How can optic nerve damage be detected early?

Glaucoma patients or suspected glaucoma patients are advised to visit a professional eye hospital every year to have a clear optic nerve photograph**.

Fundus photography can quickly obtain color images of the fundus in different visual fields such as retina, optic nerve, macular or choroid, which is intuitive and accurate, and has a digital preservation function, which is convenient for doctors to read optic nerve photography at different stages, and once suspicious signs are found, glaucoma can be further examined and detected early.

In addition, there are intraocular pressure tests, visual field tests, ophthalmoscopy, and so on. Experienced glaucoma doctors can also use a special ophthalmoscope to observe changes in the optic nerve in the eyeball, whether there is compression and atrophy, or bleeding.

1. To diagnose glaucoma, is it necessary to find optic nerve damage?

In some cases, no evidence of optic nerve damage is required to diagnose glaucoma, such as secondary glaucoma, primary angle-closure glaucoma, congenital glaucoma, etc. For primary open-angle glaucoma, we generally need evidence that optic nerve damage has already occurred, or evidence of an imminent high-risk risk of optic nerve damage, to confirm the diagnosis of glaucoma. This is because for some patients with elevated intraocular pressure or atypical glaucomatous optic nerve visual field changes without optic nerve damage, we generally observe the progression of the disease as a suspected case.

After all, the diagnosis of primary open-angle glaucoma is a lifelong disease. So I'll be more cautious. For suspected cases, whether to give ** should be comprehensively evaluated according to the patient's age, general condition, and risk of optic nerve damage.

For patients with limited life expectancy, in order to improve the patient's quality of life, drugs may not necessarily be given**, and observation alone may be sufficient. Mao Jin, Department of Ophthalmology, Beijing Aier Yingzhi Eye Hospital.

2. What is the most effective way to detect optic nerve damage in early stage?

At present, there are many ways to detect optic nerve damage, including fundus color photo, OCT, GDX, HRT, visual field, etc. However, the most effective means of detecting early damage include fundus optic disc stereography (particularly time series series**); Analysis of the thickness of the optic disc nerve fibers of OCT and measurement of the thickness of the macular ganglion cell complex; This is followed by the analysis of the visual field, GDX nerve fiber thickness. Certain electrophysiologic tests, such as IC-VEP, that measure specific cell function in the macula, may also be of some value for early detection of optic ganglion cell damage.

3. What problems can be found in fundus stereoscopic photography? Will the results of the shoots at different hospitals affect the diagnosis? Will different doctors' interpretations come to different conclusions?

Fundus stereotype** is the stereoscopic shape of the fundus optic disc that is taken, and it is generally taken in two pictures at the same time, which requires special equipment or lenses to read the results. Its value lies in the discovery of subtle structural changes along the optic disc edge. If the fundus disc photography meets the standard stereoscopic **, the results should be basically the same from hospital to hospital and will not affect the diagnosis.

However, different doctors, because of their experience and different criteria for judging damage, will make different judgments about the same photographic results. This kind of person-to-person bias cannot be completely avoided.

4. Is MRI helpful in the diagnosis of glaucoma?

Helpful, particularly in some patients with low intraocular pressure and possible cerebrospinal fluid dysfunction, and is useful in excluding optic nerve damage due to mass lesions such as the head and pituitary gland. However, magnetic resonance imaging of the optic nerve itself is of little value in diagnosing optic nerve damage.

At present, there are many methods to detect optic nerve damage, including fundus color photography, OCT, GDX, HRT, visual field, etc. However, the most effective methods for detecting early injury include stereoscopic imaging of the optic disc in the fundus (especially time series**); Optical coherence tomography analysis of optic nerve fiber thickness and measurement of macular ganglion cell complex: the second is the analysis of visual field and GDX nerve fiber thickness.

Some electrophysiological tests that measure specific cell function in the macula, such as visual evoked potentials, are also valuable for early detection of optic ganglion cell damage.

If you want to detect optic nerve damage at an early stage, you need to go to the hospital for regular eye checkups.

And during the examination, you must do a comprehensive and detailed examination, and pay attention to your eye hygiene and hygiene.

How to detect early is nerve damage, if you find something wrong in the body early, you can find it by seeking medical attention in time.

Early detection, early ** may be better.

It is recommended that you must go to a regular hospital to do a professional, brain surgery to check the attack of the brain, or an MRI, so as to make a clear judgment, according to the severity of the injury and the clinical manifestations, so as to make a correct and clear judgment. aqui te amo。

At present, there are many ways to detect nerve damage, including human color ultrasound, OCT GD X HR7 field of view, etc., but the most effective means to detect early damage, including fundus optic disc stereoscopic photography, is recommended to be examined by doctors.

When you look at things, you will have phantoms, your eyes will not be able to see things with light, your eyes will be very painful, the muscles around your eyes will be particularly numb, and your vision will be reduced and you can't see things. The optic nerve determines the eyeball, and if there is a lesion, the eye will feel it clearly.

There is a possibility of insomnia, which can lead to vision loss, which may cause the retina to become more and more blurry, which may cause redness, swelling or pain in the eyes, and then redness may appear, which can lead to retinal detachment.
