Proteins-Transport Discovery New Strategies For Treating Vision Loss

Many forms of vision loss stem from a common source: impaired communication between the eye and the brain. And at the root of all eye-to-brain communication are the hundreds of proteins generated by the retina’s nerve cells. A new study from Scripps Research, which appears this month in Cell Reports, examines these proteins in unprecedented…

Shedding Light On How The Human Eye Perceives Brightness

Japanese scientists are shedding new light on the importance of light-sensing cells in the retina that process visual information. The researchers isolated the functions of melanopsin cells and demonstrated their crucial role in the perception of the visual environment. This ushers in a new understanding of the biology of the eye; and how visual information…

Diabetic Retinopathy

Deep Learning Model Detects Diabetic Retinopathy Accurately

Diabetic retinopathy is the most common microvascular complication in diabetes; for the screening of which the retinal imaging is the most widely used method due to its high sensitivity in detecting retinopathy. The evaluation of the severity and degree of retinopathy associated with a person having diabetes; currently performed by medical experts based on the…

Patients Recall Few Suggestions For Contact Lens Wear, Care

An estimated 45 million U.S. residents enjoy the benefits of contact lens wear; but many of them might be at increased risk for complications stemming from improper wear and care behaviors. One of the most serious complications of contact lens wear is a corneal infection known as microbial keratitis; which can sometimes result in reduced…

New Insight On The Functioning Of The Eye And Retinal Diseases

Finnish researchers have found cellular components in the epithelial tissue of the eye; which have previously thought to only be present in electrically active tissues; such as those in nerves and the heart. A study at Tampere University found that these components; voltage-gated sodium (Nav) channels; involved in the renewal of sensory cells in the…

Unused Pharmaceuticals Common After Cataract Surgery

Unused pharmaceutical products during phacoemulsification result in relatively high financial and environmental costs; according to a study published online in JAMA Ophthalmology. Pharmaceutical products, including unused portions; may contribute to financial and environmental costs in the United States. Because cataract surgery, performed millions of times each year in the United States and throughout the rest…

Major Breakthrough In Understanding Common Eye Disease

Scientists at Trinity College Dublin have announced a major breakthrough with important implications; for sufferers of a common eye disease dry Age-Related Macular Degeneration (AMD) – which can cause total blindness in sufferers; and for which there are currently no approved therapies. Age-related macular degeneration (AMD) is the leading cause of central retinal vision loss…

Pupillary Response To Glare Illusions Of Different Colors

Pupil contraction also known to occur when people view a brightness illusion. This study involved showing glare illusions to subjects in a variety of different colors; and conclude that a blue glare illusion, perceive to be the brightest among all the colors and that subjects’ pupils constricted significantly in relation to this perception. The results…

Emergency Eye Care

Quicker Treatment Times From Emergency Eye Care Trial

The tele-ophthalmology system, developed by the University of Strathclyde and by NHS Forth Valley; uses a live video feed to securely connect doctors, opticians and patients. Using a mixture of 3-D printed technology developed at Strathclyde; combined with the Scottish Government funded Attend Anywhere Video Consultation Platform, eye doctors can remotely examine patients in emergency…

Myopia

Myopia Is Less In Children Who Spend Time Outdoors

“At night we become a five-star hotel,” said assistant professor Ostrin; good humoredly explaining part of her $1.8 million research grant, sponsored by the National Eye Institute. The goal is to find why an ever-increasing number of youngsters need glasses and, specifically; if exposure to specific types of light might prevent myopia, or nearsightedness. At…

Eye-On-A-Chip

Blinking Eye-On-A-Chip Used For Disease Modeling And Drug Testing

People who spend eight or more hours a day staring at a computer screen may notice their eyes becoming tired or dry; and, if those conditions are severe enough; they may eventually develop dry eye disease (DED). DED is a common disease with shockingly few FDA-approved drug options; partially because of the difficulties of modeling…
