ABSTRACT
Purpose:
Description of safety and efficacy of micropulse Transscleral cyclophotocoagulation as a treatment option for refractory glaucoma.Methods:
This is a prospective study including 39 eyes of 31 patients followed for refractory glaucoma, who benefited from transscleral cyclophotocoagulation using a microplused laser. The main indication for the procedure was increased ocular pressure refractory to quadritherapy in various types of glaucoma. The patients were treated using iridex Cyclo G6 laser with a Micropulse P3 infrared probe with a wavelength of 810 ânm. The parameters for the procedure were a duration of 90 âs per hemisphere with a power of 2000 mW and an energy of 180 âJ. Both the upper and lower hemispheres were treated in the same procedure, sparing the 3 o'clock and 9 o'clock meridians, and all the patients benefited from a single treatment session. The following parameters were evaluated ocular pain and overall tolerance; visual acuity; and the evolution of IOP postoperatively up to 9 months.Results:
The glaucoma subtypes treated are as follows primary open-angle glaucoma (n â= â05), chronic angle-closure glaucoma (n â= â13), neovascular glaucoma (n â= â07), aphakic glaucoma (n â= â06), malignant glaucoma (n â= â04), post-traumatic angle recession (n â= â02), and inflammatory glaucoma (n â= â02). The mean pre-operative intraocular pressure was 42.3 â± â5.2 âmmHg and the mean post-operative intraocular pressure at 9 months was 16.9 â± â1.9 âmmHg. The reduction in IOP was 49.9%. The average number of intraocular pressure-lowering medications used prior to surgery was four, and the average number of medications used at the 9-month post-operative visit was 2.0 â± â1.2 (70.3% of patients were on dual therapy). The overall success rate was 60.5%.Conclusions:
Micropulse transscleral cyclophotocoagulation appears to be a safe and efficient treatment for refractory glaucoma. Its indications should therefore be broadened and proposed early in various situations.
