TRUE OR FALSE: In order for a GDX or HRT to be performed, the patient must have dilating eyedrops instilled?

Explanation:
Dilation is not required for these imaging tests. GDx and HRT are designed to capture the necessary optic nerve head and retinal nerve fiber layer data through an undilated pupil, so pharmacologic dilation isn’t an absolute prerequisite. In practice, clinicians may choose to dilate if the pupil is very small or if image quality could be improved, but you can perform the tests without dilating. Therefore, the statement that dilation must be instilled is false.
