An experimental treatment for blindness, developed from a patient’s skin cells, improved the vision of blind mice in a study conducted by Columbia ophthalmologists and stem cell researchers.Central vision is lost in age-related macular degeneration after cells in the retina deteriorate. New research by Stephen Tsang suggests special adult stem cells could restore sight or prevent vision loss.The

Posted by Praveen (#2) 4301 days ago (Editorial)
Uveitis is inflammation of the uvea, which is made up of the iris, ciliary body and choroid. Together, these form the middle layer of the eye between the retina and the sclera (white of the eye). The eye is shaped like a tennis ball, with three different layers of tissue surrounding the central gel-filled cavity, which is called the vitreous. The innermost layer is the retina, which senses light

Gene Linking Cataracts and Alzheimer's Disease Identified
Posted by Praveen (#2) 4301 days ago (Editorial)
In a recent study, investigators at Boston University Schools of Medicine (BUSM) and Public Health (BUSPH) identified a gene linking age-related cataracts and Alzheimer's disease. The findings, published online in PLoS ONE,

Study Underscores Importance of Early Vision Screening
Posted by Praveen (#2) 4301 days ago (Editorial)
Nearly One Third of Children in Study Had Correctable Refractive Errors. As kids head back to school or start kindergarten, it's the perfect time to make sure they have the best possible vision. A study of more than 10,000 preschoolers gives parents information on vision risks based on ethnicity and other factors and underscores the
importance of early vision screenings.

Report on Ocular Therapeutics Targeting the Retina
Posted by Praveen (#2) 4307 days ago (Editorial)
Therapies for retinal diseases are expected to overtake those for glaucoma by 2014, reports Genetic Engineering & Biotechnology News (GEN). Because current retinal disease treatments only improve vision for six to eight weeks, there is a critical need for new remedies, according to a recent issue of GEN.To see more details visit,www.me
Retinal Detachment: What Is a Torn or Detached Retina
Posted by Praveen (#2) 4307 days ago (Editorial)
The retina is the light-sensitive tissue lining the back of our eye. Light rays are focused onto the retina through our cornea, pupil and lens. The retina converts the light rays into impulses that travel through the optic nerve to our brain, where they are interpreted as the images we see.Usually, the vitreous moves away from the retina without causing problems. But sometimes the vitreous pulls
What are the Symptoms of Pinkeye, and is it Contagious?
Posted by Praveen (#2) 4307 days ago (Editorial)
Children under any suspicion of pinkeye will be quickly isolated from other children at school. The parent will be called, and the child excluded from school until they return with a doctor’s note. Granted, many types of pinkeye (conjunctivitis) are contagious. Combined with the hygiene practices of kids, pinkeye can quickly spread, especially in a preschool or day care.To see more details visit,
