title: Cyclic strabismus.
abstract: An unusual age of presentation of cyclic strabismus, which became constant in a relatively short period of time without a previous history of surgery, trauma, or strabismus, is reported. The mechanism of cyclic strabismus is still unknown; however, most cases are treated successfully with strabismus surgery. Cyclic strabismus is distinct from other rhythmic diseases in that peripheral manipulation of the target organ results in resolution of the deviation.
