the Pops-titration Versus the Slow-coagulation Cyclophotocoagulation in Treatment of Refractory Glaucoma

Overview

* Transcleral cyclophotocoagulation (TSCPC) has long been used as refractory glaucoma management and is very easy to learn and easy to perform. * Recent advances in laser technology; the role of TSCPC is being expanded because it has benefits of noninvasive glaucoma procedure. * The titration (pops), the fixed high-energy, and the fixed-low energy (slow-coagulation) are three energy delivery techniques. * The present study would report on the outcome (efficacy and safety) of the slow-coagulation versus the titration method in treatment of refractory glaucoma with dark iris. * The results would provide reliable evidences to supplement clinical judgment when making a decision in favor of each treatment method for glaucoma patients.

* Several protocols afford delivery of the "optimum" dose of laser energy per session necessary to achieve a long-term effective ocular hypotensive response balancing risks related to a high energy treatment and risks related to retreatment due to suboptimum dose delivery. * There are two main approaches to delivering laser energy, the pops-titration method and the fixed energy method that are the fixed-high and low-energy (the Gaasterland's slow-coagulation technique). * Of particular interest is which laser energy delivery method (slow-coagulation versus pops-titration) affords the optimal dose of photocoagulation necessary to achieve an effective long-term intraocular pressure (IOP) reduction while minimizing the risk of adverse events related to overtreatment and retreatments especially in refractory glaucomatous eyes with dark iris color.
