Andrés Suárez-Campo, María López-Valladares Abstract ID: WGCSUB-1775 Surgical management of hemorrhagic Descemet’s membrane detachment after deep sclerectomy Andrés Suárez-Campo, María López-Valladares Glaucoma Unit.

Spain PURPOSE: To describe a case of hemorrhagic Descemet's membrane detachment following deep sclerectomy and to discuss its surgical management. METHODS: Interventional case report. CASE REPORT: A 74-year-old woman suffering with chronic open-angle glaucoma, dry eye syndrome and intolerance to glaucoma medications underwent an uncomplicated deep sclerectomy combined with phacoemulsification and intraocular lens implantation. One week after the surgery, the patient presented with a hemorrhagic Descemet's membrane detachment (DMD) in the upper quadrants (IOP 14 mmHg) (Fig. 1A). Two weeks after the surgery, the hemorrhagic detachment did not show any change (Fig.1B). The anterior segment OCT (Zeiss Cirrus HD-OCT 4000) showed a Descemet’s detachment with a hyperreflective homogeneus content (Fig.2). Since the hemorrhage showed limited improvement after 4 weeks (Fig. 1C), we decided to perform a surgical evacuation. Under topical anesthesia and after air injection into the anterior chamber, we performed a 2 mm partial corneal thickness incision near the limbus, in the Descemet’s membrane detachment area. After partial draining of the hemorrhage through this incision, 15% sulphur hexafluoride (SF6) was injected in the anterior chamber. 24-hours after the surgical drainage, we observed a residual DMD in the upper nasal quadrants (Fig. 2A). During the following weeks, slowly reabsorption of the blood was noticed with progressive increase of hemosiderin deposition at the lower area, and complete resolution of the DMD (Fig. 2B and 2C). The bleb was not functionally impaired during the postoperative period, and intraocular pressure remained under 13 mmHg without medication. 15 months after surgical drainage, the Descemet's membrane remained completely reattached, and a small area of corneal blood staining persisted in the pre-Descemet space (Fig. 2D), outside the visual axis, and the visual acuity without correction was 20/30.

CONCLUSIONS: Hemorrhagic Descemet's membrane detachment is a rare complication after deep sclerectomy. Surgical evacuation through a partial corneal incision prevents further complications, as corneal scarring and vision loss. REFERENCES: 1. Kozobolis VP, Christodoulakis EV, Siganos CS, Pallidaris IG.
