Newly discovered chemical reaction in eye may improve vision

A light-sensing pigment found in everything from bacteria to vertebrates can be biochemically manipulated to reset itself, an important therapeutic advantage, according to new research out of Case Western Reserve University ...


New insight into eye diseases

Many diseases that lead to blindness, such as glaucoma and macular degeneration, are caused by the death of certain cells in the human retina that lack the ability to regenerate. But in species such as zebrafish these cells, ...


Visual pigment rhodopsin forms two-molecule complexes in vivo

The study of rhodopsin—the molecule that allows the eye to detect dim light—has a long and well-recognized history of more than 100 years. Nevertheless, there is still controversy about the structure in which the molecule ...


Potential new approaches to treating eye diseases

Potential new approaches to treating eye diseases such as age-related macular degeneration (AMD) are described in a new study, "IL-33 amplifies an innate immune response in the degenerating retina," in the February Journal ...
