Summary

The use of Cyclodestruction procedures has been extended to patients with non-refractory glaucoma and good vision. Our aim is to compare the safety and efficacy of three cyclodestructive treatments; High Intensity Focused Ultrasound (HIFU) Cyclocoagulation versus micropulse cyclophotocoagulation (MP-CPC) versus transscleral continuous wave cyclophotocoagulation (CW-CPC) for the treatment of Primary open angle glaucoma.

Conditions

  • Primary Open Angle Glaucoma

Interventions

PROCEDURE

Cyclophotocoagulation

High Intensity Focused Ultrasound Cyclophotocoagulation (HIFU): parameters: 21 MHz frequency, 2.45 W acoustic power, with the activation of each transducer lasting 6 seconds MicroPulse cyclophotocoagulation (MP-CPC):Laser settings of 2 Watts (W) will be applied for a 90 seconds treatment time for each 180 degrees, with a duty cycle of 31.3%, which consists of 0.5ms "on time" and 1.1 ms "off-time" and delivering a total of 112,7 Joules Continuous Wave cyclophotocoagulation (CW-CPC): The laser settings used will be 1.250 W, 4s exposure time per burn, 22-24 burns per eye.
