Glaucoma: The 'Silent Thief' reveal Its Secrets
Glaucoma - group of diseases that damage the optic nerve is some times called as " The Silent Thief of Sight ", because it slowly damages the eyes and can cause irreparable harm before there is any vision loss. Optic Nerve is main connective nerve between brain and eye, Glaucoma damages the optic nerve that causes loss of vision.
There are treatments to delay vision loss, but no cure, making it a leading cause of blindness all over the world. It affects more than 2.7 million people in the United States and more than 60 million worldwide. There are many forms of the disease, but primary open-angle glaucoma is the most common form and the most mysterious.
"Primary open-angle glaucoma remains a black box, but researchers are pursuing many avenues to investigate the underlying causes. As we develop a better understanding of the disease process, we hope this will lead to new, more effective treatments and possibly even preventive therapies for it," said Hemin Chin, Ph.D., director of the Glaucoma and Optic Neuropathies program at the National Eye Institute (NEI), part of the National Institutes of Health.
If you've ever had an air-puff test, also known as tonometry, then you may have heard that glaucoma is linked to an increase in eye pressure, or intraocular pressure. The unique anatomy of the eye, when combined with other factors, can cause a rise in eye pressure that can in turn cause some types of glaucoma.
