Interrater and test-retest reliability of pursuits and saccades.

Pursuit and saccade testing have long been used by optometry to evaluate oculomotor efficiency. The literature is not consistent as to an acceptable grading system for these tests. An oculomotor test is described which grades pursuit and saccade skills in four major areas of function. Interrater and test-retest reliability data are reported which indicate that this test has clinically acceptable grading consistency. Implications for the field of optometric measurement are discussed.
