Summary
THC:YAG laser sclerostomy effectively lowered intraocular pressure (IOP) in patients with intractable glaucoma. This minimally invasive procedure offered significant IOP reduction and decreased medication needs with few complications.
Area of Science:
- Ophthalmology
- Glaucoma Research
- Laser Surgery
Background:
- Glaucoma is a leading cause of irreversible blindness.
- Intractable glaucoma often requires advanced surgical interventions.
- Traditional glaucoma surgeries can have significant complication rates.
Purpose of the Study:
- To assess the safety and efficacy of THC:YAG laser sclerostomy.
- To evaluate IOP reduction in patients with treatment-resistant glaucoma.
- To determine the long-term outcomes of this laser procedure.
Main Methods:
- 16 patients with intractable glaucoma underwent subconjunctival sclerostomy.
- The procedure was performed under a partial-thickness corneal flap.
- Intraocular pressure (IOP) and medication use were monitored at 3 and 6 months.
Main Results:
- Mean IOP decreased from 30 mm Hg to 14 mm Hg at 3 months.
- 57% of treated eyes achieved IOP below 20 mm Hg at 6 months.
- Significant reduction in glaucoma medications was observed.
Conclusions:
- THC:YAG laser sclerostomy is a safe and effective treatment for intractable glaucoma.
- The procedure provides substantial IOP reduction.
- It offers a viable alternative for patients resistant to conventional therapies.
