Summary
Nd:YAG laser trabeculopuncture (YLT) controlled intraocular pressure in 41.7% of angle-recession glaucoma patients. Success correlated with blood reflux, and YLT is recommended for select cases with intact trabecular meshwork.
Area of Science:
- Ophthalmology
- Glaucoma Research
- Laser Therapy
Background:
- Angle-recession glaucoma presents unique challenges for intraocular pressure (IOP) management.
- Traditional treatments may have limitations in specific glaucoma subtypes.
Purpose of the Study:
- To evaluate the efficacy and outcomes of Nd:YAG laser trabeculopuncture (YLT) in patients with angle-recession glaucoma.
- To identify factors influencing the success of YLT in this patient population.
Main Methods:
- YLT was performed on 12 eyes of 12 patients with angle-recession glaucoma.
- A confluent, 1-clock-hour trabeculotomy was attempted, targeting the midtrabecular meshwork.
- Intraocular pressure (IOP) and clinical outcomes were monitored over a mean follow-up of 12.0 months.
Main Results:
- IOP was controlled (≤19 mm Hg) in 5 eyes (41.7%) post-YLT.
- Successful YLT cases showed blood reflux in all instances, unlike failed cases (28.6%).
- YLT failed in eyes with 360-degree angle recession; 50% of patients required further glaucoma surgery.
Conclusions:
- YLT can be effective in a subset of angle-recession glaucoma patients.
- The presence of blood reflux is a potential indicator of successful YLT.
- YLT is recommended for selected cases where gonioscopy reveals intact trabecular meshwork structure for Schlemm's canal penetration.
