Combating drug resistance in age-related macular degeneration

July 16, 2020

Researchers have discovered a strategy that can potentially address a major challenge to the current treatment for choroidal neovascularization (CNV), an aggressive form of age-related macular degeneration.

Vision loss in children whose eyesight may be 20/20 requires new diagnostic and teaching strategies

July 14, 2020

Cerebral (cortical) visual impairment (CVI) is a condition that interferes with the ability of the brain to process information from the eyes, and it has become a leading cause of visual impairment in the U.S.
