1.What is strabismus? Strabismus refers to the fact that both eyes cannot look at the same target at the same time, and when one eye looks at the target, the other eye becomes oblique. Sometimes parents find that the child’s head is sideways and the two eyes are squinting together to gaze at the object (squinting), that is not strabismus, it is generally called lateral vision, mostly due to bad habits or refractive error. 2, the harm of strabismus First of all, it affects the aesthetics, which is the most intuitive understanding of strabismus by patients and their parents. Secondly, some types of strabismus that occur in early childhood may also lead to the formation of amblyopia. The most important thing is that strabismus can lead to damage or loss of binocular vision. Binocular vision, as the name implies, is the ability to see with both eyes at the same time. Individuals with dysfunctional binocular vision can have an impact on depth perception and fine manipulation, thus limiting the patient’s career choices. Therefore, it is important to treat strabismus as early as possible to restore part of the stereopsis function as much as possible under the premise that the patient’s strabismus degree is stable. 3.How to treat strabismus Completely refractive adjustment of internal strabismus does not require surgery. It needs to be treated with glasses. For the rest of strabismus, surgery is required when the indication for surgery is reached. 4.Safety of strabismus surgery Strabismus surgery is an external eye surgery, which is relatively safe. There is no relationship between strabismus surgery and vision, and patients who should wear glasses should wear glasses after surgery. 5.Whether general anesthesia affects patients General anesthesia is required for strabismus surgery in children and some special adults, and general anesthesia has no effect on intelligence. Patients under general anesthesia need to fast from food and water for 8 hours before surgery, but do not therefore, eat excessively when you can eat before and after surgery. 6. Other All strabismus patients do not cover their eyes after surgery (this is the case in our hospital, not involving other hospitals), and basically do not affect their daily life. The most common early postoperative complication in strabismus patients is postoperative nausea and vomiting, which is related to the pulling reflex of the eye muscles and can mostly be relieved by itself, and a calm mind can effectively reduce the incidence. There is no special contraindication for postoperative diet.
