Abstract

Purpose: To evaluate the safety and efficacy of a dexamethasone sustained-release intraca-nalicular insert (DII) (Dextenza® Ocular Therapeutix, Inc., Bedford, MA) for control of inflammation and pain after pars plana vitrectomy (PPV) compared to standard topical steroid therapy. Methods: Retrospective, case-matched comparison of consecutive patients undergoing PPV. Control patients were matched by diagnosis and procedure performed. The primary outcome was the proportion of patients with complete anterior chamber cell clearance (ACCC) at postoperative day 7. Secondary outcomes included proportion developing intraocular pressure (IOP) >25 mmHg, change in mean optical coherence tomography central foveal thickness (OCT CFT), and proportion developing cystoid macular edema (CME) on qualitative analysis of OCT. Results: The DII group had a statistically significant higher rate of complete ACCC compared to the topical steroid group (65% versus 35%, respectively, with p=0.01). No eyes had IOP >25 mmHg in the DII, compared to 2 eyes in the topical steroid group (not statistically significant). Overall, mean OCT CFT decreased in both groups; one patient had CME in the DII group, as compared to three in the topical steroid group (not statistically significant). Conclusion: The dexamethasone intracanalicular insert provided excellent safety and efficacy in control of postoperative inflammation following PPV in this retrospective case-matched study.
