对先天性青光眼患者施行房角镜辅助的经腔小梁切开术(GATT)等手术，由于难于观察到房角结构，可能会多次出现困难。角度标志识别不准确可能导致各种不经意的手术并发症。因此，在这些手术过程中，需要技术来改善外科标志物的可视化。在这项研究中，在外科医生进行GATT之前，使用0.2%吲哚青绿(ICG)对TM进行染色。通过赋予明亮的绿色色调，它产生了良好的小梁网状结构的分化。5/5例成功确定了切开部位，随后360°置管术。ICG辅助SC识别有助于儿童先天性青光眼的房角手术，特别是对结构分化差的眼。
Performing procedures like gonioscopic assisted transluminal trabeculotomy (GATT) in eyes with congenital glaucoma may be difficult many a times due to difficult visualisation of angle structures. Inaccurate identification of angle landmark may lead to various inadvertent surgical complications. Hence, there is a need for techniques to improve visualisation of surgical landmarks during these procedures. In this study, 0.2% indocyanine green (ICG) was used to stain the TM before the surgeon proceeded with GATT. It yielded excellent differentiation of the trabecular meshwork by imparting a bright green hue. This led to successful identification of the site of incision and subsequent 360° cannulation of Schlemm’s canal (SC) in 5/5 cases. ICG aided SC identification is helpful in children with congenital glaucoma undergoing angle surgeries, especially in eyes with poor structure differentiation.
