Effects of Green Tea Consumption on Primary Glaucoma
Sponsor: Universiti Sains Malaysia
Summary
The goal of this randomised control trial is to learn about the effect of green tea consumption 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 1 month, 3 months and 6 months who is consuming green tea compared to patient not consuming green tea? 2. Is there any difference of retina nerve fibre layer in patient with primary glaucoma after 1 month, 3months and 6 months who is consuming green tea compared to patient not consuming green tea? Researchers will compare patients with primary glaucoma who are consuming green tea and normal daily drinking to see if any affect to intraocular pressure and retina nerve fibre layer.

Patients in Group A will have to consume two cups (250ml for each cup) of hot green tea, five days per week for 6 months. A tea bag is brewed in 250ml hot water for 3 minutes. They are only allowed to consume as hot drink, not for iced tea. Any sweetener or sugar is not allowed to mix in the drink. The green tea bag will be distributed to patient at beginning of research and at every visit. Patient will be reminded weekly using text messages or phone call by a research assistant for green tea consumption.

Patients in Group B will not be consuming green tea during 6 months of study period.
