Night vision tests in age-related macular degeneration precisely localize disease mechanisms

March 17, 2023

Researchers at the University of Alabama at Birmingham discovered that night vision tests at a specific location in the retina will be suitable for assessing treatments and preventions for AMD.

Researchers discover therapeutic target to aid in glaucoma treatment

March 13, 2023

Indiana University researchers have identified a new therapeutic target that could lead to more effective treatment of glaucoma.

New insights: Eye damage in Alzheimer’s disease patients

March 3, 2023

Cedars-Sinai investigators map changes to the retina that correspond to brain changes in the early stage of Alzheimer's disease, opening a path to earlier diagnosis.

Discovery suggests new way to prevent common causes of vision loss

February 23, 2023

UVA Health scientists have discovered an unknown contributor to harmful blood vessel growth in the eye that could lead to new treatments for blinding macular degeneration and other common causes of vision loss.

Low brain pressure could be a risk factor for developing glaucoma

February 13, 2023

A recent international clinical study demonstrates that low intracranial pressure correlates with impaired patient vision, especially in the nasal zone.

HSC researcher discovered a potential cause for keratoconus

February 8, 2023

Researchers at the University of North Texas Health Science Center are the first to characterize extracellular vesicles in the tears of patients with keratoconus.

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

February 2, 2023

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.

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

January 26, 2023

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.
