There are often misconceptions around the idea of blindness. According to Juliette McGregor, an assistant professor of ophthalmology at @URochesterMedicine it’s better to think of a spectrum of visual impairment, ranging from minor problems to no light perception.
The type of vision loss a person has—and the impact that loss has on their daily life—depends on which structure of the eye or the brain is affected, the severity of the problem, and the patient’s ability to adapt.
In many cases, there are treatments available to minimize vision loss. But for others, there is little that medicine can currently offer beyond assistive support. Several labs at the University focus on understanding the causes of vision loss, including those at the @flaumeyeinstitute and the @URNeuroscience. However, the breakdown of retinal neurons is still mysterious in many ways.
Watch as McGregor explains the latest research and new treatments that could be on the horizon.
