Early symptoms of optic atrophy?
summary
Optic atrophy refers to any disease caused by retinal ganglion cells and their axons pathological changes, resulting in all the optic nerve thinning of a morphological change, generally occurs in the retina to the lateral geniculate body between ganglion cells axonal degeneration. Early symptoms of optic atrophy? Next, I'd like to share my views with you.
Early symptoms of optic atrophy?
First, the main performance of vision loss and disc is gray or pale. When the nerve fiber layer around the optic disc is damaged, there may be crevicular or wedge-shaped defects. The former becomes black, which means the retinal pigment layer is exposed; The latter is red, which is choroidal exposure.
Second, if the lesion occurs in the upper and lower marginal areas of the optic disc, it is easier to identify, because the nerve fiber layer in this area is particularly thickened. If the lesion is far away from the optic disc area, it is not easy to find because the nerve fibers in these areas become thinner. Focal atrophy around the optic disc often indicates the lesion of nerve fiber layer, which is caused by the thinning of nerve fiber layer in this area.
Third: Although the common use of fundus examination can be found, but with no red light ophthalmoscope and fundus photography is easier to check. There are usually 9-10 small vessels in the optic disc. If the optic nerve atrophies, the number of these small vessels will decrease. At the same time, thinning, stenosis and occlusion of retinal artery were also seen.
matters needing attention
1、 Always keep a good posture. Maintain the most appropriate posture, let one eye head up or slightly gaze down on the screen, so that the neck muscles can be relaxed, and the area of the eye exposed to the air can be minimized. 2、 If you find eye discomfort, you should actively seek medical advice. Usually special attention should be paid not to direct the eyes, in addition, in order to avoid eye injury.
