Abstract

We report a case of Descemet's membrane detachment, a rare complication of viscocanalostomy. During the operation, the injection cannula was directed slightly oblique to the Schlemm's canal rather than parallel to it. Localized corneal whitening developed adjacent to the injection site during viscoelastic injection. One week postoperatively, corneal edema decreased and Descemet's membrane detachment was noted. Nine months after surgery, the cornea was clear while the Descemet's membrane detachment remained. And IOP was 19 mmHg without any medications. We think that improper cannula positioning during viscoelastic injection may cause Descemet's membrane detachment, a rare complication of viscocanalostomy.

摘要

我们报告了一例Descemet膜脱离病例，这是小梁切开术的一种罕见并发症。手术过程中，注射套管与施莱姆管呈轻微倾斜而非平行。在粘弹剂注射过程中，注射部位附近出现局限性角膜变白。术后一周，角膜水肿减轻，发现Descemet膜脱离。术后九个月，角膜透明，但Descemet膜脱离依然存在。眼压为19 mmHg，未使用任何药物。我们认为，粘弹剂注射时套管定位不当可能导致Descemet膜脱离，这是小梁切开术的一种罕见并发症。
