MANILA -- Having unstable blood pressure can cause blindness, according to a doctor.

In an interview on "Magandang Gabi Dok" on DZMM, Dr. Edgar Leuenberger, an opthalmologist, explained that aside from affecting vital organs like the heart and the brain, hypertension can also affect the eyes.

"Ang hypertension ay isang pangkalahatang problema, at ang central axis, na palaging tinatamaan ng hypertension, ay 'yung utak, 'yung mata, 'yung puso at 'yung kidney, so nasa iisang hilera 'yan sila. At lahat sila may mga maliliit na ugat na pinagdadaluyan ng dugo," he explained.

Leuenberger explained that when a patient suffers from hypertension, the heart has to pump blood harder for it to reach the organs. Clogged arteries and veins further complicate the problem.

Although hypertension does not directly affect the eyes, sudden changes in blood pressure can cause microscopic veins in the eyes to burst, causing "eye stroke."

"Kapag tumaas ng husto ang blood pressure, maaring pumutok ang mga ugat," Leuenberger explained.

Having low blood pressure is also dangerous.

"Dahil sa sobrang blood pressure, hindi nadadala 'yung dugo sa mata, at ang mata, 24/7 kailangan ng dugo. Kung hindi makarating ang dugo sa mata, maaring magkastroke. Kung sobra, dudugo naman," Leuenberger said.

To prevent eye problems, Leuenberger suggests a healthy lifestyle and eating a balanced diet. He also urged people to avoid smoking and drinking liquor.
