Researchers Grow Rare Eye Vessel Cells to Halt Vision Loss

A new study demonstrates the first successful generation of retinal endothelial cells from induced pluripotent stem cells (iPSCs). When tested in vitro, the cells accurately modeled the tissue degradation of diabetic retinopathy, and when injected in vivo, they successfully integrated to regenerate damaged retinal blood vessels and restore function.

Low Income, Vision Loss, and Isolation Drive Dementia Risk

A new study reveals that people with lower incomes and those from historically underrepresented racial and ethnic groups carry a higher burden of modifiable dementia risk factors. Vision loss and social isolation were among the most significant contributors for those living below the poverty line, suggesting that better access to healthcare and community support could have major protective effects.

Scientists Identify New Gene Behind Hereditary Vision Loss

Researchers have identified a new genetic cause of hereditary optic atrophy—a condition that leads to gradual vision loss—by discovering a previously unknown mutation in the PPIB gene. This gene helps proteins fold properly and ensures healthy mitochondrial function, both of which are disrupted in affected individuals.

Hidden Early Signs of Diabetic Blindness Revealed

Scientists have developed a powerful new imaging method that reveals how immune cells in the eye behave long before visible damage occurs in diabetic retinopathy. Using a combination of a head-fixation device, contact lenses, and a custom objective lens, researchers were able to capture live, high-resolution images of microglia activity in diabetic mice.

mRNA Vaccine Targets Vision Loss in AMD

A new mRNA vaccine developed in Japan has been shown to suppress abnormal blood vessel growth in the retina of mice, offering hope for patients with age-related macular degeneration (AMD). Current treatments require repeated injections directly into the eye, but this vaccine can be delivered intramuscularly, making it less invasive and easier to administer.

Human Stem Cell Transplants Boost Vision in Advanced Dry AMD

A new clinical trial suggests stem cell therapy may restore vision in people with advanced dry age-related macular degeneration, a disease that currently has no cure. Researchers transplanted retinal pigment epithelial stem cells, derived from adult postmortem eye tissue, into patients’ eyes.

Youthful Blood Restores Aging Retina and Vision

Researchers demonstrated that systemic factors from young mice can rejuvenate the aging retina by alleviating cellular senescence and restoring function. Using heterochronic parabiosis and single-cell RNA sequencing, the study identified AdipoR1 and its downstream AMPK signaling as key drivers of retinal rejuvenation.
