I am more than 600 degrees myopia, will the retina fall off?

Just because you don't know what a flash of light is, your retina won't fall off.

600 degrees won't, don't worry about it.

Problem description: Myopia has been around for several years, but fortunately it has not continued to develop, I heard that high myopia is easy to retinal detachment, is it true? What should I pay attention to to ensure the safety of my eyes, thank you!

Analysis: Retinal detachment is a very serious fundus disease. If it occurs and is not timely**, it can eventually lead to serious consequences such as blindness and eye atrophy.

The retina of the human eye is divided into a neuroepithelial layer and a pigmented epithelial layer. Retinal detachment occurs when fluid enters and accumulates between two layers of tissue, leaving the neuroepithelial layer from its original anatomical position.

High myopia is the trigger.

The most common cause of retinal detachment is high myopia. High myopia can cause retinal degeneration, which in turn causes retinal tears, which can lead to retinal detachment. In addition, vitreous degeneration, trauma, as well as eye inflammation, eye tumors, kidney disease, diabetes, gestational hypertension, etc., can also cause retinal detachment.

When retinal detachment occurs, patients often feel that small black shadows in front of their eyes are dotted or flaky and flutter with the rotation of the eyeball, and some are accompanied by flashes, water ripples, visual distortion, and even dark shadows in the visual field. Vision loss occurs in all patients, but the timing and degree of vision loss vary depending on where the retina is detached.

To prevent retinal detachment, patients with high myopia should pay attention to avoid violent head vibrations in daily life, such as bumps, bungee jumping, disco jumping, etc. If you notice dark shadows, flashes of light, or distorted vision, you should go to the hospital for examination as soon as possible. People who have a history of retinal detachment should avoid exertion, stress, temperature difference, unclean air, and even taking a plane to prevent it**.

In people with high myopia, the retina can really fall off; As the myopic eye grows, the axis of the eye gradually lengthens, and the extent of the retina is limited, so with the process of elongation, the retina becomes more and more unstable.

This is not necessarily the case. However, high myopia is very likely to cause retinal detachment. So if you find it early, then you must do it as soon as possible**.

It is possible, and in the case of greater damage, it will fall off. It's such a relationship, especially normal.

Retinal detachment caused by myopia can be solved by surgery, and the way of surgery can only be determined after examination, and generally speaking, relatively small tears can be solved by external retinal surgery. If the relatively large tear or omentum proliferation is very severe, that is, the retinal detachment has caused some subomental proliferation after a long time, then it can only be solved by internal surgery. Internal surgery is relatively complicated and expensive, so if you feel like you have a retinal detachment, you should go to the hospital as soon as possible.

Retinal detachment is a very common fundus disease in ophthalmology, and the most common cause of retinal detachment is high myopia. For this case, it is recommended that it is necessary to immediately ** once it is found, and at present, surgery is still the main treatment for the disease of retinal detachment, and external surgery, including episcleral pad pressure or scleral cerclage, which is mainly suitable for the situation where the detachment range is relatively small or the detachment time is relatively short. Internal surgery, also known as vitrectomy, is mainly used for particularly large areas of detachment, such as involving the macula or a very large retinal tear, in which case vitrectomy surgery needs to be considered**.

Retinal detachment of the eye is a very serious fundus disease, the retina should be in its own place, there is a lot of vision on the retina, and photoreceptor cells are very important for human vision. If the retina falls off due to some external force or its own factors, and departs from its original position, it is impossible to receive visual information through the retina to the center to receive visual information.

Therefore, the general patient will feel that the vision is severely reduced, and the thing to do at this time is to immediately go to the ophthalmologist to check what the retinal detachment is and how large the area of the loss is. If it is a small area of loss, you can use a laser to hit the peeling part of the fundus, like sewing clothes, sewing the fallen off position back to make it reset normally. If the area of retinal detachment is large, an intraocular surgery called vitrectomy may be done to properly reset the retinal detachment.

After the operation, you should pay attention to your usual living habits, do not get too close to observe a certain object, and do not observe an object for a long, long time.

You should go to the hospital in time for a formal examination, choose to have surgery ** or conservative** according to the doctor's advice, and adjust your work and rest routine, keep enough rest, and take correct care of your eyes.

Need to go to the hospital to receive**, this condition can easily be dangerous, can also lead to infection, be sure to go to the hospital.

Because of high myopia, his eye axis has been elongated, and the elongation of the eye axis will cause the retina and choroid to form a strong tension, which will cause the retina and the vitreous connection point to rupture and perforate, so eventually form a macular hole, macular split, and retinal detachment. The retina of the human eye is very thin, only 100 200 microns. It's like one, it's easy to break.

Under the physical impact, it is easy to fall off. Where the photochemical reaction of the retina is strongest, various oxidative stresses form oxidative damage substances here, forming inflammation and destruction of the fundus. High myopia, with all of the above conditions, causes the retina to detach very easily.

High myopia is not only the inability to see clearly, but also the possibility of a change in the shape of the eyeball, i.e. an increase in the anterior and posterior diameters. As the shape of the eye changes, the retina and choroid at the back of the eye are stretched, resulting in deformation of the retinal choroid; If a tear develops, there is a risk of retinal detachment, which can lead to blindness.

In general, for every 300 degrees increase in myopia, the anterior and posterior diameter of the eye increases by about 1 mm. Therefore, the higher the degree of myopia, the greater the risk of retinal detachment. According to statistics, about 70% of patients with retinal detachment are myopia, of which 30% and 40% are high myopia.

For retinal detachment to occur, two conditions must be present: the presence of a retinal tear and vitreous liquefaction. Retinal detachment occurs only when these two conditions are present.

If a patient has a retinal tear and the vitreous is jelly-like, and no liquid flows through the tear to the retina, a retinal detachment will not form, and the tear is called a dry retinal foramen. Physician Advice: Recommendation:

Due to the gradual lengthening of the eye axis of the highly myopic eye, the vitreous humor is easy to liquefy and degenerate, the retina of the fundus will be stretched longer and longer, the peripheral retina lacks blood oxygen and effective**, and the thin retina is prone to atrophic tears. Especially during strenuous exercise, the movement of the liquefied vitreous body pulls the fragile retina, causing a hole in the retina, and the liquefied vitreous will penetrate through the hole, resulting in retinal detachment.

Moderately high myopia, it is better not to do strenuous exercise.

Myopia refers to the fact that parallel light rays enter the eyeball, are refracted by the refractive system of the eyeball, and cannot converge on the retina, but converge before the retina, which is called myopia.

The clinical manifestations of myopia are mainly that the vision is not clear from afar, and the vision is clear from near and near. Myopia can be divided into low myopia below 300 degrees, moderate myopia between 300 degrees and 600 degrees, and high myopia above 600 degrees.

In people with moderate myopia and high myopia, the retina is less fragile due to degeneration. However, if people with moderate to high myopia are engaged in bungee jumping activities, retinal tears and retinal detachment may occur due to the large relative force generated by bungee jumping.

Therefore, people with moderate myopia and high myopia should not do bungee jumping, while people with low myopia and normal non-myopia can take bungee jumping. Strenuous exercise is not recommended with or without surgery.
