In a new study, a light-sensitive moiety has been added to propofol, a commonly used anesthetic, allowing its narcotic effect to be controlled by light. The compound also offers a possible route to the treatment of certain eye diseases. Inhibitory neurotransmitters dampen the activity of neurons.This regulatory effect forms the basis for the action of many anesthetics.For example, propofol, a com

Optometrists are calling on people to take better care of their eyes after research found that almost one in 10 people have not had an eye test in the last decade. The College of Optometrists said that 9% of British adults cannot remember the last time they had a test or claim that it has been at least 10 years since they visited an optician. Many people said they had not been for a test because
'Real World' Trial of Ranibizumab Raises No Safety Signals
Posted by Praveen (#2) 4297 days ago (Editorial)
A large trial of ranibizumab (Lucentis, Novartis) for wet age-related macular degeneration (AMD) has shown no new safety signals.Patients received an average of 4 to 6 injections over 12 months and had a visual acuity gain of 7 letters.The first of 4 planned yearly updates of the ongoing LUMINOUS trial were presented here at the 12th EURETINA Congress; it is expected that the final results will b
Cholesterol-Lowering Drugs May Be Linked to Increased Cataract Risk
Posted by Praveen (#2) 4297 days ago (Editorial)
Patients using cholesterol-lowering statin drugs may be at increased risk of developing age-related cataracts, according to a study. Statins and Diabetes Both Increase Cataract Risk The study included nearly 6,400 patients seen at the optometry clinic at the University of Waterloo in 2007-08. Of these, 452 patients had type 2 diabetes. Statin treatment and diabetes were evaluated as possible risk
Stem Cell Improve Visual Function in Blind Mice
Posted by Praveen (#2) 4297 days ago (Editorial)
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
What Is Uveitis?
Posted by Praveen (#2) 4297 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) 4297 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,
contribute to the growing body of evidence showing that these two diseases, both associated with increasing age,may share common etiologic factors.To see more details visit,
