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.
