Glaucoma News and Research RSS Feed - Glaucoma News and Research

While there are many causes of glaucoma, most cases are associated with increased intraocular pressure. Loss of vision is usually characterized by a gradual reduction in peripheral vision, which can lead to a tunnel vision effect. Glaucoma affects approximately 100 million people globally and is one of the leading causes of blindness in the world today. An estimated three million Americans have this sight-threatening disease. Because it is painless and advances gradually, many people who have glaucoma or elevated IOP have not been diagnosed. If detected and treated early, vision can usually be preserved.

NIH-funded study finds visual impairment, blindness may double by 2050

With the youngest of the baby boomers hitting 65 by 2029, the number of people with visual impairment or blindness in the United States is expected to double to more than 8 million by 2050, according to projections based on the most recent census data and from studies funded by the National Eye Institute, part of the National Institutes of Health.

Comprehensive dilated eye exams may provide clear view of eye health

Comprehensive dilated eye exams may provide clear view of eye health

David Watson has worn glasses to correct nearsightedness the majority of his life, and had his vision checked regularly to make sure his prescription was up to date. But when his wife convinced him to have a comprehensive dilated eye exam, he got a surprise. His doctor told him something didn't look right with his retina, the light sensitive tissue at the back of his eye. His retina was torn, and he had not had any symptoms. [More]

A University of Iowa-led study of diabetes-related vision impairment holds good news -- and some bad news -- for patients with signs of these disorders. [More]

New methods for IOP measurements in patients with abnormal corneas

As a fundamental component of the ocular examination, accurate measurement of intra-ocular pressure (IOP) facilitates the management of patients with established glaucoma and the identification of patients with an elevated risk of developing glaucoma. For over 70 years, the most common method of measuring IOP has been by Goldmann Applanation Tonometry (GAT), largely on account of its low cost and ease of use. [More]

Research suggests new pathway for preventing optic nerve damage in KPro recipients

Researchers from Massachusetts Eye and Ear/Harvard Medical School have identified inflammatory factors that cause optic neuropathy in the back of the eye following implantation of a keratoprosthesis (KPro) — similar to what glaucoma patients experience, without the rise of pressure in the eye — and have shown that blocking one of those factors, tumor necrosis factor alpha (TNFa), successfully halts the development of optic nerve damage in a mouse model.
