Abstract

Purpose : GATT is a minimally invasive, ab interno glaucoma surgery that has demonstrated exceptional safety and success in eyes affected by a variety of types of open angle glaucoma. This study reports outcomes of GATT in 360° using 5-0 poly-propylene instead of a microcatheter in a series of cases with primary open-angle glaucoma (POAG).

Methods : A retrospective review of all cases with POAG which underwent a GATT in 360° and phacoemulsification with intraocular lens implantation procedure by one surgeon with a follow-up of at least six months, operated in a glaucoma specialized center.

Results : The clinical information derived from the medical records of 10 eyes (10 patients) was thoroughly analyzed. Most cases were from female patients with a mean age of 69.8 ± 8.9 years. Median number of antiglaucoma medication was 2.2 ± 0.9 and a mean pre-operative IOP was 16.4 ± 4.0 mm Hg, and reduced after surgery to a median of 1.2 ± 1.2 antiglaucoma medication (p<0.02) and 11.6 ± 2.2 mm Hg of IOP (p<0.001). The most common complication was hyphema (3/10) but it was transient (lasted no more than one week). No further ocular surgery has been needed up to now.

Conclusions : Our preliminary experience with the GATT technique using poly-propylene suture as a minimally invasive glaucoma surgery seem to be safe and effective in treating POAG in this small series of cases.

This is an abstract that was submitted for the 2018 ARVO Annual Meeting, held in Honolulu, Hawaii, April 29 - May 3, 2018.
