Occlusion, glasses, prism therapy, miotics, fusional vergence stimulation, plus more surgery are required frequently in various combinations for a high percentage of patients whose strabismic eyes are straightened by surgery. Amblyopia is a serious sequelae befalling children who are dismissed following satisfactory surgery. Their best possible postoperative status is monofixation (absence of bifixation), despite having straight eyes. Unless they alternate fixation, amblyopia is prone to either occur or recur. Also, either a gradual change in motor innervation to the extraocular muscles or a cicatricial scarring process may subtly cause subsequent strabismus. Hence, despite straight eyes postoperatively the surgeon's responsibility continues.
