Closure of Macular Holes With Topical Therapy

Purpose: To report the results of a nonsurgical approach to repair macular holes (MHs). Methods: A retrospective chart review of consecutive patients with MHs from 2018 to 2021 was performed. Topical therapy consisted of a steroidal agent, a nonsteroidal agent, and a carbonic anhydrase inhibitor. Data collected included the size, stage, and duration of the MH; topical agents used and the duration; lens status; and complications. Macular edema was graded on a scale ranging from 0 (no edema) to 4 (large amount of edema) and recorded. Before and after MH closure, the best-corrected visual acuity (BCVA) was measured and converted to logMAR notation. Spectral-domain optical coherence tomography was performed. Results: Seven (54%) of the 13 eyes initially treated topically experienced successful MH closure. Small holes (<230 µm) with a better initial BCVA (0.474 logMAR vs 0.796 logMAR) were more likely to respond favorably to topical therapy (mean 121 µm vs 499 µm). In addition, holes with less surrounding edema responded better. All holes not responding to topical therapy were subsequently closed with pars plana vitrectomy, membrane peeling, and fluid-gas exchange. Conclusions: Topical therapy is a reasonable first-line treatment for MHs, with a better than 50% success rate. This is especially true for small early-onset holes with minimal or no edema. Surgery still had a high success rate after a 1- to 3-month delay while the MH was treated with eyedrops.
