Zinc in the Retina May Indicate A New Way to Protect and Regenerate the Optic Nerve in Glaucoma Patients

Connecting pieces of information by finding a common thread often takes glaucoma researchers in unexpected directions. Zinc is one such thread that joined together different experts at Boston Children’s Hospital and Harvard Medical School.

Brain “Rewires” Itself to Enhance Other Senses in Blind People

The brains of those who are born blind make new connections in the absence of visual information, resulting in enhanced, compensatory abilities such as a heightened sense of hearing, smell and touch, as well as cognitive functions (such as memory and language) according to a new study led by Massachusetts Eye and Ear researchers.

Study Suggests New Way to Prevent Vision Loss in Diabetics and Premature Babies

Researchers at Bascom Palmer Eye Institute, part of the University of Miami Miller School of Medicine, have identified a new molecule that induces the formation of abnormal blood vessels in the eyes of diabetic mice. The study, “Secretogranin III as a disease-associated ligand for antiangiogenic therapy of diabetic retinopathy,” which will be published March 22 in The Journal of Experimental Medicine, suggests that inhibiting this molecule may prevent similarly aberrant blood vessels from damaging the vision of not only diabetics, but also premature infants.

ARVO Opposes Cuts to Medical Research Budget; Urges Increased Investment

The Association for Research in Vision and Ophthalmology (ARVO) urges Congressional leaders to reject the U.S. administration’s recent FY18 budget proposal, which seeks to drastically cut National Institute of Health funding by nearly $6 billion, or 20%. These cuts would be devastating to the current and future efforts of the eye and vision research community and to patients who desperately count on the efforts of researchers and clinicians to save their sight.

Researchers at the University of Illinois at Chicago College of Medicine and Massachusetts Eye and Ear/Harvard Medical School have developed a cheap, portable camera that can photograph the retina without the need for pupil-dilating eye drops.

A study published recently in the journal Psychology and Behavior unveils the potential to use changes in saccadic eye movements - the rapid repositioning of the eye to focus on a target - as a reliable biomarker for pilot fatigue. Professors Stephen Macknik, PhD, and Susana Martinez-Conde, PhD of SUNY Downstate Medical Center were co-authors in the study.

NIH-Funded Scientists Deploy CRISPR to Preserve Photoreceptors in Mice

Silencing a gene called Nrl in mice prevents the loss of cells from degenerative diseases of the retina, according to a new study. The findings could lead to novel therapies for preventing vision loss from human diseases such as retinitis pigmentosa. The study was conducted by researchers at the National Eye Institute (NEI), part of the National Institutes of Health, and was published online today in Nature Communications.

A team of engineers at the University of California San Diego and La Jolla-based startup Nanovision Biosciences Inc. have developed the nanotechnology and wireless electronics for a new type of retinal prosthesis that brings research a step closer to restoring the ability of neurons in the retina to respond to light. The researchers demonstrated this response to light in a rat retina interfacing with a prototype of the device in vitro.

Breast Cancer Drug Dampens Immune Response, Protecting Light-Sensing Cells of the Eye

The breast cancer drug tamoxifen appears to protect light-sensitive cells in the eye from degeneration, according to a new study in mice. The drug prevented immune cells from removing injured photoreceptors.
