Retinal Nerve Thinning May Predict Cognitive Decline

Individuals with a thinner retinal nerve fiber layer were twice as likely to experience cognitive decline over 3 years, a large study has found. The researchers included more than 30,000 UK adults (aged 40 to 69) and found that people with the thinnest retinas were 11% more likely to fail…Continue readingRetinal Nerve Thinning May Predict Cognitive Decline

Key Parkinson’s Biomarker Can Be Detected In The Retina

Build-up of a protein known as alpha-synuclein in the retina is a key Parkinson’s biomarker that could help detect the degree of severity of the disease, a new study notes. The work, part of a broader scientific project funded by the Michael J. Fox Foundation, was led by Dr. Nicolás…Continue readingKey Parkinson’s Biomarker Can Be Detected In The Retina

Infants Strong Pupillary Light Reflex Linked To Later Autism Diagnosis

Infants who are later diagnosed with autism spectrum disorders react more strongly to sudden changes in light, a new study indicates. The finding lends support to the view that sensory processing plays an important role in the development of the disorder. Despite being defined by symptoms in social communication, researchers…Continue readingInfants Strong Pupillary Light Reflex Linked To Later Autism Diagnosis

Electrical Synapses Drive Retinal Feature Selectivity

Two types of cells have been found in the retina that determine horizontal or vertical orientation, Northwestern Medicine scientists report. They have also demonstrated for the first time how they convey information. The laboratory of Gregory Schwartz, Ph.D., assistant professor of Ophthalmology and Physiology, investigates the retina, a layer of…Continue readingElectrical Synapses Drive Retinal Feature Selectivity

Eardrum Motion Synchronized With Direction And Amplitude Of Saccades

Moving the eyes triggers the eardrums to move as well, a new study by Duke University neuroscientists has found. The researchers discovered that keeping the head still but shifting the eyes to one side or the other sparks vibrations in the eardrums, even in the absence of any sounds. Surprisingly,…Continue readingEardrum Motion Synchronized With Direction And Amplitude Of Saccades

Melanopsin Stimulation Produces A Distinct Perceptual Experience

The reflexive system of the human eye also produces a conscious, visual experience, according to a new study from researchers in the Perelman School of Medicine and School of Arts and Sciences at the University of Pennsylvania. The findings may provide insight into the excessive light sensitivity sometimes experienced by…Continue readingMelanopsin Stimulation Produces A Distinct Perceptual Experience

New Gene Therapy Gives Hope To People With Inherited Eye Disorder

The first successful gene therapy for an inherited form of blindness was recently reviewed by an expert panel of advisers at US Food and Drug Administration (FDA). They unanimously voted in recommendation of the treatment. The FDA now has until January 12, 2018 to approve the treatment. Spark Therapeutics, an…Continue readingNew Gene Therapy Gives Hope To People With Inherited Eye Disorder
