How many types of optic nerve atrophy are there? What are the typical symptoms of optic nerve atroph

The symptoms of optic nerve atrophy are complex and complex, and the symptoms reflected in the atrophy of the optic nerve are different depending on the location, mainly including: vision changes and visual field changes.

The causes of optic nerve atrophy are varied, such as ischemia, intoxication, genetics, tumor compression, intracranial hypertension, optic nerve inflammation, trauma, etc., which are divided into primary and secondary optic nerve atrophy. The primary disease is usually a problem with the optic nerve and optic center in the posterior part of the eyeball, which is a descending atrophy. Secondary optic nerve atrophy is a primary disease of the optic disc and retina, which is ascending.

Therefore, optic nerve atrophy will be accompanied by the manifestations of ** diseases, which are systemic, such as headache, dizziness, liver and kidney and other organ damage. There are also ocular local, such as eye pain, corneal conjunctival lesions, etc. After optic nerve atrophy, the following typical manifestations will occur:

Visual field changes: visual field changes occur depending on the location and extent of optic nerve atrophy, and visual field changes may be the first symptom of optic nerve atrophy. Thinning of the nerve fiber layer around the optic disc in the fundus.

Changes in visual acuity, optic nerve atrophy leads to gradual loss of vision, and in severe cases, blindness.

The main clinical manifestations of optic nerve atrophy are decreased visual acuity and acquired color vision impairment (red-green color blindness is more common). Some patients may also have grayish-white or pale optic discs, thickening or thinning of the nerve fiber layer, etc., and generally no complications occur.

1. Typical symptoms.

1. Vision loss: Most patients have obvious vision loss, which can be accompanied by visual field defects, such as central scotoma tubular visual field and temporal hemianopia in both eyes.

2. Acquired color vision disorder: patients with optic nerve atrophy can have acquired color vision disorder, with red-green color blindness being the most common, that is, they cannot distinguish colors correctly and affect normal life.

2. Other symptoms.

Patients with optic nerve atrophy may also have grayish-white or pale optic discs, thickening or thinning of the nerve fiber layer, etc.

Symptoms of optic nerve atrophy: 1. The main thing is vision loss, and the degree of vision loss is related to the occurrence of diseases, such as acute or chronic, and also related to the degree of lesions. Second, the main reason is that there is a corresponding defect area in the visual field range, that is, the visual field innervated by the atrophic optic nerve may not be seen clearly, and visual field defects appear.

3. The loss of color discrimination ability may be due to poor vision and optic nerve atrophy, which is mainly due to the above symptoms.

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.
