Does extreme myopia cause retinal detachment, and what are the consequences of continuous retinal de

There are four reasons why high myopia can lead to retinal detachment:

1. Because the eyeball not only becomes larger and longer-the sclera continues to expand, but the area of the retina is fixed after it matures, with the expansion of the sclera on the outer wall of the eyeball, the retina will be pulled thinner and thinner, and the thin retina is easy to tear, resulting in retinal tears, resulting in hiatal retinal detachment.

2. High myopia is closely related to heredity, and the vitreoretina around it is often abnormal, such as retinal degeneration, vitreous spots, etc.

3. Vitreous liquefaction, the gyratory force of liquefied vitreous movement and the residual vitreous traction are also one of the reasons for retinal detachment.

4. Due to the continuous thinning of the sclera, the eyeball is getting bigger and bigger, and the posterior staphyloma is becoming more and more obvious, and at the same time, due to the liquefaction and degeneration of the vitreous, the proliferative film is produced in front of the retina. The presence of these two different directional forces produces centripetal or annular traction by epiretinal membrane and vitreomacular traction, and outward expansion force is generated by staphyloma and progressive scleral extension, resulting in traction, which can produce local traction retinal detachment in the posterior pole.

High myopia refers to myopia above 6, which can lead to retinal detachment, mainly due to the fact that high myopia can have a longer eye axis, stretching the vitreous and retina, resulting in retinal detachment and vitreous liquefaction, which is manifested as a dark shadow in front of the eyes. For retinal detachment, there may be a significant decrease in vision, and it is necessary to go to the hospital in time to check the fundus to make a clear diagnosis. For those with mild detachment symptoms, laser can be used**, and retinal detachment is more severe, resulting in significant visual loss, retinal reduction surgery is also required.

Retinal detachment is a 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. 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.

Severe retinal detachment can lead to vision impairment and blindness due to the inability of the eye to work, which is a common eye disease for us. Myopia changes the eyeball, and stretching the retina can easily cause the retina to detach, which can lead to retinal dislocation over time. If retinal detachment is not undertaken, the eyeball will eventually shrink, and the success rate of simple retinal detachment surgery is more than 90%, and the success rate is relatively high.

If you are in a mild myopia group, it is recommended that you wear glasses from time to time to delay the progression of myopia.

The most serious thing is complete blindness, so after the operation, you must lie down in strict accordance with the doctor's requirements, and you can use a little auxiliary equipment when you lie down

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.
