comitant strabismus
Pronunciation: KOM-ih-tant
A type of strabismus where the deviation remains constant in all directions of gaze, indicating normal extraocular muscle function.
Full Definition
Comitant strabismus, also known as nonparalytic strabismus, is characterized by equal deviation measurements in all nine cardinal directions of gaze, with full extraocular muscle range of motion in both eyes. This is the most common form of strabismus in children and typically results from abnormal binocular vision development rather than muscle weakness or restriction. The term 'comitant' derives from the Latin meaning 'accompanying,' as the eyes move together normally despite being misaligned. Proper identification of comitant versus incomitant strabismus is crucial for determining surgical approach and prognosis.
Usage
Usage note: Distinguish clearly from incomitant; avoid confusing with accommodative strabismus.
