Neuro-ophthalmology is a specialized field of medicine that focuses on diagnosing and treating eye conditions related to the nervous system, particularly the brain and optic nerve. This includes problems with vision that are caused by neurological disorders, such as optic nerve damage, visual disturbances due to brain injury or disease, and conditions like double vision or involuntary eye movements. Essentially, neuro-ophthalmologists help patients with eye problems that have roots in the brain or nervous system.
