ABSTRACT Purpose To systematically review surgical procedure, safety and efficacy of Gonioscopy-Assisted Transluminal Trabeculotomy (GATT). Methods A review of literature was done to analyze all suitable articles from two different databases. Results GATT is effective in reducing intraocular pressure and mean number of medications from baseline. It is associated with minimal complications when compared to ab-externo procedures. It has shorter learning curve and can be performed as primary surgical procedure in moderate-to-severe case of open-angle glaucomas. Conclusion GATT is a minimally invasive surgical procedure for the management of primary and secondary open-angle glaucoma in both adults and children. The advantages of GATT are ab-interno approach, access to open entire natural drainage system, good safety profile and efficacy comparable to trabeculectomy. It can be performed with both illuminated micro-catheter and suture, out of which suture GATT is cost-effective, which is a boon to developing nations.
