Monocular vision loss (due to cataract, corneal clouding, optic nerve or retinal disorders, or various other entities) may cause sensory (deprivation) esotropia. Conditions preventing clear and focused retinal images and symmetric visual stimulation must be identified and remedied promptly, if possible, to prevent irreversible amblyopia. If surgery or botulinum toxin injection is indicated for strabismus, it is generally performed only on the eye with a significant vision deficit.
