Neuro-ophthalmology is a specialized field of medicine that focuses on the relationship between the nervous system and the eyes. It involves diagnosing and treating visual problems that are caused by neurological conditions, such as multiple sclerosis, stroke, or brain tumors. This branch of medicine combines aspects of both neurology and ophthalmology, allowing doctors to understand how issues in the brain and nervous system can affect vision. Common conditions treated include optic neuritis, double vision, and visual field loss. Neuro-ophthalmologists use various tests to assess eye function and diagnose underlying neurological disorders.
