Spasm of the near reflex associated with organic disease.

Spasm of the near reflex is characterized by transient attacks of convergence, accommodation, and miosis. It is usually observed in young individuals and considered functional. We studied seven patients with spasm of the near reflex who had associated neurologic disorders or head trauma. Two patients had posterior fossa abnormalities (cerebellar tumor, Arnold-Chiari malformation), two patients had pituitary tumors, one patient had a vestibulopathy, and two patients had a history of antecedent head trauma.
