Long-Term Use of Topical Carbonic Anhydrase Inhibitor Combined with an Initiation of the Two Different Eyedrops for Persistent Macular Hole Following Vitrectomy Combined with Internal Limiting Membrane Peeling: A Case Report

Abstract

The authors present a long-term course of a woman in her late 50s with persistent full-thickness macular hole (FTMH) after vitrectomy combined with internal limiting membrane peeling subsequently achieved MH closure after receiving topical therapy. Specifically, successful MH closure was observed at eight weeks following an initiation of topical nepafenac, prednisolone acetate, and carbonic anhydrase inhibitor (CAI). Thereafter, the patient was maintained on topical CAI only and achieved 20/32 vision OS with nearly complete restoration of ellipsoidal layers at 18 months postoperative. To conclude, topical therapy may be considered as a non-invasive approach for persistent, cystic, small-apertured MH after vitrectomy procedures. Continuous uses of topical CAI may be of value for sustaining the long-term results.
