PURPOSE
To report the use of slit-lamp-adapted optical coherence tomography (SL-OCT) in imaging 2 patients with Descemet membrane detachment following anterior chamber reformation after trabeculectomy.
METHODS
Two patients, with leaking and overfiltering blebs, respectively, developed Descemet detachments after reformation of flat anterior chambers with viscoelastics. Slit-lamp biomicroscopy and SL-OCT were used to diagnose and monitor posttreatment outcome.
RESULTS
Biomicroscopic evaluation and SL-OCT imaging of the cornea revealed a Descemet detachment in both cases. One patient underwent intracameral air injection. Follow-up SL-OCT imaging revealed reattachment of Descemet membrane and reduced corneal thickness.
CONCLUSIONS
SL-OCT can be used to document and follow postsurgical detachment of Descemet membrane.
目的
报告 2 例小梁切除术后前房重建后发生的角膜后弹力层脱离（Descemet 膜脱离）患者使用裂隙灯适配光学相干断层扫描（SL-OCT）进行成像的情况。
方法
分别有 2 例患者在前房成形术中使用粘弹剂后发生渗漏和滤过过强，导致扁平前房再形成，之后发生了 Descemet 脱离。使用裂隙灯生物显微镜和 SL-OCT 对患者进行诊断并监测治疗结果。
结果
在这两种情况下，通过角膜生物显微镜检查和 SL-OCT 成像评估均发现有 Descemet 脱离。其中 1 例患者接受了眼内注气治疗。SL-OCT 随访成像显示，Descemet 膜重新附着，角膜厚度减少。
结论
SL-OCT 可用于记录和随访术后发生的 Descemet 膜脱离。
