What is optic nerve atrophy? Do you really know?

Optic nerve atrophy is a common ophthalmic disease and is a type of fundus disease. It is usually due to underlying diseases such as advanced glaucoma, optic neuritis, ischemic optic neuropathy, diabetic retinopathy, retinal artery embolism, retinal vein embolism, etc., resulting in severe structural and functional damage to the optic nerve and eventually atrophy. The main manifestations are decreased vision, visual field defects, night blindness, etc.

When the doctor examines the ophthalmoscope, he can see that the optic disc is pale in color, the cup-to-disc ratio is enlarged, and the depression formed by the optic nerve is deepened. ** The main focus is to remove the primary disease to stop and delay the further progression of optic nerve atrophy.

Optic nerve atrophy must be diagnosed by a professional ophthalmologist before it can be diagnosed, simply put, the optic disc in the eye has a pale color or pale change, called optic nerve atrophy, optic nerve atrophy refers to the degeneration of the optic nerve itself, which can be divided into primary optic nerve atrophy and secondary optic nerve atrophy. Primary optic nerve atrophy is caused by intracranial pressure, increased intraorbital pressure, inflammation or tumor compression of the optic nerve leading to atrophy, tobacco and alcohol poisoning, trauma, syphilis infection, genetics and other factors can cause optic nerve atrophy. Secondary optic nerve atrophy may be caused by inflammation of the optic nerve itself, chorioretinitis, retinal vascular obstruction, and secondary atrophy of the optic nerve due to drug poisoning, diabetes, arteriosclerosis, glaucoma, and other diseases.

Optic nerve atrophy is a diagnostic term in ophthalmology, optic nerve atrophy actually refers to the atrophy of the nerve tissue at the optic disc part of the fundus, in fact, only the beginning of the fundus is called the optic disc, and the ophthalmologist can only diagnose optic nerve atrophy when the ophthalmologist can see the atrophy with the naked eye.

Optic nerve atrophy is pathological and physiological, the latter mainly refers to the functional degeneration of the optic nerve in the elderly, and the former refers to other diseases of the body, such as intracranial tumors or traumatic bleeding, optic nerve atrophy caused by hematoma compression, and the severity of optic nerve atrophy can be improved through the primary disease.

Optic nerve atrophy refers to a variety of diseases that cause degeneration of optic nerve fibers and lead to visual dysfunction, which is a common disease, and the main cause is the lesion of the optic nerve itself and its surrounding related tissue structures, intracranial lesions, traumatic lesions, metabolic diseases, nutritional factors, genetic factors, etc., and the clinical manifestations are vision loss.

Optic nerve atrophy refers to the degeneration and conduction dysfunction of the optic nerve fibers, ganglion cells and their axons before the lateral geniculate body under various influences. In general, optic nerve atrophy is caused by a variety of causes, such as inflammation, metamorphosis, ischemia, compression, trauma, poisoning, demyelination, and hereditary diseases.

Optic nerve atrophy can be divided into three types: primary optic nerve atrophy, secondary optic nerve atrophy, and ascending optic nerve atrophy according to the manifestations of the eye and the location of optic nerve damage.

Generally speaking, if a patient has optic nerve atrophy, the first thing to do is to target it. If the optic nerve has atrophied significantly, it is not easy or impossible to heal it, but it is possible to keep the residual nerve fibers from deteriorating further.
