Modern view of using gonioassociated trabeculotomy

Abstract

Purpose. Provide data on the use of gonioscopy-assisted transluminal trabeculotomy (GATT), reflecting its effectiveness and safety when using this technique in various patient models. Material and methods. To perform the review, literature sources which were searched through the PubMed and Scopus databases up to and including 2021, using the keywords “gonioassociated trabeculotomy”, “minimally invasive glaucoma surgery”, “primary open-angle glaucoma”, “glaucoma”, “secondary glaucoma”. A total of 19 articles related to the topic of the review were selected. The beginning of publications on this topic dates back to 2013. Results. GATT can be used at various stages of glaucoma, but at the same time, the maximum effect of lowering intraocular pressure (IOP) is achieved in patients with an early or middle stage of glaucoma. There are also good results of using the GATT technique after vitreoretinal surgery, with the development of secondary glaucoma or ophthalmic hypertension. One of the advantages of GATT is that all manipulations are performed in the anterior chamber, which in turn makes it possible, if necessary, to perform reoperation after an unsuccessful ad-externo trabeculotomy without re-traumatizing the sclera and conjunctiva. It should be noted that the main complication in all studies is the hyphema, which is completely absorbed within a few days. Conclusion. Based on these studies, it can be concluded that the proposed GATT technique is relevant, and meets all modern standards of minimally invasive glaucoma surgery (MIGS): micro-incision, minimal trauma, is able to effectively reduce IOP, has a high level of safety and quick recovery.
