A model designed to demonstrate extraocular muscle paralyses was constructed with some success. Some problems concerning vertical gazes were unable to be resolved rendering the demonstrator of limited use. An accompanying discussion on extraocular muscle pareses and paralyses reviews the muscle's locations, actions, and innervations, and various testing procedures used in the assessment of paretic and paralytic extraocular muscles. Also included is a description of the typical course of a paresis/paralysis and of various paretic and paralytic presentations with associated etiologic and epidemialogic information. Anomalies which mimic or cause extraocular muscle pareses/paralyses are also mentioned briefly.
