Adults can have strabismus surgery, but they also have to meet the appropriate indications before they can have strabismus surgery. Surgery can be considered if the strabismus is a constant, common strabismus with a large magnitude and is felt to affect the aesthetics or the ability to see. After surgical correction, the eye position can be returned to the correct position, and most patients have better results. However, in the case of paralytic strabismus, the strabismus is caused by nerve paralysis and muscle paralysis due to recent fatigue and decreased resistance of the body. In addition, paralytic strabismus should also exclude the problem of intracranial tumor. If intracranial tumor is excluded, first observe for about 6 months, and if there is no change, then choose surgery to correct it.
