Testing Eye Movements NSUCO Pursuit & Saccade Testing These testing standards grew out of the work done at Southern California College of Optometry in the early 1990's. Maples and coworkers found that the SCCO method for scoring eye movement performance put emphasis on the least reliable aspect of eye movement grading: the "ability" measure. For standard scores, the average score for a given age is usually set to a 100 (this would be equal to the 50th percentile). It can be administered by psychologists, neuropsychologists, occupational therapists, physical therapists, regular and special educators, and diagnosticians who are interested in examining the visual-perceptual status and visual-motor integration skills of adolescents and adults. specific tests of reading eye movements (e.g., Developmental Eye Movement test, photo-electric oculogram) Include actual scores and results from all tests, procedures, measurements, and scales administered to demonstrate the level of impairment to visual functioning. Time: 5 minutes. Clinical tests to explore and assess eye movement's performance in dyslexia have been developed and widely used by clinicians.

The Developmental Eye Movement (DEM) test was developed on the assumption that poor eye movement control is a major cause of reading difficulties. However, while the DEM test ratio has been reported to correlate with horizontal saccadic eye movements, there have been no published comparative studies of the DEM test and objective eye movement measures. Sound Patterns: Rhythm, Rate, and Sequencing Discrimination. Abstract. Test of Developmental Eye Movements •Speed and Accuracy of Saccadic Eye Movements •Comparison of horizontal to vertical saccadic ability •Normative data from age 6.0 to 13.11. For more information see Laukkanen, Eliason, Kenison & Oland, Optom and Vis. -(13.11 is considered to be adult level) A special type of eye movement, rapid eye movement, occurs during REM sleep. The developmental eye movement (DEM) test determines the speed with which a series of numbers can be recognised and verbalised with accuracy and is purported to provide an indirect evaluation of saccadic eye movements. Dr. Grades: K-3. Fix-and-Follow is a simple and popular method for assessing early development of visual perception in infants, currently however, there is no formal reproducible method for grading the capacity of fix-and-follow. Bernell's exclusive DEM™ test provides an objective method of assessing fixational and saccadic activity during reading and non-reading tasks.
