[Clinical classification of incomitant strabismus].

Based on study of etiology, pathogenesis, clinical course, results of treatment of 489 patients aged from 1 till 73 years old with incomitant strabismus and integration of literature data clinical classification of incomitant strabismus was developed. Classification considers type and degree of extraocular muscle impairment (paralysis, palsy, pseudoparalysis, atypical forms), localization of damage (III, IV, VI cranial nerves, concurrent nerve damage), level of damage (cranial, orbital, combined), etiology and pathogenesis (local or systemic disease), age of manifestation (congenital, early and lately acquired), clinical manifestations (direction of globe deviation, forced head position, amblyopia, orbital fractures and soft tissue entrapment), presence of binocular diplopia (in primary or all gaze directions, in secondary gaze directions, without diplopia).
