Early symptoms of optic atrophy?

summary

Optic atrophy is not a single disease. It is the final result of various optic neuropathy and the damage of myelin sheath or retinal ganglion cells and axons, resulting in the loss of nerve fibers and glial hyperplasia. It is a common term in pathology. Axonal degeneration of ganglion cells usually occurs between retina and lateral geniculate body. Due to the degeneration and atrophy of nerve fibers, the visual function of the patients decreased and the visual field decreased. Early symptoms of optic atrophy? Let's talk about it

Early symptoms of optic atrophy?

Primary optic atrophy is caused by the orbital, intraductal and intracranial optic nerves behind the cribriform plate, as well as optic chiasm, optic tract and lateral geniculate body damage, so it is also known as descending optic atrophy

The fundus changes of degenerative optic atrophy were limited to the optic disc, which showed that the color of the optic disc was gray and the boundary was very neat. Due to the atrophy of optic nerve fibers and the loss of myelin sheath, the physiological depression was slightly larger, slightly deeper, and appeared as a shallow dish, with gray blue dot like cribriform plate. The retina and retinal vessels were normal.

Secondary optic atrophy is caused by long-term optic disc edema or severe optic disc inflammation. Most of the lesions are limited to the optic disc and its adjacent area, so the fundus changes are limited to the optic disc and its adjacent retina. The optic disc was white due to the proliferation of neuroglia. The boundary of optic disc was unclear. The physiological depression was filled with neuroglia, so the physiological depression disappeared and the cribriform plate could not be found. The retinal artery near the optic disc may be thin or accompanied by white sheath, and the retinal vein may be slightly thick and curved. There may be some unabsorbed hemorrhage and hard exudation in the posterior retina.

matters needing attention

1. After getting up early every day, you'd better face the west before the sun comes out (don't force this point), with your feet together, your hands naturally drooping, your tongue naturally touching the gums, and stand still; 2. Close your eyes slightly, first breathe out, then inhale, then breathe out and then inhale, a total of two, and then live breathing, and then rotate your eyes to the left, that is, first left up, left down, right down, right up. Stop after 7 turns. Turn your eyes 7 times to the right;
