title: Adult-onset cyclic esotropia and optic atrophy.
abstract: A 37-year-old man developed periodic esotropia with 4-day cycles. He was unique because of his age, negative family history for strabismus, bilateral optic atrophy, and absence of light perception in the deviating eye. Adult-onset cyclic esotropia in a blind eye is reported. This afferent defect may lead to secondary changes in the central nervous system, and fusional potential is not necessary for cyclic esotropia to occur.
