Strabismus drugs are drugs used to correct misalignment of the eyes. Agents used in the treatment of strabismus (misalignment) and resulting amblyopia (lazy eye) include paralytic agents such as botox used on extraocular muscles, topical autonomic nervous system agents to alter the refractive index in the eyes, and agents that act in the central nervous system to correct amblyopia. == Surgery == (詳細はextraocular muscles (where they attach to the globe). ''Resection'' surgery removes tissue in order to stretch a muscle, increasing its elastic force; ''recession'' moves an insertion so as to reduce stretch, and so reduce elastic force; ''transposition'' moves an insertion “sideways”, sacrificing one direction of muscle action for another; ''posterior'' ''fixation'' relocates a muscle’s effective insertion to a mechanically disadvantageous position. All are kinds of compensatory impairment. Pharmacologic injection treatments, in contrast, offer the possibility of directly increasing or decreasing contractile muscle strength and elastic stiffness, as well as changing muscle length, without removing tissue or otherwise compromising orbital mechanics.〔 Spherical lenses and ''miotic'' eye drops can provide relief in some types of horizontal strabismus by biasing the neural link between ''convergence'' (orienting the lines of sight for near objects) and ''accommodation'' (focusing), and prism lenses can relieve ''diplopia'' (double vision) by refracting the visual axis, but these treatments don’t address the underlying muscular imbalance, and are not further considered here.
