Synapses between neurons in thalamus and cortex.

Sparse, small, but diverse neural connections help make perception reliable, efficient

In a study from the Picower Institute at MIT, the first detailed mapping and modeling of thalamus inputs onto visual cortex neurons show brain leverages “wisdom of the crowd” to process sensory information.

US-Mexico Symposium highlights international collaborations, diabetic eye disease research

Session topics included assessing the global burden of diabetes-related eye disease; preventing, treating, and managing disease; and collaborating internationally.
A person with diabetes checks their blood sugar

Researchers unravel why episodes of low blood sugar worsen eye disease in people with diabetes

Researchers at Johns Hopkins Medicine say they have linked transient low blood sugar levels that occur in people with diabetes with a molecular pathway that is turned on in oxygen-starved cells in the eye.

Small creatures teach big lessons

In the vision field, researchers turn to a variety of small, non-mammalian animal models to help bridge gaps in our scientific knowledge.

Type 1 diabetes: Maintaining the enzyme ACE2 in the gut prevents diabetic blindness

Study from University of Alabama at Birmingham suggests that a leaky small intestine that weakens the barrier between gut bacteria and the blood system may drive diabetic retinopathy.
Eye with coloboma

Zebrafish model helps explain eye development

Developed by NIH scientists, the model also sheds light on developmental eye disorders such as coloboma.

Nanotechnology may improve gene therapy for blindness

Using nanotechnology that enabled mRNA-based COVID-19 vaccines, a new approach to gene therapy may improve how physicians treat inherited forms of blindness.

Lab-grown retinal eye cells make successful connections, open door for clinical trials to treat blindness

Retinal cells grown from stem cells can reach out and connect with neighbors, according to a new study, completing a “handshake” that may show the cells are ready for trials in humans with degenerative eye disorders.
Green-stained limbal stem cells track towards center of mouse cornea.

Dry eye disease alters how the eye’s cornea heals itself after injury

Studying mice, researchers at Washington University School of Medicine in St. Louis have found that proteins made by stem cells that regenerate the cornea may be new targets for treating and preventing corneal injuries in people with dry eye.

SUNY Optometry receives grant to reveal cellular and molecular mechanisms affecting myopia development

Myopia is a leading cause of vision impairment worldwide and is growing in prevalence, this study aims to provide a deeper understanding of the biology of myopia that will lead to new and more effective treatments.
