Micropulse Versus Continuous Wave Transscleral Cyclophotocoagulation in Refractory Pediatric Glaucoma

Area of Science:

• Ophthalmology
• Pediatric Glaucoma Treatment
• Surgical Interventions

Background:

• Refractory glaucoma in children presents significant management challenges.
• Transscleral cyclophotocoagulation is a treatment option for advanced pediatric glaucoma.
• Comparing different modes of cyclophotocoagulation is essential for improving patient outcomes.

Purpose of the Study:

• To compare the safety and efficacy of micropulse cyclophotocoagulation (MP-CPC) versus transscleral continuous wave cyclophotocoagulation (CW-CPC).
• To evaluate outcomes in pediatric patients with refractory glaucoma undergoing these procedures.

Main Methods:

• A prospective study involving 45 eyes of 36 children with refractory glaucoma.
• Eyes were treated with either MP-CPC or CW-CPC transscleral cyclophotocoagulation.
• Outcomes assessed included intraocular pressure (IOP) reduction, success rates (IOP 5-21 mmHg at 6 months), and complications.

Main Results:

• Both MP-CPC and CW-CPC effectively reduced IOP, with reductions of 63% and 67% respectively.
• The success rate was higher in the MP-CPC group (71%) compared to CW-CPC (46%), though not statistically significant.
• The MP-CPC group experienced no significant complications, while the CW-CPC group had cases of phthisis bulbi, severe pain, and uveitis.

Conclusions:

• Both MP-CPC and CW-CPC are effective for lowering IOP in pediatric refractory glaucoma.
• MP-CPC appears to be a safer alternative due to a lower rate of complications, pain, and inflammation.
• MP-CPC may be preferred, especially considering the frequent need for retreatment in pediatric glaucoma management.
