Summary
Micropulse transscleral cyclophotocoagulation (MP-TSCPC) demonstrated higher success rates and less visual acuity loss compared to continuous wave transscleral cyclophotocoagulation (CW TSCPC) in glaucoma patients. Both procedures effectively reduced intraocular pressure (IOP) with minimal complications.
Area of Science:
- Ophthalmology
- Glaucoma treatment
- Surgical innovation
Background:
- Glaucoma management requires effective intraocular pressure (IOP) reduction.
- Transscleral cyclophotocoagulation (TSCPC) is a key procedure for IOP control.
- Comparing continuous wave (CW) and micropulse (MP) TSCPC techniques is crucial for optimizing patient outcomes.
Purpose of the Study:
- To compare the efficacy and safety of CW TSCPC versus MP-TSCPC.
- To evaluate outcomes in glaucoma patients with good visual acuity.
- To assess IOP reduction, success rates, and visual acuity changes.
Main Methods:
- Retrospective multicenter study involving 200 glaucoma patients.
- Patients had logMAR visual acuity <0.5 and ≥6 months follow-up.
- Surgical success defined by IOP ≤ 18 mmHg, ≥30% IOP reduction, and minimal vision loss.
Main Results:
- Both CW TSCPC and MP-TSCPC significantly reduced IOP and medication use.
- MP-TSCPC showed higher success rates (76% vs. 61% criterion A; 87% vs. 75% criterion B) at 12 months.
- Significant visual acuity loss occurred in 10% of MP-TSCPC eyes versus 20% of CW TSCPC eyes.
Conclusions:
- Both CW TSCPC and MP-TSCPC are safe and effective for IOP reduction.
- MP-TSCPC appears to offer superior success rates and better visual acuity preservation.
- Further research may refine the choice of TSCPC technique based on patient profiles.

01:28Angle Closure Glaucoma: Treatment
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
01:27Open Angle Glaucoma: Treatment
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
