Will retinal detachment occur if myopia exceeds 1,000 degrees? How to prevent retinal detachment if myopia is high?

Generally speaking, 700 degrees or more is considered high myopia. People with high myopia need to protect their eyes. On the one hand, the degree cannot be deeper, and on the other hand, it may cause retinal detachment. So will high myopia definitely cause retinal detachment?

Will myopia of more than 1,000 degrees definitely lead to retinal detachment?

uncertain.

Retinal detachment is a serious complication of high myopia, and high myopia is also a high-risk factor for retinal detachment. However, not all retinal detachments are caused by myopia, and not all high myopia will lead to retinal detachment.

Retinal detachment is divided into rhegmatogenous retinal detachment and exudative retinal detachment. Rhegmatogenous retinal detachment is caused by a hole in the retina, just like a leaky airtight bag, the two layers of membrane cannot stick together, so they fall off.

For patients with high myopia, because the eyeball becomes longer, the retina is stretched and thinned. If it is too thin, it is easy to break. Therefore, patients with high myopia often suffer from this type of rhegmatogenous retinal detachment.

When there is excessive exercise, if there is a collision or excessive shaking, it may cause abnormal traction on the retina, causing holes in the already thin retina.

In this type of retinal detachment, if a hole is found, the hole can be closed surgically, and the area around the hole can be welded to the wall of the eyeball like welding to reposition the retina. The quality of postoperative recovery is related to the location of the hole, the range of detachment, and the duration of detachment. The closer the hole is to the periphery, the smaller the range of detachment, and the shorter the duration of detachment, the better the effect of the surgery will be, the more ideal the recovery will be, and even normal vision can be restored.

How to prevent retinal detachment with high myopia

1. Patients with high myopia should take better care of their eyes than others. Do not stare at computers and mobile phones for too long, and do not read for too long. You should relax your eyes in about an hour, change your field of vision and viewing distance, close your eyes to rest or look into the distance.

2. People with high myopia should avoid strenuous exercise in daily life, especially explosive exercise such as basketball and jogging, so as to avoid severe vibration of the head and reduce the risk of retinal detachment.

3. People with high myopia can supplement more vitamin A in their daily diet, such as eating carrots, pork liver and other foods, to increase the nutrition of the eyes and improve the immunity and resistance of the eyes.

4. People with high myopia should go to the hospital for regular check-ups. Timely detection and identification of the site of retinal lesions will have a positive effect on the treatment of retinal detachment. When floaters, black screens, flashes, or a sharp decrease in vision occur, you should be aware of the risk of retinal lesions and go to the hospital for examination as soon as possible.

What are the symptoms of retinal detachment?

First, there is a flashing sensation in the eyes.

This is caused by the shaking of the vitreous body in the eye and the traction of the retina. The patient can clearly feel the direction of the flash. This is usually the earliest symptom of retinal detachment and often occurs in patients with high myopia.

Second, there is a dark shadow blocking the view.

Due to severe shaking of the vitreous body, the patient's retinal blood vessels are pulled apart, and the patient will feel a black shadow floating in his field of vision, and the black shadow will continue to move toward the center of the field of vision.

Third, a large number of floaters suddenly appear.

If a patient has never had floaters before but suddenly develops them, or if the number of floaters suddenly increases rapidly, it must be taken seriously, as this may be caused by ruptured retinal blood vessels and is one of the precursors to retinal detachment.
