A new video looks at vision loss and asks if lost sight can be restored. It features Juliette McGregor, an assistant professor of ophthalmology at the University of Rochester Medical Center, who explains common misunderstandings about blindness.
McGregor says it is better to think of blindness as a spectrum of visual impairment. The experience depends on which part of the eye or brain is affected, how severe the problem is, and how well a person can adapt.
In many cases treatments can reduce or prevent more vision loss. For other conditions medical options are limited and care focuses on assistive support such as devices or training. Researchers at the university continue to study the causes of vision loss.
