超声生物显微镜在白内障术后角膜后弹力层脱离诊断中的应用

Diagnose of descemet's membrane detachment by UBM

目的观察超声生物显微镜(UBM)在白内障术后角膜后弹力层脱离的诊断中的应用价值。方法对9例(9眼)出现角膜后弹力层脱离,采取眼科超声生物显微镜检查,明确诊断后,将脱离的角膜后弹力层手术复位。结果复位术后第1d 7例角膜水肿明显减轻,1周后完全恢复透明。2例于复位术后3d角膜仍明显水肿,复查UBM见后弹力层在位,分别于术后12d及15d角膜恢复透明。结论UBM是诊断角膜后弹力层脱离的有效手段,尤其是在角膜水肿时它的应用既避免了误诊又为治疗赢得了时间。

Objective To use UBM diagnose deseemet＇ s membrane detachment and observe its advantage. Methods There are 9 descemet＇s membrane detachment cases were examined by UBM. The range and distance of detachment were checked. The detachmented descemet＇ s membrane were treated based on UBM. Results 7 case＇s （7 eyes） corneal edemas were lightened evidently after surgery and transparent completely. Two case＇ s （2 eyes ） cornea was still edema. The descemet＇ s membrane wasn＇ t detachment by UBM. After 12 days and 15 days,the transparency of cornea resumd. Conclusions UBM can check patients earlier, don＇ t affected by corneal edema. So it can improve this diagnose of deseemet＇ s membrane detachment, make it probably to treate these patients earlier.
