Optic neuritis symptoms?
summary
Optic neuritis or optic nerve papillitis is the general term for inflammation of any part of the optic nerve, which generally refers to inflammatory demyelination, infection, non-specific inflammation and other diseases of the optic nerve. Clinically, according to the location of the lesion, optic neuritis can be divided into intrabulbar optic neuritis and retrobulbar optic neuritis. Optic neuritis is mostly unilateral, optic papillitis is more common in children, retrobulbar optic neuritis is more common in young adults. Optic neuritis symptoms? Let's talk about it
Optic neuritis symptoms?
Non simple optic atrophy: the optic nerve papilla is mainly characterized by fuzzy boundary, grayish white or waxy yellow. Due to the proliferation of glial tissue, the physiological depression disappears, and the scleral cribriform plate hole cannot be seen. The white sheath of retinal blood vessels can be seen around the nipple or the whole fundus, which is full and tortuous or thin. Some cases also have choroidal atrophic spots and pigmentation, mainly including: ① optic atrophy secondary to optic neuritis. ② Optic nerve atrophy secondary to optic nerve papilledema. ③ Retinitis pigmentosa secondary to optic atrophy.
Simple optic atrophy: the optic nerve papilla boundary is clear, all or part of the pale, scleral cribriform plate hole membrane clearly visible. Except the optic nerve papilla, there were no other changes in the fundus, mainly including: ① optic atrophy secondary to retrobulbar neuritis. ② Demyelinating disease and leukodystrophy lead to optic atrophy. ③ Traumatic fracture of the optic canal, transection or contusion of the optic nerve. ④ Compression optic atrophy caused by intracranial inflammation is common in tuberculous meningitis, occult bacterial meningitis or optic chiasmatic arachnoid inflammation limited to the intracranial segment of optic nerve.
When optic papillitis occurs, the optic papilla is congested, slightly uplifted (less than 3D), the edge is unclear, the physiological depression disappears, the retinal vein is filled and tortuous, the retinal edema around the optic papilla is turbid, flaming hemorrhage and yellowish white exudation, and sometimes it can affect the macular region, leading to radial edema and wrinkles in the macular region. In retrobulbar neuritis, the fundus is normal in the early stage, and the color of optic papilla becomes pale and optic nerve atrophy in the late stage.
matters needing attention
In acute cases, due to the inflammation and swelling of the optic nerve fibers, if the time is too long or the inflammatory reaction is too severe, the optic nerve fibers may degenerate and necrosis. Therefore, it is very important to control the inflammatory reaction early and avoid the involvement of optic nerve fibers.
