Humans develop sharp vision during early fetal development thanks to an interplay between a vitamin A derivative and thyroid hormones in the retina, Johns Hopkins University scientists have found. The findings could upend decades of conventional understanding of how the eye grows light-sensing cells and could inform new research into treatments for macular degeneration, glaucoma, and other age-related vision disorders. Details of the study, which used … Read more
Doctors have found that metformin, an everyday medicine for diabetes, is associated with less progression of age-related macular degeneration (AMD), the commonest cause of blindness in western countries. People with diabetes over the age of 55 years taking metformin were 37% less likely to develop the intermediate stage of AMD over a five year period … Read more
A breakthrough study shows that a daily oral dose of 8-aminoguanine could safeguard retinal health and slow vision loss in aging, opening new avenues for treating degenerative eye diseases. Study: Oral 8-aminoguanine against age-related retinal degeneration.

National Institutes of Health (NIH) scientists have developed a new surgical technique for implanting multiple tissue grafts in the eye’s retina. The findings in animals may help advance treatment options for dry age-related macular degeneration (AMD), which is a leading cause of vision loss among older Americans. A report about the technique published today in … Read more
A recent cross-sectional analysis of National Health and Nutrition Examination Survey (NHANES) data conducted in Tianjin revealed that the systemic inflammatory response index can be used to successfully identify age-related macular degeneration (AMD). “These findings suggest that [the index] could be used as a biomarker for AMD risk assessment, which can greatly benefit patient care,” … Read more
A recent prospective cohort study conducted in Hong Kong revealed a substantial linkage between simultaneous exposure to multiple air pollutants and age-related eye disease incidence. “Given that individuals are exposed to a complex mixture of air pollutants and that high collinearity exists among different pollutants, estimating the combined effect of multiple air pollutants on human … Read more
A new research paper was published in Aging (Aging-US) on January 31, 2025, in Volume 17, Issue 2, titled “Cysteinyl leukotriene receptor 1 modulates retinal immune cells, vascularity and proteolytic activity in aged mice.” The study, led by first author and corresponding author Andreas Koller from the University Hospital of the Paracelsus Medical University, found that blocking an inflammatory receptor … Read more
Treatment shows potential to slow the progression of human degenerative eye diseases, including retinitis pigmentosa. Researchers at the National Institutes of Health (NIH) have developed eye drops that extend vision in animal models of a group of inherited diseases that lead to progressive vision loss in humans, known as retinitis pigmentosa. The eye drops contain … Read more
Vision changes are an inevitable part of aging, but why are some more susceptible to age-related eye diseases and why do some individuals experience more severe decline than others? New research from The Jackson Laboratory (JAX) reveals that genetics play a key role in how the eye ages, with different genetic backgrounds influencing retinal aging … Read more
