Glaucoma 1, Open Angle, D

This study compares two laser treatments for open-angle glaucoma: Selective Laser Trabeculoplasty (SLT) and Direct Selective Laser Trabeculoplasty (DSLT). SLT is a widely used procedure that requires a manual technique with a goniolens, while DSLT is a new, automated, non-contact method using the Eagle system. The study will evaluate whether DSLT is as effective as SLT in reducing intraocular pressure (IOP). Participants will be randomly assigned to receive either treatment and will be monitored over 12 months to assess changes in IOP, medication use, and safety outcomes. The goal is to determine if the simpler DSLT procedure can provide similar results to SLT, potentially improving patient comfort and access to glaucoma care.

The goal of this clinical trial is to learn if a new contact lens device can record patterns in eye pressure for 24 hours in adults with glaucoma and in healthy participants.
The main questions it aims to answer are:
* Is the contact lens device able to detect patterns in eye pressure that happens naturally between nighttime and daytime?
* Are the contact lens recording patterns similar when repeated one week later?
* What eye problems do participants have when wearing contact lens for up to 24 hours?
Researchers will compare if the recordings detected by the contact lens over 24 hours are similar to the patterns measured by an eye pressure measuring instrument used in a doctor's office.
Participants will
* Wear contact lens in one eye for up to 24 hours
* Take recordings in that eye with smartphone camera every 15 minutes when awake
* For those participants who are able to stay overnight at a hotel for the trial, researchers will measure the eye pressure in the other eye every 1 to 2 hours when awake with an eye pressure measuring instrument.

The aim of this study is to examine whether there is a difference in macular ganglion cell complex thickness and retinal nerve fiber layer thickness in early-stage Primary open angle glaucoma and normal tension glaucoma with spectral domain OCT.
