Strabismus is a common eye disease. Many people think that it is just unattractive, and it does not matter whether it is treated or not, or it does not matter when it is treated, but these views are incorrect. So, what are the dangers of strabismus? First of all, strabismus can lead to amblyopia. The eye that is often located in the oblique position does not receive the normal image stimulation, resulting in amblyopia and low vision, which is often severe and difficult to treat, so early correction of strabismus is essential for the treatment of amblyopia. In addition, both eyes are located in an ortho-position and have very precise stereo vision when looking at things together, which is an advanced visual function possessed by this advanced organism. This function is lost when strabismus occurs, and if strabismus persists, it can never be restored when the sensitive period of visual development is exceeded, so the earlier strabismus is treated, the better. Finally, the appearance of strabismus also has a negative impact on the physical and mental health of the patient. In children, it can cause introversion, sensitivity, and low self-esteem, and in adults, it still has an impact on interpersonal communication and work, causing a decline in mental health. Therefore, strabismus is not only unattractive, but it is very important to cure strabismus for both children and adults.
