Researchers have discovered how molecules in glass or plastic are able to move when exposed to light from a laser. The findings could one day be used to facilitate medicinal drug distribution by allowing doctors to control the time and rate at which dr…

From eye to brain: Researchers map functional connections between retinal neurons at single-cell resolution
By comparing a clearly defined visual input with the electrical output of the retina, researchers were able to trace for the first time the neuronal circuitry that connects individual photoreceptors with retinal ganglion cells, the neurons that carry v…
Key nutrient found to prevent cataracts in salmon
New research shows how the nutrient histidine, when added to the diet of farmed salmon, stops cataracts from forming.
No difference found in drugs for macular degeneration
Researchers have conducted a study that failed to show a difference in efficacy between Bevacizumab (Avastin) and Ranibizumab (Lucentis) for the treatment of age-related macular degeneration.
Is photoscreening the best way to catch ‘lazy eye’?
Amblyopia, known as “lazy eye,” is a major cause of vision problems in children and a common cause of blindness in people aged 20 to 70 in developed countries. Pediatric ophthalmologists are looking for the best, most cost-effective ways to detect ambl…
Scarless brain surgery is new option for patients
Surgeons now suggest that transorbital neuroendoscopic surgery (TONES) is a safe and effective option for treating a variety of advanced brain diseases and traumatic injuries. This groundbreaking minimally invasive surgery is performed through the eye …
Feeding prior to eye exams reduces stress in premature infants
Premature infants are often examined for retinopathy of prematurity (ROP). This exam can be quite stressful for the neonate, causing changes in heart rate, blood pressure and oxygen saturation, and increased crying. Researchers found that, contrary to …
Six3 gene essential for retinal development, scientists show
New research adds to evidence that the Six3 gene functions like a doorman in the developing brain and visual system, safeguarding the future retina by keeping the region where the eye is forming free of a signaling protein capable of disrupting the pro…
Patients seek revision plastic surgery to correct asymmetric nasal tips, breathing obstructions
Patients who seek a second surgery to revise their rhinoplasty often do so because they are dissatisfied with the symmetry of their nasal tip and because they experience nasal obstructions, according to a new study. Surgeons who examine revision rhinop…
Tick tock: Rods help set internal clocks, biologist says
Rod cells — one of three kinds of exquisitely photosensitive cells found in the retina of the eye — are surprisingly found to be the only ones responsible for setting our internal “clocks” in low light.
Antiviral therapy associated with fewer recurring eye problems from herpes simplex virus
Taking oral antiviral medications following infection with the herpes simplex virus may be associated with a reduced risk of recurring eye-related manifestations of the disease, according a new report.
Gene discovery could yield treatments for nearsightedness
Myopia (nearsightedness) is the most common eye disorder in the world and becoming more common, yet little is known about its genetic underpinnings. Scientists have now uncovered a gene associated with myopia in Caucasian people from several different …
Brain uses eyes to pick up things: Unraveling the calculations
How does your brain know where your hand has to go to pick up a cup of coffee and successfully bring this to your mouth? By converting all of the information into coordinates of the eye, according to new Dutch research. Unraveling those calculations wi…
New neurological deficit behind lazy eye identified
Researchers have identified a new neurological deficit behind amblyopia, or “lazy eye.” Their findings shed additional light on how amblyopia results from disrupted links between the brain and normal visual processing.
Visual pattern preference may be indicator of autism in toddlers
Using eye-tracking methods, researchers have shown that toddlers with autism spend significantly more time visually examining dynamic geometric patterns than they do looking at social images — a viewing pattern not found in either typical or developme…
LEDs illuminate eye for ocular disease screening
A new imaging system using six different wavelengths to illuminate the interior of the eyeball (ocular fundus) may pave the way for doctors to easily screen patients for common diseases of the eye, such as age-related macular degeneration and diabetic …
Gene involved in Fuchs corneal dystrophy is found
A research team has found a gene likely responsible for Fuchs corneal dystrophy, an inheritable genetic disorder and leading cause of corneal transplant operations.
Seeing the world with new eyes: Biosynthetic corneas restore vision in humans
A new study from researchers in Canada and Sweden has shown that biosynthetic corneas can help regenerate and repair damaged eye tissue and improve vision in humans. The results are from an early phase clinical trial with 10 patients.
New targets for anti-angiogenesis drugs revealed
A new study describes a novel pathway of angiogenesis, the growth of new blood vessels. Targeting the new pathway, scientists identified two approaches that significantly reduced angiogenesis in mice. These discoveries may lead to novel treatments for …
Six-year-olds with squint less likely to be invited to birthday parties, study suggests
Six-year-olds with a squint are significantly less likely to be invited to birthday parties than their peers with normally aligned eyes, suggests new research.
