Ophthalmologists are crying foul after a draft review from the federal Agency for Healthcare Research and Quality (AHRQ) questioned the effectiveness of glaucoma screening in the general and asymptomatic at-risk populations. The AHRQ review focused on screening both general and at-risk populations for open-angle glaucoma, the most common form of the disease. The analysts identified 72 primary stu

Posted by Bharat (#1) 4614 days ago (Editorial)
Diabetic retinopathy, the most common diabetic eye disease, occurs when blood vessels in the retina change. Sometimes these vessels swell and leak fluid or even close off completely. In other cases, abnormal new blood vessels grow on the surface of the retina. Diabetic retinopathy usually affects both eyes. People who have diabetic retinopathy often don't notice changes in their vision in the dis
Researchers Say as Many as 1 in 4 Preschoolers Has Vision Problem That Needs Attention
Posted by Bharat (#1) 4614 days ago (Editorial)
Vision problems among preschoolers may be more common than previously thought. That's the conclusion of researchers who conducted two large studies funded by the National Institutes of Health. Previously, it was estimated that one in 20 preschoolers had vision problems. But the studies show that as many as one out of every four preschool-aged children may have a vision problem that needs attentio
How can two brown-eyed parents give birth to a blue-eyed child?
Posted by Bharat (#1) 4614 days ago (Editorial)
The color of your eyes is determined by the genes you inherit from your parents. A gene for brown eyes is dominant. This means it over-rides genes for other eye colors. The gene for blue eyes is recessive. It shows up only when there are no genes for other eye colors. Someone with brown eyes may have a recessive, or "hidden," gene for blue eyes. Therefore, two brown-eyed parents may each give a r
Experts find root of common cause of blindness
Posted by Bharat (#1) 4619 days ago (Editorial)
Every year, millions of people around the world suffer from vision deterioration which eventually leads to blindness, and for many these conditions are incurable, resulting in their quality of life being severely impaired. However, international eye experts may have found they key to making life easier for sufferers of one blinding condition, and perhaps preventing the development of other disea
How Fetal Alcohol Syndrome affects the eyes
Posted by Bharat (#1) 4619 days ago (Editorial)
Eye doctors are interested in FAS because of the frequent involvement of the eyes, which may cause significant visual impairment in children. Visual acuity (the ability to see detail) is reduced in over 50 percent of children with FAS. Some problems such as a high refractive error (as large amount of near- or farsightedness) can be corrected with eyeglasses. Other problems that are caused by abno
Implantable Lenses: Help for Severe Myopia
Posted by Bharat (#1) 4619 days ago (Editorial)
Implanted contact lenses can now help people who have moderate to severe nearsightedness, or myopia. Called phakic intraocular lenses (IOL), these lenses are surgically implanted in the eye in front of the natural lens. They work by bending light rays onto the retina to form a clear image. Studies have found that IOL surgery is as safe as LASIK, which cuts the cornea to change its focusing power.
Keeping SCORE: Corticosteroids for Retinal Vein Occlusions
Posted by Bharat (#1) 4619 days ago (Editorial)
The Standard Care vs. Corticosteroid for Retinal Vein Occlusion (SCORE) study is the first multicenter randomized clinical trial to demonstrate the benefit of corticosteroids in managing macular edema associated with branch retinal vein occlusion (BRVO) and central retinal vein occlusion (CRVO). The SCORE-CRVO trial has significant clinical impact because it provides the first level 1 evidence t
