The optic nerve is responsible for transmitting visual information from the retina to the brain, where it is processed into the images we see. Damage or issues with the optic nerve can lead to visual impairment or even blindness if left untreated. Neuro- ophthalmology is a sub-specialty of ophthalmology that deals with the diagnosis and management of optic nerve disorders and related visual problems. Neuro- ophthalmologists are trained to identify and treat conditions affecting the optic nerve, which may include optic neuritis, optic neuropathy, and other neurological or vascular disorders that can affect vision. Early diagnosis and treatment from the Best eye hospital in Patna & Arrah by a neuro-ophthalmologist can often help prevent irreversible vision loss.
