1 what is strabismus?
When the eye gaze target, the other eye axis deviates from the fixation target called strabismus. Sometimes parents will find their baby with both eyes oblique staring objects, it is not strabismus, commonly known as side, belongs to bad habits or ametropia caused by. Whether it is found or the side of strabismus should be timely to the hospital.
2 why is there a squint?
In general, non common strabismus can often check out the cause of the disease, and the common cause of strabismus is not clear. We usually say that the vast majority of strabismus is common strabismus. There are many reasons for the formation of concomitant strabismus, and even the same patient may be the result of several factors. The most common causes of concomitant strabismus are as follows:
The patients with hyperopia refractive errors: engaged in close work and early presbyopia patients, because of the need to strengthen the regulation, will produce excessive influx, resulting in esotropia. Myopia patients, because it does not need or rarely needs to be adjusted, will produce convergence insufficiency, may lead to external oblique.
The sensory disturbance: for some reason, congenital and acquired, such as corneal opacity, congenital cataract, vitreous body opacification, macular abnormalities, anisometropia is too large, resulting in retinal imaging is not clear, poor visual function, the eyes can not be established in order to maintain the balance of fusion reflex eye position, resulting in strabismus.
Genetic factors: because of the same family, the anatomical and physiological characteristics of the eye have similar characteristics, because of the abnormal anatomy of the strabismus may be passed on to the offspring in a polygenic inheritance.
3 strabismus will produce those adverse consequences?
The most important adverse effect of strabismus is the normal binocular function, which leads to the lack of stereoscopic vision. To hinder the selection of certain occupations. Children with a lack of normal visual function are not competent for such tasks as aerospace, aviation, surveying, mapping, driving, drawing, medical care, etc..
The influence of the appearance of strabismus, especially in childhood due to strabismus was ridiculed by classmates around, to hit the body and mind. Resulting in loneliness, lack of self-confidence, thus affecting the child's life. Adult strabismus seriously influences the choice of social activities and occupations.
4 when is the best time to treat strabismus?
Generally speaking, for strabismus children if not treated in time, wait until after the age of 12 may lose the binocular vision function, even after this age through surgery to solve strabismus, can play a cosmetic effect. Therefore, strabismus should be treated in time. However, for the examination, there is a slight squint children, depending on the function of the operation time. For non concomitant strabismus surgery timing, generally in the incidence of six months after surgery.
5 surgical timing of several common strabismus
Early surgery for congenital strabismus. The formation of binocular vision in children before the age of 5, is in the developmental stages of children suffering from vision such as strabismus, two eyes can not see the same object at the same time, it is impossible to binocular vision development, if not promptly corrected, eventually the child binocular vision cannot get normal development and the formation of amblyopia.
The first is caused by the ametropia strabismus correction of ametropia, and according to whether to consider the treatment of strabismus amblyopia. Generally speaking, the correction of amblyopia is priority, and after the correction of amblyopia, the operation is performed to treat strabismus.
For intermittent exotropia, if the degree of strabismus is low, usually can not see the strabismus, you can check the binocular vision based on the observation of the eye position. To promote the timely treatment of intermittent exotropia with frequent seizures.
The children for esotropia, if the skew angle is small, and is not easy to be found, and decided to change can observe the development of eye position as the disease. Generally speaking, children's esotropia can be reduced with the growth of age.
6 strabismus should be how to treat?
Strabismus most of this disease is to rely on surgery, and some are wearing glasses correction. There are even some strabismus to wear glasses and surgery. That kind of blind strabismus could be eliminated with the increase of age view is absolutely intolerable. Only those with mild strabismus were treated surgically by close observation of changes in visual function. Once found strabismus should immediately go to the hospital to see eye specialist, first understand the general plan of treatment, so as not to delay the best treatment time.
7 strabismus operation can cause eyesight to drop?
Can't， Strabismus surgery is an external eye surgery, do not enter into the eye, so it will not affect the patient's vision. Even after surgery, the transient visual acuity decreased, which was due to the visual interference and conjunctival suture stimulation.
8 why do strabismus sometimes need to be treated differently?
Generally speaking, for more than 90 of the prism strabismus patients, due to the skew angle is large, often for a plurality of extraocular muscle surgery. In principle does not allow the operation of 3 rectus muscles in one eye, otherwise it will cause the front of the eye ischemia. If you encounter such a large angle, combined with different types of strabismus, it should be clear to the patient, depending on the specific circumstances can be divided into surgery. In addition, the operation, the patient's individual differences and other factors can also affect the results of surgery. Therefore, preoperative patients and their families should be informed of the possibility of reoperation. In particular, children with congenital esotropia surgery, as a result of young children do not cooperate with the examination, the degree of strabismus surgery for the determination of the difficulties, may need to sub surgery.
9 when wearing glasses without strabismus and pick glasses after strabismus children need surgery?
Total refractive accommodative esotropia. The best treatment for this type of strabismus is wearing glasses. The utility model not only has a positive eye position, but also can be used for binocular single vision. However, some patients or families do not accept wearing a mirror, instead of surgery. This kind of operation can not change the state of refraction regulation, and there will also be esotropia. In addition, the patient does not wear a poor vision, also can not reach the purpose of the mirror. Therefore, such patients should not be treated surgically.
Partial accommodative esotropia, surgical design only to solve the non regulatory part, while the adjustment part still need to wear a mirror to solve. Should be sure to explain to patients and their families before surgery, that is, when wearing glasses when the eye is positive, there will be a certain degree of strabismus when picking glasses. After surgery should be re optometry, adjust the degree of glasses. Regular review, according to the degree of refraction and strabismus changes in time to replace glasses.
10 darling neck is crooked, why should do eye strabismus operation?
Most of the symptoms of torticollis is caused by abnormal cervical muscle. Abnormal changes in the muscles, often in the early stages of treatment can be treated by physical therapy, some patients have to be treated by surgery. However, there are also caused by abnormal child Minow eye, the neck muscles found no obvious abnormalities and Minow children should consider ocular torticollis. Due to congenital ocular muscle paralysis is the most ocular torticollis. The most common is the unilateral or bilateral superior oblique palsy. The children take this position can reduce the head tilt, strabismus discomfort. However, long-term Minow will bring many negative consequences for children. First of all, is due to head (torticollis) facial asymmetry caused by the gravity of the one side of the face is full, the other side of the face thin. Second, the impact on the neck of the bones, causing cervical scoliosis. Third, it may also cause the development of mandibular deformity. Therefore, congenital ophthalmoplegia caused by torticollis should be early surgical treatment.
11 why is it so important?
After strabismus surgery, there are a few patients with diplopia, most patients with diplopia can disappear by itself in a short period of time, the fastest one to disappear within a few weeks after operation. The children of the binocular visual function changes quickly, overcome diplopia faster than adults. For adults with strabismus, a detailed explanation of postoperative ghosting. The correction of this kind of strabismus should be based on the standard of daily life.
If the operation over correction, such as oblique surgery for internal oblique, or internal oblique surgery for oblique, postoperative diplopia may also occur. Mild diplopia does not need treatment, if necessary by the three in front of a prism, can not stand again when the surgical correction of diplopia.
12 anesthesia for strabismus surgery
Can be used in surgery of adult patients with local anesthesia, relatively simple and safe. For pediatric patients with strabismus surgery (usually less than 12 years old) with general anesthesia, with a certain risk. Parents should follow the doctor's advice in conjunction with the children with systemic examination and preoperative diet, it is recommended to go to the hospital for the implementation of specialized technical strength of the need for general anesthesia strabismus surgery.
