Researchers at Karolinska Institutet and St Erik Eye Hospital in Sweden have discovered a way to refine the production of retinal cells from embryonic stem cells for treating blindness in the elderly.

The studies are published in the scientific journals Nature Communications and Stem Cell Reports.
The American Academy of Ophthalmology this week issued a warning to its members that conjunctivitis, also known as pink eye, can be an early sign of the coronavirus in some patients.
