Bioengineers at a British university have found a way to fabricate a biodegradable membrane with microscopic 3-dimensional features that protect transplanted limbal stem cells as they reepithelialize damaged corneas. In a report published online November 3, 2012, in Acta Biomaterialia, Ílida Ortega Asencio, PhD, from the Biomaterials and Tissue Engineering Group, Department of Materials Science a

Posted by Praveen (#2) 4027 days ago (Editorial)
Age-related vision changes happen to many people as they grow older. But eye problems aren't something you should simply write off as normal. Some result from new or worsening vision disorders. As age advances, these might quietly creep up on you, stealing a piece of your vision at a time. Others attack suddenly, quickly causing blindness. That is why regular eye exams with an eye doctor are so i
FDA Approves Tecnis Toric Intraocular Lens
Posted by Praveen (#2) 4027 days ago (Editorial)
The US Food and Drug Administration (FDA) has just approved Abbott's Tecnis Toric 1-piece intraocular lens (IOL) to treat preexisting astigmatism in patients with cataract. The blurry vision of corneal astigmatism derives from an irregularly curved cornea that prevents light rays from focusing sharply on the retina. Toric intraocular lenses are used to manage corneal astigmatism in patients who h
Identifying the Molecular Causes Of Vision Loss In Demyelinating Disease
Posted by Praveen (#2) 4029 days ago (Editorial)
Demyelinating diseases, such as multiple sclerosis (MS), are frequently associated with the progressive loss of vision. The retinal nerve damage is thought to be caused by immune system-mediated inflammation; however, other demyelinating disorders, such as Pelizaeus-Merzbacher disease, do not involve the immune system, suggesting that there are other causes of retinal nerve damage. Deimination i
Blood Vessels in the Eye Linked With IQ, Cognitive Function

The width of blood vessels in the retina, located at the back of the eye, may indicate brain health years before the onset of dementia and other deficits, according to a new study published in Psychological Science, a journal of the Association for Psychological Science.

OAO Reminds Ontarians of the Importance of Annual eye exams for people with Diabetes
Posted by Praveen (#2) 4029 days ago (Editorial)
The Ontario Association of Optometrists (OAO) is reminding Ontarians that routine eye examinations for people with diabetes continue to be covered by the Ontario Health Insurance Plan (OHIP) regardless of their age, and that a referral for this service is not required. A recent study published in the Canadian Medical Association Journal (CMAJ) found that when routine eye examinations for healthy
App Expands Screening for Diabetic Retinopathy
Posted by Praveen (#2) 4029 days ago (Editorial)
An app-based telemedicine program significantly increases screening for diabetic retinopathy at community health clinics, according to a multicenter randomized controlled trial. This is a more convenient form of screening than traditional surveillance by an ophthalmologist, and it is "done right in the clinic," Steven Mansberger, MD, director of glaucoma services at the Devers Eye Institute in Po

Trouble with vision makes senior living difficult for millions of Americans. In fact, according to the National Eye Institute, an estimated 1.75 million people in the U.S. have age-related macular degeneration (AMD) - the leading cause of blindness among seniors. Certain nutrients have often been seen as a good way for adults to protect their vision, and although recent research has cast doubt as
