PURPOSE
To image trabeculectomy blebs before and after laser suture lysis (LSL) using anterior segment optical coherence tomography (AS-OCT).
DESIGN
Prospective observational study.
METHODS
Blebs were imaged with a prototype of the AS-OCT (Carl Zeiss Meditec, Inc, Dublin, California, USA) before and after LSL. Blebs were assessed for bleb height, bleb wall thickness, apposition of the scleral flap to sclera, and patency of the internal ostium.
RESULTS
Seven blebs in eyes of seven patients were imaged. Pre-LSL, five blebs were low and two were of moderate height. After LSL, six of seven eyes (85.7%) showed an increase in total bleb height, with increased bleb wall thickness and separation of the scleral flap from sclera. In one eye, there was no discernible change in bleb height, cavity height, or wall thickness.
CONCLUSIONS
AS-OCT was able to demonstrate features of bleb morphology that changed after LSL.
目的
使用眼前节光学相干断层扫描（AS-OCT）对激光缝线松解术（LSL）前后的小梁切除术滤过泡进行成像。
设计
前瞻性观察性研究。
方法
在LSL前后，使用AS-OCT原型（美国加利福尼亚州都柏林的卡尔·蔡司医疗技术公司）对滤过泡进行成像。评估滤过泡的高度、滤过泡壁厚度、巩膜瓣与巩膜的贴合情况以及内口通畅情况。
结果
对7例患者眼中的7个滤过泡进行了成像。LSL前，5个滤过泡较低，2个为中等高度。LSL后，7只眼中的6只（85.7%）显示滤过泡总高度增加，滤过泡壁厚度增加，巩膜瓣与巩膜分离。1只眼中，滤过泡高度、腔隙高度或壁厚度无明显变化。
结论
AS-OCT能够显示LSL后滤过泡形态的变化特征。
