acuity and intraocular pressure.

Abstract

Abstract: : Purpose: To describe the effect of repeat injection of intravitreal Kenalog (IVK) on visual acuity and intraocular pressure (IOP). Methods: A retrospective chart review was conducted on 17 eyes from 15 patients who underwent repeat injection of IVK. One patient in the series underwent three IVK treatments. Results: The average follow–up was 160 days. The average LogMAR gain after the first IVK was 0.069 (3.5 letters Snellen equivalent). The average LogMAR gain after the second IVK was 0.015 (1 letter). The maximum IOP after the first injection was 32 and after the second was 52. 8 out of 15 patients required glaucoma medicines. One patient required a glaucoma consult for uncontrolled IOP. Conclusions: A second IVK treatment may be associated with modest visual improvement and an increased risk of IOP rise.
