In ophthalmology clinics, 10-15% of patients are neuro-ophthalmologic, in neurosurgery, 35% are neuro-ophthalmologic problems, and in neurology, 36% of diseases are related to neuro-ophthalmology. All kinds of primary or secondary neurological pathologies that manifest clinically with ocular symptoms or signs fall under the category of neuro-ophthalmology. Neuro-ophthalmologic diseases include the following major categories: 1, visual afferent system diseases [optic nerve diseases (optic neuritis, various optic neuropathies, optic papillopathy, hereditary optic neuropathy, optic nerve tumors, congenital optic disc dysplasia, traumatic optic neuropathy, etc.; optic cross (optic pathway) lesions; anterior circulation, posterior circulation diseases related to neuro-ophthalmology; intracranial venous sinus thrombosis related to neuro-ophthalmologic diseases]. 2. Diseases of the efferent system (supranuclear, internuclear, nuclear, and subnuclear ophthalmoplegia, oculocutaneous nerve, talipes, adductor nerve, etc.); 3. Pupillary abnormalities: Adie’s pupil, Argrll Robertson’s pupil, Horner’s syndrome, dilated pupil, etc.; 4. Nystagmus; 5. Eyelid and other diseases; 6. Systemic diseases related to Neuro-ophthalmology. Optic nerve diseases include: optic neuritis, Leber’s stellate nerve retinitis, nodular optic neuropathy, syphilitic optic neuropathy, anterior ischemic optic neuropathy (arteritis, non-arteritis), hypertensive optic neuropathy, diabetic optic papillopathy, radiation optic neuropathy, pharmacologic, nutritional and toxic optic neuropathy, optic papilledema, optic nerve-related tumors optic nerve atrophy, Leber hereditary optic neuropathy, congenital optic disc anomaly, optic disc vitreous warts, optic nerve dysplasia, optic disc defect, optic disc microsaccades, traumatic optic neuropathy, etc. Optic cross-related diseases include: 1, various intracranial occupying diseases: pituitary tumors; craniopharyngioma; meningioma; aneurysm; dermatomes and metastatic lesions; 2, various intracranial inflammatory diseases and other intracranial diseases: inflammatory diseases (lymph pituitary inflammation, etc.), demyelinating diseases, nodal diseases, etc.; 3, diseases of the optic pathway above the optic cross: optic bundle, lateral geniculate gland, optic radiation disease type I optic bundle syndrome (occupying); 4, type II Optic bundle syndrome (demyelination or infarction): temporal, parietal, occipital lobe lesions cortical blindness. Diseases of the efferent system: III cranial nerve palsy, IV cranial nerve palsy, VI cranial nerve palsy, V cranial nerve disease, multicranial nerve palsy, internuclear ophthalmoplegia, gaze palsy, chronic progressive ophthalmoplegia, progressive supranuclear ophthalmoplegia, GBS syndrome, myasthenia gravis, dorsal midbrain syndrome.
