D. Glaucoma: The Importance of Early Detection

Narrator: This is Science Today. Glaucoma is a serious condition in which the eye's internal pressure builds up, causing a blockage. If untreated, it can lead to blindness. Robert Weinreb, a professor of opthamology at the University of California, San Diego says this can be avoided if patients seek treatment early on.

Weinreb: They may be unaware of any changes in vision and at this stage, glaucoma can only be detected by the skilled eye care professional.

Narrator: Glaucoma is treated with prescription eye drops, medications and sometimes laser surgery.

Weinreb: It's recommended that anyone over the age of forty have an eye examination every two years. After the age of sixty, annually. If someone is at greater risk for having glaucoma because they have a family history, or they are African American, it's recommended that they have annual examinations after the age of thirty-five.
