Trabeculectomy is considered as the gold standard for surgical treatment of glaucoma. The use of conjunctiva to create a filtering bleb limits future surgical options. Gonioscopy-assisted transluminal trabeculotomy (GATT) is an ab interno trabeculotomy technique that has the advantage of reducing the intra-ocular pressure (IOP) in a conjunctiva sparing manner. Ten eyes of eight patients underwent GATT and were followed up for a minimum period of 6 months. Eight eyes were not on any glaucoma medication till the end of their last follow-up, which ranged from 6 months to 1 year. Two eyes were advised to undergo additional glaucoma surgery. All eyes except one retained their visual acuity in the post-operative follow-up period. GATT is a promising technique for the treatment of mild to advanced open-angle glaucoma with an added benefit of sparing the conjunctiva for future interventions.
