Micropulse Transscleral diode laser cyclophotocoagulation (MP-TSCPC) is an established method of treatment for refractory glaucoma. This study evaluates the efficacy in terms of reduction in intraocular pressure and/or treatment amount, and safety and side effects of the ciliary bodies using a subthreshold laser with a duty cycle of 31.3% with Supra 810 nm Subliminal Quantel Medical, at one year in patients with refractory glaucoma.

Micropulse Transscleral Cyclophotocoagulation (MP-TSCP) is a recently developed cyclodestructive procedure less aggressive than conventional TSCP. In this study, we aimed to evaluate the safety and efficacy of MP-TSCP in a real-life setting.

In recent years, the glaucoma treatment marketplace has been inundated with new laser technologies, which have excited physicians and surgeons as they have completely reinvented and invigorated the glaucoma treatment paradigm. Today, glaucoma is on the rise and continues to be one of the leading causes of blindness and vision loss worldwide.

Origins of surgical glaucoma treatment date
back to the mid 1800s when iridectomy was discovered as an effective surgical method for the treatment of acute glaucoma and sclerotomy was presented as a procedure for chronic glaucoma. Though advancements have continued to change the landscape of how to treat glaucoma, the approaches remain largely the same: relief of the pupillary block, external filtration, internal filtration, and ciliodestruction.

The objective of this study was to compare the effectiveness and the tolerance of SS-TSCPC with a duty cycle of 25% versus 31.3% with Supra 810 nm Subliminal Quantel Medical laser stimulation for advanced glaucoma.
