|Neuro-Ophthalmology is the area in charge of visual disorders related to the nervous system. It is the bridge between Neurology and Ophthalmology, therefore it is responsible for assessing the visual symptoms caused by diseases of the optic nerve and visual pathways. It also treats disorders of the eye’s movement or function of the eyelids, related to alterations in the nervous centers responsible for their control.|
The optic nerve is a structure which includes nerve fibers from the retina responsible for processing and converting light stimuli into electrical signals. These signals travel along the optic nerve located in the back of the eyeball and continue reaching the brain, where the images are interpreted and finally we are able to understand what we see.
The neuro-ophthalmologic disorders occur when alterations/distortions of the optic nerve exist in the visual pathways (pathways that carry information from the eye to the brain), the occipital cortex (site of the brain where images are interpreted) or the oculo-motor system (system responsible for monitoring the movements of the eyes).
These conditions can be inflammatory, infectious, tumor, vascular (ischemic or deficiencies in the blood supply, hemorrhage, aneurysm) or of demyelinating autoimmune origin.
Some alterations in the function of the eyelids can also be caused by neuro-ophthalmological diseases.
