New eye drops could prevent vision loss after retinal vein occlusion, a major cause of blindness for millions of adults, a study by Columbia University researchers has found.

Hundreds of patients have been diagnosed and many new genetic causes of disease discovered in a UK National Health Service programme pioneering the use of whole genome sequencing. The study, led by researchers at the National Institute for Health Research BioResource together with Genomics England, demonstrates that standardized sequencing whole genomes of large numbers of people can improve the diagnosis and treatment of patients with rare diseases.

After a brain injury, cells that normally nourish nerves may actually kill them instead, a new study in rodents finds. This 'reactive' phenomenon may be the driving factor behind neurodegenerative diseases like glaucoma, a leading cause of blindness.

A case of pink eye is now reason to be tested for COVID-19, according to University of Alberta researchers. Coughing, fever and difficulty breathing are common symptoms of the illness, but a recent case study involving an Edmonton woman and published in the Canadian Journal of Ophthalmology has determined that conjunctivitis and keratoconjunctivitis can also be primary symptoms.

How common asthma was among children with various developmental disabilities (including attention-deficit/hyperactivity disorder, autism spectrum disorder and vision, hearing or speech delay) was compared to children without disabilities in this survey study.
