Answer

For small degrees of anisometropia in SWS, full optical correction of both eyes or at least full correction of the refractive difference between the eyes is desirable. In higher degrees of anisometropia or in children who develop strabismus, measures to prevent amblyopia and treat strabismus should be initiated. Anisometropic amblyopia may require occlusion therapy along with correction of the refractive error. In some patients, a contact lens may be required to treat fusion difficulty due to aniseikonia.

Any significant strabismus that is still present after the completion of amblyopia therapy, refractive lens correction, and orthoptics is treated best with eye muscle surgery. Avoiding or carefully cauterizing the dilated subconjunctival and episcleral vessels during strabismus surgery is important to prevent bleeding and scarring, so that the conjunctiva and anterior sclera are preserved for future glaucoma procedures.
