Gonioscopy-Assisted Transluminal Trabeculotomy in Angle Recession Glaucoma

Area of Science:

• Ophthalmology
• Glaucoma Surgery
• Ocular Trauma

Background:

• Angle recession (AR) following blunt ocular trauma can lead to elevated intraocular pressure (IOP).
• Medical management with multiple antiglaucoma agents is often insufficient for controlling IOP in AR.
• Surgical interventions are necessary when medical therapy fails.

Observation:

• A 53-year-old male presented with severe IOP (38 mm Hg) in the left eye due to AR after blunt trauma.
• The patient was already on four antiglaucoma medications without adequate IOP control.
• Gonioscopy-assisted transluminal trabeculotomy (GATT) was performed.

Findings:

• Immediate postoperative IOP dropped significantly to 10 mm Hg.
• Sustained IOP control was achieved at 18 mm Hg one year after GATT.
• The patient no longer required antiglaucoma medications post-surgery.

Implications:

• GATT is a viable and effective surgical option for managing angle recession.
• This case report highlights GATT as a potentially first-line surgical treatment for AR.
• Further studies are warranted to confirm GATT's efficacy in a larger cohort of AR patients.
