The Proceedings of the National Academy of Sciences (PNAS) reports a major breakthrough by two Weill Cornell Medical College researchers in the longstanding efforts of restoring sight. The team managed to decipher the retina's neural code from a mouse and coupled this information to a novel prosthetic device to restore sight to blind mice. They report that they have also deciphered the code for a

An ocular migraine (also called an "ophthalmic migraine," "optical migraine" or "migraine aura") produces this disturbed vision, with or without an accompanying headache. Changes in blood flow to the brain are thought to be the cause. The visual distortion starts in the center of the field of vision. It might appear as a bright dot, dots, or a line that can seem to move and disrupt your ability t
Post- Surgical Scarring for Glaucoma Patients R educe by Breakthrough Treatment
Posted by Bharat (#1) 4342 days ago (Editorial)
Scientists at the Singapore Eye Research Institute (SERI) and Nanyang Technological University (NTU) have developed an innovative way to combat post-surgical scarring for glaucoma patients. A clinical trial has shown that the use of a new drug delivery method has resulted in 40 per cent fewer injections needed by glaucoma patients to prevent scarring after surgery. This also means fewer hospital
Researcher's Fish-Eye View Could Offer Insights For Human Vision
Posted by Bharat (#1) 4342 days ago (Editorial)
Zeran Li, as an undergraduate student in biological sciences, led a research team that uncovered an enzyme's role in the regulation of eye size in the fish. If the enzyme's role is similar in human eyes, it could be relevant to human vision problems, such as nearsightedness and farsightedness. “New insights into the process of eye-size control in zebrafish may help our understanding of the regula
Special needles developed to deliver drugs through the eye
Posted by Bharat (#1) 4342 days ago (Editorial)
A new development has been made for delivering drugs into the eyes. The new process uses tiny ‘microneedles’ to inject drugs into the eyeball.A team of researchers based at the Georgia Institute of Technology and Emory University, in the US, have demonstrated that drugs can be successfully delivered to the eye using microneedles. Injections into the eye are known as intravitreal injections. Injec
Consumers Overconfident About Eye Health

People around the world are ignorant about eye care, a new study shows, but they think they are knowledgeable. The result is risky behaviors and neglect that could endanger not only vision but also overall health, according to a survey funded by Bausch + Lomb, the eye-care device and pharmaceutical giant. The Barometer of Global Eye Health, sponsored by Bausch + Lomb and conducted by the marketin
Playing outside reduces short-sightedness
Posted by Bharat (#1) 4344 days ago (Editorial)
Researchers from the universities of Bristol and Cardiff have found that children who spend more time outdoors playing when they are aged between eight and nine are approximately half as likely to become short-sighted by the time they are 15.The symptoms of short-sightedness, also known as myopia, often start around puberty. Things in the distance appeared blurred. Glasses, contact lenses or othe
Leber Congenital Amaurosis Type 18 Gene Identified
Posted by Bharat (#1) 4344 days ago (Editorial)
Four independent research teams have described mutations in a gene known for its role in energy metabolism as the cause of the 18th recognized form of Leber congenital amaurosis (LCA), the most common type of childhood blindness.The discovery, described in 4 articles published online July 29 in Nature Genetics, provides a starting point for developing treatments. Another form of LCA, caused by mu
