1, the concept of strabismus and classification strabismus is a kind of visual axis separation state, that is, when the two eyes look at a target, one eye looks at the target, the other eye deviates to the side of the target. The reason is the abnormal development of extraocular muscles, imbalance of regulation and convergence force, and incomplete central fusion function, which makes both eyes spread out or converge out of control, resulting in strabismus. If the eye deviates medially (i.e., nasal side), it is called internal strabismus, and if it deviates laterally, it is called exotropia (strabismus). Upward or downward strabismus is called superior or inferior strabismus. Strabismus is fixed in only one eye, called constant strabismus; while some people can alternate between the two eyes, the other eye to one side, called alternating strabismus; there are people who usually do not see strabismus, when the concentration or fatigue strabismus, called intermittent strabismus, the danger is the same as constant strabismus, and can develop into constant strabismus. In addition to strabismus caused by inflammation, injury, B vitamin deficiency or imbalance in the strength of a pair of antagonistic muscles, refractive error, dysfunctions of the combined regulating and collecting movements, fusion insufficiency and amblyopia, it is also related to the following factors: (1) genetic factors suggest that when both parents have poor vision and refractive error, their children are prone to strabismus; (2) artificial feeding and mixed (3) both eyes look at the near object for a long time, both eyes are bound to produce strong convergence, and over time, the muscles that bear the eyes inward are especially developed, while the muscles that turn outward become relatively weak, and the two eyes approach inward, forming strabismus. The influence of television: television educational programs, children’s theater, knowledge world, animation city and other columns, so that children consciously or by parents urged to look at the eye & rdquo;, some children watching television even forget to eat, eye overwork. The influence of the game machine: socially popular variety of game cards, is another interesting program to attract children, the screen changes very quickly, adults feel very blinding, many children a play is several hours. The impact of the Internet: children play the most online games; followed by online chat. Some children even spend the whole night in the Internet cafe eyes extremely tired, vision is seriously reduced. The influence of excessive learning burden: some parents have too high expectations of their children, in addition to completing school assignments, but also to learn calligraphy, painting, music, etc., so that children are tired of coping all day, not much time for activities and rest, eyes and body overwork. (4) Lack of eye care knowledge. Both schools and parents lack knowledge about eye physiology and health care. Eye care exercises are just a formality. The early detection and treatment of strabismus cannot be achieved either. The key to preventing strabismus is early detection, early diagnosis, early treatment and preventing children from looking at objects that are too close to them. (1) Strengthen physical exercise, eye health care Primary schools should add eye health care courses to strengthen the education of children’s eye physiological health knowledge. Hold “ parents eye care knowledge training courses” to draw parents’ attention to children’s strabismus. Strabismus can be a routine item in the physical examination of children before entering kindergarten or school, and if strabismus or amblyopia or refractive error is found, it should be given corrective treatment in time. (2) Avoid children to watch TV or play games for a long time Parents should selectively let children watch some useful programs. The time should not be too long, generally half an hour at a time, if you need to watch continuously, you must take a break for 10 min to 20 min. (3) Early correction of refractive error Children with myopia or hyperopia, it is advisable to dilate the pupil for an early eye exam and wear appropriate glasses. In recent years, many ophthalmology literature reported that most children with strabismus not only have combined refractive error, but also have incomplete stereo vision development. (4) Early treatment of amblyopia Because amblyopia and strabismus can affect each other. Only by improving the visual acuity of the amblyopic eye and treating amblyopia at an early stage can strabismus be prevented. (5) Early correction of strabismus Early correction and training of strabismus, such as no organic eye disease, should be carried out early visual acuity and gaze function exercise; also can be used stereoscope or the same vision machine for eye position correction training, to prevent the formation of strabismus. If strabismus still exists after conservative treatment, strabismus correction should be performed as early as possible. In order to establish perfect binocular vision, strabismus correction should be performed in childhood in order to achieve functional healing. The age of completion of stereoscopic function is generally 6 years, so correction of strabismus before school age is ideal. According to the literature, the standardized sensory integration therapy was used to treat the visual-motor imbalance and incoordination in children with cerebral palsy (CP) strabismus with an overall efficiency of 85.2%, which provides a new method for the treatment of strabismus in children under 3 years old with CP who do not cooperate in the conventional strabismus treatment. In conclusion, the prevention and treatment of strabismus in children are attracting more and more attention, and only by doing a good job in the prevention and health care of children’s eyes and reducing the incidence can we ensure the healthy growth of children.
