The cause of optic disc edema

Because the reasons for his disk edema, a total of mechanism is sometimes different, hypertensive encephalopathy can not increased intracranial pressure, but partially due to ischemic optic disc, renin - angiotensin - aldosterone, and so played a major role. As the front of the ischemic disease due to interference as the optic disc blood supply, the pace of axoplasmic flow was caused by blocking. First, increased intracranial pressure * 1. Intracranial lesions (brain tumor, subdural and epidural hematoma, etc.) * 2. Fake brain tumor ⑴ leave primary brain tumor ⑵ secondary (severe head injury, * subarachnoid hemorrhage) 3. Inflammation * ⑴ meningitis, encephalitis, brain abscess ⑵ Green - Barre syndrome 4. Uremia 5. Skull stenosis * 6. Cerebral arteriovenous malformations 7. Severe chronic obstructive pulmonary disease, with higher CO2 8. Allergic serious brain lesions, such as bee stings 9. Cerebrospinal fluid of the spinal cord with increased tumor Second, the normal pressure 1. Congenital anomalies DVD 2.Leber optic neuropathy 3. Inflammation optic neuropathy ⑴ optic disc Yan ⑵ around the optic nerve inflammation * 4. Ischemic optic neuropathy 5. Toxic optic neuropathy, such as lead poisoning, methanol poisoning, etc. 6. Orbital oppression optic neuropathy (such as thyroid optic neuropathy) 7. Infiltration of optic neuropathy ⑴ leukemia ⑵ lymphoma ⑶ multiple myeloma ⑷ type of hyperlipidemia 8. Partial vascular neuropathy ⑴ malignant hypertension ⑵ central retinal vein occlusion ⑶ venous stasis of the retina diseases (ischemic) ⑷ optic disc vasculitis ⑸ young diabetic optic neuropathy ⑹ hypotony ⑺ vitreous traction ⑻ uveitis 9. Mucopolysaccharide disease
