To study the efficacy of air descemetopexy in the management of various types of descemet membrane detachment based on anterior segment – optical coherence tomography & to know the role of other gases Perfluoropropane (14% C3F8) and sulphur hexafluoride (20% SF6) in failed cases of air descemetopexy

Abstract

Purpose: To study the efficacy of air descemetopexy in the management of various types of descemet membrane detachment (DMD). Materials and Methods: After ethical committee approval, clinical data of 40 patients during the period of December 2017 to December 2018, who developed DMD after cataract surgery were analysed. Results: Majority of patients (n= 32, 80%) had severe generalized corneal edema, n = 4 had moderated corneal edema & n = 4 had localized mild corneal edema. Only air was sufficient to reattach DMD in majority of the patients (n=36, 90% cases), only 4 patients who had very large dmd failed to attach by air. In these patients repeat descemetopexy by 14% C3F8 gas was done which lead to attachment of descemet membrane with improvement of visual acuity in 3 cases. Complications due to increase intraocular pressure were noted with these gases. Conclusion:Air descemetopexy is a safe & efficacious option for DMD repair in most of the cases and it is associated with less postop complications.

Management of Descemet’s Membrane Detachment after Cataract Surgery—A Case Series

“…Since then, both air and SF 6 have been used widely but no strong evidence supports what is the more appropriated gas to deal with DMD. Chaurasia et al and Singh et al have suggested air descemetopexy as a safe treatment option for DMD in most patients [11,12]; however, some researchers prefer the long-lasting effect of SF 6 descemetopexy [1,13]. Air resolution occurs within 3-4 days and might not be long enough for reattachment of the DM.…”
