The Effectiveness Of Home-Based Circuit Training On Eye Pressure And Eye Nerve Structures In Patients With Glaucoma

The goal of this randomised control trial is to learn about the effect of home based circuit training on patients with primary glaucoma. The main questions to answer are: 1. Is there any difference of intraocular pressure (IOP) in patient with primary glaucoma after 6 weeks and 12 weeks who is performing home-based circuit training compared to patient not performing home-based circuit training? 2. Is there any difference of retina nerve fibre layer in patient with primary glaucoma after 6 weeks and 12 weeks who is performing home-based circuit training compared to patient not performing home-based circuit training? 3. Is there any difference of choroidal thickness layer in patient with primary glaucoma after 6 weeks and 12 weeks who is performing home-based circuit training compared to patient not performing home-based circuit training? Researchers will compare patients with primary glaucoma who are performing home-based circuit training and not performing home-based circuit training to see if any affect to intraocular pressure, retina nerve fibre layer and choroidal thickness.
