Plasma-Assisted Filtration Glaucoma Surgery – One More Option

The aim of the study is to evaluate the surgical outcome of plasma-assisted sclerectomy surgery (PASS) in eyes with uncontrolled primary open-angle glaucoma (POAG) on maximal local antiglaucomatous therapy. PASS is a modified method of filtration glaucoma surgery.

Patients with progressive POAG received PASS treatment. We performed PASS on 12 eyes of 12 patients with open glaucoma patients. This prospective, interventional case series included patients with POAG (IOP ≥25mmHg) on maximal local therapy. We present the surgical steps of the procedure. The primary endpoint was the change in the intraocular pressure (IOP) and use of antiglaucomatous drops were investigated.

The achieved intraocular pressure (IOP) has been presented (first day, first week, 2 weeks 1 month, 3, 6 and 12 months). The filtration way has been shown by using the Anterior-segment OCT (AS OCT).

PASS procedure was found to be effective in decreasing IOP in POAG patients whose IOP was not compensated with maximal antiglaucomatous local therapy. Patients needed significantly less local therapy following the PASS.
