Is the Reduction in IOP After Treatment of 180 Degrees Equivalent to Treatment of 360 Degrees With SLT?
NCT03529591 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 40
Last updated 2022-05-04
Summary
The study is a prospective randomised controlled intervention comparing the intraocular pressure outcomes following Selective Laser Trabeculoplasty (SLT) treatment of 180 degrees SLT compared to 360 degrees in treatment naive patients with bilateral ocular hypertension or primary open angle glaucoma . The right eye of each patient will be randomised to receive either 180 or 360 degrees SLT, while the fellow eye will receive the opposite treatment. That is, if the right eye is randomised to 180 degrees SLT, then the left eye will receive 360 degrees SLT.
The primary objective is to assess the mean difference in intraocular pressure between two eyes of each participant. The mean difference in IOP will be assessed at two weeks and at one, three and six months after treatment with SLT.
Secondary outcomes include assessing whether there are differences in visual acuity, anterior chamber inflammation, visual field progression and the rate of complications between the two eyes treated with either 180° or 360° of selective laser trabeculoplasty. The complications assessed are those published in the literature including: pain, blurred vision, anterior chamber inflammation, IOP spike, and hyphaema. Additionally, participants will be given the opportunity to report symptoms experienced through free text.

Interventions
- DEVICE
-
Selective laser trabeculoplasty (SLT)
In this study, treatment naive patients with bilateral ocular hypertension or primary open angle glaucoma are treated with 180 degrees SLT in one eye and 360 degrees SLT in the contralateral eye. The primary outcome measure is assessing the response to SLT in both eyes and comparing the intraocular pressure outcomes between the two eyes of each patient.
