Circadian Fluctuations in Glaucoma

Brian Samuels, M.D., says there is an increase of eye pressure throughout the morning, and that pressure comes and goes throughout the day. This fluctuation is a known risk factor for the progression of glaucoma.

Rare Feline Genetic Disorders Identified Through Whole Genome Sequencing at MU

Whole genome sequencing (WGS), which is the process of determining an organism’s complete DNA sequence, can be used to identify DNA anomalies that cause disease. Identifying disease-causing DNA abnormalities allows clinicians to better predict an effective course of treatment for the patient. Now, in a series of recent studies, scientists at the University of Missouri are using whole genome sequencing through the 99 Lives Cat Genome Sequencing Consortium to identify genetic variants that cause rare diseases, such as progressive retinal atrophy and Niemann-Pick type 1, a fatal disorder in domestic cats. Findings from the study could help feline preservationists implement breeding strategies in captivity for rare and endangered species such as the African black-footed cat.

Current Stimulation May Keep Visual Neurons Alive After Injury – but at a Cost

In a study published in Scientific Reports, researchers from Magdeburg University (Germany) and The Chinese University of Hong Kong report that for rats and mice, repetitive transorbital alternating current stimulation (rtACS) may help preserve visual neurons from cell death after injury.

In a small and preliminary clinical trial, Johns Hopkins researchers and their collaborators have shown that an experimental gene therapy that uses viruses to introduce a therapeutic gene into the eye is safe and that it may be effective in preserving the vision of people with wet age-related macular degeneration (AMD).

Switching to a Low-Glycemic Diet May Stop Age-Related Eye Disease, Study Suggests

Led by researchers at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University, a study in mice finds that development of age-related macular degeneration (AMD) could be arrested by switching from a high-glycemic to a low-glycemic diet.

University of Birmingham Develops Revolutionary Eye Drops to Treat Age-Related Blindness

Scientists at the University of Birmingham have developed a type of eye drop which could potentially revolutionise the treatment of one of the leading causes of blindness in the UK.

The Blink of an Eye May Predict Risk for Alcohol Problems

The startle response, often recorded as an eye-blink reflex, is a defensive measure believed to reflect emotional processing. Patients with alcohol use disorders (AUDs) show abnormal startle-reflex responses to alcohol-related stimuli. This study examined startle-reflex responses to various visual stimuli among heavy drinkers, and assessed whether certain patterns predict the development of AUDs four years later.

3D-Printed Implant Helps Children Born with Small or Missing Eyes

A new, personalized and noninvasive treatment using 3-D printed implants has been developed to help children born with abnormally small or missing eyes (microphthalmia/ anophthalmia, or MICA). The research is being presented at the 2017 Annual Meeting of the Association for Research in Vision and Ophthalmology (ARVO) this week in Baltimore, Md.
