Normal Tension Glaucoma (NTG)

Pilot, single-site, prospective study of QLS-111 0.015 % in subjects with NPDR, OAG or NTG

The goal of this clinical trial is to evaluate the efficacy of direct selective laser trabeculoplasty (DSLT) or laser treatment in Asian patients with normal tension glaucoma. The main question it aims to answer is: Does the DSLT reduce intraocular pressure (IOP) and medication use in Asian NTG subjects? Participants will attend routine follow-up visits with their eye surgeon and glaucoma testing such as optical coherence tomography (OCT) imaging and visual field test(s) after the laser study treatment.

OCT-A and eco-colordoppler are technologies which enable optic nerve head (ONH) blood perfusion detection. The aim of the study is to assess ONH vascular and structural components in optic neuropathies with and without ONH edema or pseudo-edema with OCT-A, and analyze ONH blood-flow with eco-colordoppler.
