Abstract

PURPOSE:: To evaluate the occurrence, management, and clinical significance of increases in intraocular pressure (IOP) in patients with diabetic macular edema treated with dexamethasone intravitreal implant (DEX implant). METHODS:: Randomized, multicenter, 3-year, Phase III study. Patients (N = 1,048) with diabetic macular edema were randomized to DEX implant 0.7-mg, DEX implant 0.35-mg, or sham procedure with retreatment allowed at ≥6-month intervals (seven injections maximum). RESULTS:: In the DEX implant 0.7-mg, DEX implant 0.35-mg, and sham groups, respectively, ≥10-mmHg IOP increases from baseline occurred in 27.7%, 24.8%, and 3.7% of patients, and their frequency did not increase with repeat injections. IOP-lowering medication was used by 41.5%, 37.6%, and 9.1% of patients. Only one patient (0.3%) in each DEX implant group had filtering surgery to manage a steroid-induced IOP increase. Among DEX implant 0.7-mg–treated patients with and without a ≥10-mmHg IOP increase, 21.9% (21 of 96) and 22.4% (57 of 255), respectively, achieved ≥15-letter best-corrected visual acuity gain at the end of the study, and mean average change in central retinal thickness from baseline was −127 μm and −106 μm, respectively. CONCLUSION:: DEX implant demonstrated clear benefit of treatment despite increases in IOP. Sequential implants had no cumulative effect on IOP.This is an open access article distributed under the terms of the Creative Commons Attribution-NonCommercial-NoDerivatives License 4.0 (CC BY-NC-ND), which permits downloading and sharing the work provided it is properly cited.
