Neuro-ophthalmology is an academically-oriented subspecialty that merges the fields of neurology and ophthalmology, often dealing with complex systemic diseases that have manifestations in the visual system. Neuro-ophthalmologists initially complete a residency in either neurology or ophthalmology, then do a fellowship in the
Visual impairment is caused by factors including brain damage, vision loss, and others. [4] Of the vision rehabilitation techniques available, most center on neurological and physical approaches. According to the American Academy of Ophthalmology, "Provision of, or referral to, vision rehabilitation is now the standard of care for all who ...
Confrontation visual field testing is an important part of a routine ophthalmological or neurological examination. It can be used for rapid and gross assessment of large-scale visual field problems due to ophthalmological or neurological diseases, such as homonymous and heteronymous hemianopias, quadranopsia, altitudinal visual loss, central/centrocecal scotoma etc. [1] [2] Test using a red ...
The term neurological visual impairment (NVI) covers both CVI and total cortical blindness. Delayed visual maturation, another form of NVI, is similar to CVI, except the child's visual difficulties resolve in a few months. Though the vision of a person with CVI may change, it rarely if ever becomes totally normal.
System: Eye and visual system: Significant diseases: Cataract, retinal disease (including diabetic retinopathy and other types of retinopathy), glaucoma, corneal disease, eyelid and orbital disorders, uveitis, strabismus and disorders of the ocular muscles, ocular neoplasms (malignancies, or cancers, and benign eye tumors), neuro-ophthalmologic disorders (including disorders of the optic nerve)
The visual cortex located in the occipital lobe of the brain is that part of the cerebral cortex which processes visual information. [26] Cortical blindness refers to any partial or complete visual deficit that is caused by damage to the visual cortex in the occipital lobe. Unilateral lesions can lead to homonymous hemianopias and scotomas.

Visual neuroscience is a branch of neuroscience that focuses on the visual system of the human body, mainly located in the brain's visual cortex. The main goal of visual neuroscience is to understand how neural activity results in visual perception , as well as behaviors dependent on vision.
