Abstract

Background: To present the iridectomy combined with posterior approach anterior chamber gas injection technique for the treatment of extensive Descemet's membrane detachment (DMD), which is a novel surgical approach for the management of DMD after phacoemulsification.

Case presentation: The surgical technique was performed on a 68-year-old female with a history of cataract phacoemulsification surgery and two times of anterior chamber gas injection to treat DMD. After creating a scleral tunnel at 4 o'clock of the limbus, the iris root in that direction was cut off. This was confirmed via an iris root incision indicating that the syringe needle entered the posterior chamber through the scleral tunnel. The anterior chamber was filled about 3/4 with 16% C3F8. After surgery, patients were required to maintain a supine position without pillows. One month post-surgery, the cornea was transparent, DMD had fully recovered, and the best corrected visual acuity improved to 20/20.

Conclusions: The iridectomy combined with a posterior approach anterior chamber gas injection technique can be used as an alternative surgical option for the management of extensive DMD in patients who have undergone several ineffective anterior chamber gas injection surgeries.

虹膜切除术联合后入路前房气体注射技术：一种治疗大面积Descemet膜脱离的新技术。

背景：介绍虹膜切除联合后路前房气体注射技术治疗广泛性Descemet膜脱离（DMD），这是一种治疗超声乳化术后DMD的新手术入路。病例介绍：该手术技术应用于一位68岁女性，有白内障超声乳化手术史，两次前房气体注射治疗DMD。在角膜缘的4点钟位置形成巩膜隧道后，这个方向的虹膜根被切断。这是通过虹膜根部切口证实的，表明注射器针头通过巩膜隧道进入后房。前房约3/4填充了16%的C3F8。术后患者需保持仰卧位，不带枕头。术后1个月，角膜透明，DMD完全恢复，最佳矫正视力提高至20/20。结论：虹膜切除术联合后路前房注气技术可作为治疗多次前房注气手术无效的广泛性DMD患者的替代手术选择。
