Infantile convergence-evoked nystagmus.
A case of convergence-evoked nystagmus in a healthy 15-month-old boy is presented. This is clinically demonstrated to be induced by fusional convergence, and not related to accommodative, tonic, or proximal convergence. The lack of neurological or ophthalmic abnormalities supports the classification of a "congenital" type of this rare phenomenon. A differential diagnosis is also discussed.
