Introduction to the classification of optic nerve atrophy, what are the main features of optic nerve

There are two types of optic nerve atrophy: primary and secondary.

Optic nerve atrophy is classified as primary and secondary.

Optic nerve atrophy is a blinding eye disease in which optic nerve fibers degenerate, resulting in conduction disorders.

Primary (simple) optic nerve atrophy.

There are two types: primary and secondary.

Primary and secondary.

It is divided into three types: primary optic nerve atrophy, secondary optic nerve atrophy, and ascending optic nerve atrophy. It can occur at all ages, and there is no gender difference.

Optic nerve atrophy is primary and secondary.

Optic nerve atrophy is divided into primary and secondary optic nerve atrophy.

The main manifestations are vision loss and grayish-white or pale optic discs. When the nerve fiber layer around the optic disc is damaged, a fissure or wedge-shaped defect may be revealed, and the former becomes darker, which is the exposure of the retinal pigment layer; The latter is redder and has the vularoid exposed. Lesions are easier to identify if they occur in the upper and lower margins of the optic disc because the nerve fiber layer is particularly thickened in that area, and if the lesion is far from the optic disc area, it is not easy to detect because of the thinning of nerve fiber conduction in these areas.

Focal atrophy around the optic disc often indicates a lesion in the 9,000-dimensional layer of the nerve, which is due to thinning of the nerve fiber layer in this area. Optic nerve atrophy is divided into primary and secondary: the former has a clear optic disc boundary, and the physiological depression and cribriform plate are visible; The latter is indistinct, and the physiological depression and cribriform plate are not visible.

The above is an introduction to the symptoms and manifestations of ocular nerve atrophy, and I hope it will be helpful for those who suffer from Nakuan. In the event of a similar situation, it is best to go to a regular hospital for comprehensive diagnosis and treatment, and do a good job of usual nursing measures, so as to strive for the condition to be cured as soon as possible.

Optic nerve atrophy voltan refers to the lesions of nanoretinal ganglion cells and their axons caused by any disease, generally the axonal degeneration of ganglion cells between the retina and the lateral geniculate body, causing more common optic nerve atrophy, mostly intracranial hypertension or compressive lesions leading to optic nerve atrophy, the clinical manifestations of optic nerve atrophy mainly include progressive vision loss in patients, centripetal visual field narrowing, and hail bottom examination of the eye hole hall shows that the optic disc color is light, the boundary is clear, and the cup-to-plate ratio is increased. At this time, the patient's visual acuity is mostly index or manual, and it can occur in either one eye or both eyes.

Primary optic nerve atrophy is caused by damage to the optic nerve cross-optic number behind the cribriform plate and the visual pathway of the lateral geniculate body, and its atrophy process is descending, and the primary lesions of secondary optic nerve atrophy are in the optic disc, retina, choroid, and its atrophy process is ascending. For optic nerve atrophy, there is currently no specific method, only active primary disease to delay its progression.

Analysis: Symptoms of optic nerve atrophy include vision loss and grayish-white or pale optic discs. There are a variety of factors that determine the normal optic disc tone.

Under normal circumstances, the temporal color of the optic disc is mostly lighter than that of the nasal side, and the degree of temporal color is related to the size of the physiological cup. The optic disc is often pale in infants, or it is caused by optic disc ischemia caused by compression of the eyeball during examination. Therefore, optic nerve atrophy cannot be diagnosed only based on whether the structure and color of the optic disc are normal, but it is necessary to observe whether there are changes in the retinal blood vessels and the nerve fiber layer around the optic disc, especially the visual field color vision and other examinations, and comprehensive analysis to determine the degree of pallor color of the optic disc.

Lesions in the nerve fiber layer around the optic disc may be fissured or wedge-shaped, with the former becoming darker and the retinal pigment layer exposed; The latter is redder and has the vularoid exposed.

Typical symptoms of cerebellar atrophy include loss of balance and unsteadiness on standing.
