目的：探讨前节OCT(AS-OCT)在内眼术后角膜后弹力层脱离诊治中的临床应用价值。

方法：回顾性分析2016-06/2019-04我院眼科行内眼术后发生角膜水肿的患者21例23眼，均采用AS-OCT检查观察角膜水肿程度及角膜后弹力层脱离情况。对于轻度及以上角膜后弹力层脱离者应用前房注气法复位，余角膜水肿者予以药物保守治疗，随访观察角膜水肿及后弹力层贴附情况。

结果：本研究纳入患者21例23眼内眼术后均有不同程度角膜水肿，14眼角膜后弹力层脱离，其中11眼轻度及以上角膜后弹力层脱离予以前房注气后1d复查AS-OCT，10眼后弹力层贴附良好，1眼贴附欠佳，再次注气后贴附良好。随诊1mo，所有患者角膜均恢复透明，视力恢复良好。

结论：AS-OCT能够及时、准确诊断和评估角膜后弹力层脱离及其治疗效果。

METHODS: Totally 23 eyes of 21 patients with corneal edema after intraocular surgery in our hospital from June 2016 to April 2019 were analyzed retrospectively. The degree of corneal edema and the descemet's membrane detachment(DMD)were observed by AS-OCT. The patients with mild or above descemet's membrane detachment were treated with anterior chamber gas tamponade, the patients with other corneal edema were treated with drug conservative treatment, and the corneal edema and adhesion of descemet's membrane were observed.

RESULTS: In this study, 21 patients(23 eyes)had corneal edema of different degrees, 14 eyes with descemet's membrane detachment,11 eyes with mild or above descemet's membrane detachment were re-examined by AS-OCT one day after anterior chamber gas tamponade. 10 eyes had good adhesion, 1 eye had poor adhesion, and the adhesion was good after anterior chamber gas tamponade again. After 1mo follow-up, the cornea of all the patients recovered to be transparent and their vision recovered well.

CONCLUSION:AS-OCT can timely and accurately diagnose and evaluate descemet's membrane detachment and its therapeutic effect.
