To report the incidence and management of Descemet membrane detachment (DMD) after canaloplasty.
Review of all patients who developed DMD after canaloplasty at Tulane Glaucoma Services was performed. Visual acuity, intraocular pressure, and number of glaucoma medications up to 1 year of follow-up were included in the analysis.
The incidence of DMD was 7.4% (12 eyes of 162). Eighty-three percent (10/12) of the DMDs involved the inferior quadrants and measured <3 mm. Intracorneal hemorrhage within DMD occurred in 58% (7/12), whereas 42% (5/12) developed DMD with intracorneal viscoelastic (Healon GV) alone. Two patients had large detachments measuring 5 to 6 mm extending into the visual axis. DMD resolved completely with or without drainage except for 1 patient who developed corneal decompensation, needing penetrating keratoplasty.
DMD with or without intracorneal hemorrhage is not an infrequent complication of canaloplasty and can occasionally lead to corneal decompensation.
报告房水引流物植入术后发生的后弹力层脱离(DMD)的发生率和处理方法。
回顾在杜兰眼科青光眼服务中心行房水引流物植入术后发生 DMD 的所有患者。分析视力、眼压和 1 年随访期间使用的青光眼药物数量。
DMD 的发生率为 7.4%(162 眼中的 12 眼)。83%(10/12)的 DMD 累及下象限,且范围<3mm。58%(7/12)的 DMD 伴有角膜内出血,而 42%(5/12)的 DMD 仅伴有角膜内黏弹剂(Healon GV)。2 例患者的脱离范围较大,达 5-6mm,并延伸至视轴。除 1 例发生角膜失代偿,需要穿透性角膜移植外,DMD 经或不经引流均可完全缓解。
DMD 伴或不伴角膜内出血是房水引流物植入术的一种常见并发症,偶尔会导致角膜失代偿。
