The most common retinal detachment is rhegmatogenous retinal detachment, which mainly occurs in high myopia.
In the case of high myopia, the retina can degenerate and become thinner, and then its vitreous body.
Will have abnormal adhesion with the retina. Under the traction of vitreous body, retina can split. After there is a hole in the retina, the intraocular fluid enters the retina and the retina can be detached. This is the most common reason. Other retinal detachment can be caused by other reasons, such as eye trauma. After the patient is injured, it can directly lead to retinal rupture and detachment. In addition, other diseases, such as fundus hemorrhage caused by hypertension and diabetes, as well as some vascular diseases of fundus, will cause retinal detachment.
It is generally believed that people aged 40-60 are prone to retinal detachment. However, there are more and more people suffering from myopia, especially more and more patients with high myopia, which makes it possible for teenagers to suffer from this disease. Because it is almost impossible to reset naturally after retinal detachment, it is necessary to treat the symptoms in time.
Doctor: Generally speaking, the earliest (symptom) is the feeling of Fei Ying in front of us, which can also be called the shadow in front of us. This is a common early symptom of retinal detachment. But not all patients have this (symptom), that is, retinal detachment, but for patients with this symptom, especially his own high myopia or eye trauma, these are common risk factors for retinal detachment. In this case, he should go to the hospital for examination as soon as possible.
Here, patients should be reminded not to rub their eyes or engage in strenuous activities if there are symptoms such as flying spots or flashing lights in front of them. In addition, we should also be careful not to drop eye drops casually, especially when our eyesight drops, and go to the hospital as soon as possible to find out the reason.
The following people are prone to retinal detachment.
1。 Myopia, especially patients with moderate or high myopia.
2。 One eye has had retinal detachment, and the other eye is more prone to retinal detachment.
3。 Combined with other eye diseases: such as eye trauma, repeated vitreous hemorrhage, etc.
4。 A patient who has undergone cataract surgery.
When patients have symptoms, they may have fear of eye examination, fearing that it will do harm to their eyes. Actually, it's not. When doing the examination, first enlarge the pupil and let the eyes get a full rest. After the pupil is dilated, the light of the inspection instrument can reach the back of the eyeball, so as to inspect the whole retina.
Doctor: Then after mydriasis, the doctor will examine the fundus and examine the retina with special instruments. The name of this instrument is binocular indirect ophthalmoscope, which is a lamp worn on the head. Then the doctor holds a lens in one hand, and the light emitted by the lamp shines on one side of the patient's eye through the lens, so that the doctor can observe the overall situation of the retina under the light irradiation.
Because this kind of examination does not directly contact the eyeball, it is very safe for the patient.
Experts believe that the therapeutic effect of retinal detachment mainly depends on two aspects. The most important aspect is the timing of treatment. If the disease is delayed for too long, the retinal tissue structure can not be recovered after being destroyed. Another aspect is to look at the treatment, that is to say, corresponding measures should be taken for specific symptoms.
Some mild cases usually include retinal tears that have just broken, or tears that are about to form, or very limited retinal detachment. At this time, laser can be used to treat the retina around the closed hole, so that the retina and the wall of his eye can be firmly adhered again, which can prevent the occurrence of retinal detachment.
Laser therapy is a popular treatment method at present. Its advantages are good directionality, easy energy control and no sequelae after operation. So what kind of treatment should be taken for some patients with large retinal holes but not yet detached?
Doctor: This operation is performed on the surface of the eyeball. Through condensation, the retina and the eyeball wall will have a coagulation reaction, and then the eyeball wall will be in closer contact with the retina through external voltage, thus achieving the purpose of resetting the retina.
Generally speaking, more than 90% of patients can be solved by this relatively simple eye surgery if they seek medical attention in time. If the condition drags on for a long time, some mottled proliferative reactions of the eyes need to be solved by some complicated operations of the eyes.
After the operation, in order to promote its long-term healing, the doctor will also put gas or silicone oil into the eyes at the end of the operation. The effect of this gas and silicone oil is that the specific gravity is relatively light. It can compress the retina for a long time in the eye, but this patient has a position requirement after operation, that is, he must keep prone position, so that the gas lighter than water and silicone oil can produce the effect of upward compression and promote the long-term reset of the retina.
According to the doctor, for patients with high myopia, the degree of postoperative vision recovery depends on the degree of retinal damage. If the retina falls off for more than 7 days, even if the retina is reset after surgery, it is difficult for the vision to return to the preoperative state.
Doctor: If retinal detachment lasts for more than seven days, even if it is reset by surgery, the function of photoreceptor cells in his retina will be irreversibly restored because of retinal detachment for seven days. Then his recovery of visual function after operation is limited, so his vision can't be restored to the level that he didn't get sick before operation.
At present, there are more than 5,000 students in Taiwan Province Province studying in the mainland. Many of them like surfing the Internet or playing games after finishing their studies, playing all night and not paying attention to protecting their eyes, which will easily lead to eye fatigue and poor eyesight. Once retinal detachment occurs, it will be more difficult to recover and bring great inconvenience to patients. Therefore, prevention is very important.
Preventive measures:
1。 The eyes are not easily overtired.
2。 Don't lift heavy things.
3。 Don't do strenuous exercise.
4。 Prevent the occurrence of myopia.
5。 Patients with myopia should go to the hospital regularly for examination, especially those with poor fundus.
6。 Prevent eye trauma.
7。 It is best to have a regular eye health examination every six months.
In recent years, due to the continuous improvement and perfection of surgical methods and equipment, the success rate of retinal detachment surgery has also been continuously improved, and the cure rate can reach 80%-90%. After timely surgical treatment, most patients can get rid of blindness. Therefore, both doctors and patients should establish confidence, strive for early treatment and strive for the best results.
