What is considered the only standardized DIRECT observation test of saccades?

• A. NSUCO oculomotor test
• B. DEM
• C. King Devick
• D. Pierce saccade test

Answer: (A)

The key idea is recognizing what counts as a direct, standardized observation of how the eyes move during a task. The NSUCO oculomotor test is designed to be a standardized, direct-observation instrument for saccadic function and related ocular motor skills. It provides a consistent protocol and scoring that the examiner uses while watching eye movements, fixation, and any head movement, with normative data to guide interpretation. Because it relies on the clinician observing and rating the actual eye movements during the task, it stands as the standardized direct observation test of saccades in this context.

Developmental Eye Movement focuses on timing and errors during reading-like sequences and isn’t a direct observation of saccadic movements recorded by the examiner. King-Devick involves rapid naming of numbers to screen saccades and processing speed rather than an examiner’s standardized observation of ocular motility. The Pierce saccade test exists historically but isn’t used as a standardized, widely accepted direct observation tool in the same way NSUCO is.
