GATT novel 360? ab interno glaucoma procedure


Gonioscopy-assisted transluminal trabeculotomy is a circumferential trabeculotomy performed via a minimally invasive, ab interno approach. Results from follow-up of 6 to 12 months in a series of 85 adult eyes with uncontrolled glaucoma show high IOP lowering, along with a reduced need for medication.

"Suture trabeculotomy has become the gold standard for glaucoma surgery in children, and there is good evidence supporting its effectiveness in adults with primary open-angle and secondary glaucomas," said Dr Grover, attending surgeon and clinician, Glaucoma Associates of Texas, Dallas, Texas, USA.

"However, ab externo trabeculotomy is a time-consuming, relatively invasive operation that requires numerous conjunctival and scleral sutures and violates the conjunctiva so that it may preclude or diminish the success of subsequent trabeculectomy," he added.

"Our preliminary experience demonstrates that it lowers IOP and reduces medication burden equally to, if not better, than ab externo circumferential trabeculotomy, and now we look forward to analysing our results from longer follow-up," he said.
