Gonioscopy-Assisted Transluminal Trabeculotomy in Patients With Angle Recession Glaucoma.

Area of Science:

• Ophthalmology
• Glaucoma Surgery
• Minimally Invasive Glaucoma Surgery (MIGS)

Background:

• Angle recession glaucoma (ARG) often results from blunt ocular trauma (BOT).
• Managing uncontrolled intraocular pressure (IOP) in ARG patients can be challenging.
• Current treatment options may include antiglaucoma medications (AGM) and further surgical interventions.

Purpose of the Study:

• To evaluate the 1-year outcomes of gonioscopy-assisted transluminal trabeculotomy (GATT) in patients diagnosed with angle recession glaucoma (ARG).

Main Methods:

• A retrospective review of six eyes from six patients with ARG who had uncontrolled IOP despite AGM.
• Patients had a history of blunt ocular trauma (BOT).
• Key metrics included preoperative and postoperative IOP, number of AGM, IOP spikes, and need for further surgery.

Main Results:

• GATT, with or without phacoemulsification, significantly reduced IOP from a mean of 30.30 mmHg preoperatively to 11.95 mmHg at 12 months (P=0.028).
• All patients experienced temporary hyphema, which did not require surgical intervention.
• The number of antiglaucoma medications (AGM) decreased significantly from a median of 4.00 to 2.00 at 12 months (P=0.038).
• No patients required additional surgical interventions during the 1-year follow-up.

Conclusions:

• Gonioscopy-assisted transluminal trabeculotomy (GATT) is an effective and safe MIGS procedure for managing angle recession glaucoma (ARG).
• GATT demonstrates a successful IOP-lowering effect with low complication rates.
• GATT is a considerable surgical option for patients with ARG.
