The main goal of correcting strabismus is to restore the visual function of both eyes; strabismus can generally be corrected by general treatment, medication and surgery. 1. General treatment: Correcting amblyopia and diplopia that coexist with strabismus. For example, accurate prescription of glasses or covering the dominant eye of monocular amblyopia can correct slight strabismus; wearing frame glasses and prisms can correct slight diplopia. 2. Drug treatment: refractive internal strabismus can be relieved by taking medication such as pupil dilator and pupil reducer; botulinum toxin A can also be injected into the antagonist muscle of the paralyzed muscle to reestablish the balance between the paralyzed muscle and the antagonist muscle, so as to achieve the effect of reducing or eliminating strabismus. 3. Surgery: For severe strabismus, ocular muscle reduction, rectus muscle shortening, and horizontal muscle vertical displacement can be used to correct A-type or V-type horizontal strabismus without obvious strabismus abnormality. Note that patients with strabismus should seek prompt medical attention for early detection and treatment. In daily life, they should also avoid wrong eye posture and develop good living habits.
