Beat glaucoma with TEA

Share

Glaucoma causes fluid pressure to build up inside the eye (intraocular pressure), damaging the optic nerve.

A new study has found that drinking a cup of tea at least once a day can reduce the risk of Glaucoma in a person. The condition now affects 57.5 million people across the world, making it a leading cause for blindness worldwide.

The new findings show that lifestyle changes could help prevent vision loss from glaucoma, lead study author Anne Coleman of the University of California, Los Angeles, was quoted as saying by Live Science.

Previous research suggests that caffeine can alter intraocular pressure, but no study so far has compared the potential impact of decaffeinated and caffeinated drinks on glaucoma risk.

Published in the British Journal of Ophthalmology, researchers in the USA looked at the results of eye examinations from 1,678 participants aged 40 or over, as well as analysing data from a 2005-200 nationwide health and nutrition survery.

The survey used a range of tools, including interviews, physical examinations, and blood samples, aiming to give a detailed pictured of health in the United States population.

The survey also included tests for Glaucoma, in which 5 percent adults out of 1,678 participants had developed the disease.

Recently, scientists from Brown University in Providence, RI, and the University of California in Los Angeles have made a decision to compare how the consumption of various drinks - including hot tea, decaffeinated tea, iced tea, coffee, and soft drinks - influence the risk of glaucoma.

The researchers found that hot tea drinkers were 74 per cent less likely to have glaucoma.

However, according to the researchers, tea contains antioxidants as well as anti-inflammatory and neuroprotective chemicals, which are linked with a decreased risk of serious conditions like heart disease, cancer, and diabetes.

However, the researchers noted that this was an observational study, and therefore, no firm conclusions can be drawn about cause and effect.

That being said, the researchers accept that there are limitations in the study including a lack of data on the type of tea drunk, possible errors in diagnosis and the fact that very few participants had glaucoma.

Other missing information refers to how much of the beverage the hot tea drinkers actually had each day, what kind of tea they consumed, and how it was brewed, which may have swayed the findings.
