Performing procedures like gonioscopic assisted transluminal trabeculotomy in eyes with congenital glaucoma may be difficult many a times due to difficult visualization of angle structures. Inaccurate identification of the angle landmark may lead to various inadvertent surgical complications. Hence, there is a need for techniques to improve visualization of surgical landmarks during these procedures. In this study, 0.2% indocyanine green was used to stain the trabecular meshwork before the surgeon proceeded with gonioscopic assisted transluminal trabeculotomy. 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 degrees cannulation of Schlemm canal in 5/5 cases. Indocyanine green aided Schlemm canal identification is helpful in children with congenital glaucoma undergoing angle surgeries, especially in eyes with poor structure differentiation.
在患有先天性青光眼的眼睛中进行房角镜辅助经瞳孔小梁切开术等手术有时可能很困难，因为难以观察到房角结构。如果不能准确识别房角标志，可能会导致各种意外的手术并发症。因此，需要有一些技术来改善这些手术过程中手术标志的可视化。在这项研究中，在外科医生进行房角镜辅助经瞳孔小梁切开术之前，使用 0.2%吲哚菁绿对小梁网进行染色。这通过赋予明亮的绿色色调，出色地区分了小梁网。这导致在 5/5 例中成功识别了切口部位，并随后对 Schlemm 管进行了 360 度插管。吲哚菁绿辅助 Schlemm 管识别有助于接受角度手术的先天性青光眼儿童，尤其是在结构分化较差的眼睛中。
