Drinking coffee linked to glaucoma: New study tells of risk

The debate on the merits of coffee is raging on, and this time a report is saying it can affect your vision.

A Harvard study has found that people who drink three or more cups of coffee a day have a better chance of developing exfoliation glaucoma than those who do not drink it.

Medical Daily reports that exfoliation glaucoma come from tiny, white flakes building up on the lens, causing pressure inside the eye. It occurs in about 10 percent of people over age 50, and can lead to loss of vision or blindness if not treated.

The Harvard study looked at data from 78,977 women in the Nurses’ Health Study (NHS) and 41,202 men in the Health Professionals Follow-up Study who were 40 or older who did not have glaucoma, and had received eye exams between 1980 through 2008, according to Science Daily. The study took information from health questionnaires of the participants.

“If the findings are confirmed,” study author Jae Hee Kang, ScD, from Brigham and Women's Hospital in Boston said, according to Yahoo! Health, “those at risk of exfoliation glaucoma—particularly those with a family history, would be recommended to limit their intake of coffee to less than three cups per day.”

Mail Online reported that glaucoma affects 1 percent of people over 40 and about 5 percent of those over age 65. It usually develops slowly, and has no noticeable symptoms. It first affects a person’s peripheral vision.

Coffee has been found to have health advantages, depending on which study you read. It has been found to reduce risk of infections, diabetes, strokes, and breast and prostate cancer, along with providing a readable pulse for a certain segment of the population.
