Abstract
To describe the application of full-thickness compression corneal sutures along with intracameral gas injection in a case of non-resolving long-duration hydrops of pellucid marginal corneal degeneration with a large Descemet membrane (DM) tear. Corneal hydrops is a complication of conditions such as keratoconus (KC), pellucid marginal corneal degeneration (PMCD), and keratoglobus. Intracameral gas injection in the form of sulfur hexafluoride (SF6) or perfluoro propane (C3F8) has been known to shorten the recovery period by tamponading the break. The application of corneal sutures to approximate the widely separated ends of the DM tear may also be performed. All these are management options described for acute hydrops. We report two cases of application of full-thickness compression corneal sutures along with intracameral gas injection in a case of non-resolving long-duration hydrops of more than 2 months duration in PMCD with a large DM tear. Full-thickness corneal compression sutures and intracameral gas injection can restore the imperviousness of posterior stroma after hydrops. This technique is safe and effective for faster resolution of corneal edema post hydrops and early visual rehabilitation.
