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.

Conditions

  • Primary Glaucoma

Interventions

DIETARY_SUPPLEMENT

Green tean group

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.
