Retina
-
For the first time, scientists have identified a marker in the retina that may lead to Parkinson’s disease, and it can be detected early, which could be life-changing for those at risk of developing this or other degenerative conditions.

This stunning image may look like a particularly lively Jackson Pollock painting, but it’s actually an example of a new cell imaging technique. The subject? A human retina.
-
A new technique may one day help restore sight to patients with inherited vision impairment. The regenerative therapy works by expressing genes that convert dormant cells into new light-sensing cells in the retina to replace those lost to disease.
-
Scientists have grown mini eyes from human cells in the lab. These eye organoids provide good models of the real thing to help scientists study diseases that cause blindness and potentially find treatments.
-
A team of researchers in the UK has developed a fully automated artificial intelligence-enabled system that can scan retinal images for vascular health, helping identify those at high risk of heart disease and stroke.

Autism and ADHD are becoming better understood, but clinicians can still find the two conditions difficult to tell apart. Now, South Australian researchers say they've produced evidence that the two conditions could be diagnosed using an eye test.
-
Scientists in Europe have discovered a molecular “zipper” mechanism that can lead to cell death in the genetic disease retinitis pigmentosa. The good news is that injecting certain proteins could slow or prevent vision impairment from the disease.
-
Scientists have found that an existing drug, already used in humans, could help restore vision lost to conditions like age-related macular degeneration and retinitis pigmentosa. The discovery could also lead to a whole new class of drugs.
-
Researchers have built an artificial retina out of perovskite materials that can detect light in a similar fashion to the human eye. In tests, the device was even able to recognize handwritten numbers with a high degree of accuracy.
-
A team at the University of Wisconsin-Madison has engineered a novel type of scaffold that could give efforts to tackle vision loss a boost, by improving the precision with which replacement photoreceptor cells can be delivered into the eye.
-
Glaucoma can cause vision loss that's currently irreversible. But now scientists have found that removing a membrane in the eye could help transplanted cells migrate into the optic nerve and repair the connections, potentially restoring lost vision.
-
Spanish researchers have created a new potential treatment for age-related macular degeneration, which is currently untreatable – a biohybrid artificial retina, made of silk and loaded with new human cells that can integrate and repair the damage.
