TV Viewing Could Reveal Symptoms of Glaucoma
Published at
Hemera/Thinkstock(LONDON) — How you watch TV could indicate whether you’re suffering from the debilitating eye disease glaucoma.
That’s according to City University London Professor David Crabb, who says that glaucoma, a disease affecting 65 million people worldwide, can be detected by a map of eye movements during the viewing of a movie.
Crabb and his team studied a group of elderly people with both healthy vision and those diagnosed with glaucoma as they watched TV and film clips.
Through a device that tracked eye movements, researchers were able to verify those with unaffected vision and the others with glaucoma, which causes loss of peripheral vision and in some cases, blindness.
Crabb says that although more testing needs to be done, this way of diagnosing glaucoma could help get people treatment early since once the damage is done to the eyes, it cannot be reversed.
