On MEM, a shift towards against motion with a bright pink or white reflex indicates what?

• A. Shift towards with motion with brick red reflex
• B. No change in reflex
• C. Brightness decreases with motion
• D. Shift towards against motion with a bright pink or white reflex

Answer: (D)

In MEM, you’re testing how well the eye’s accommodation matches the near-task demand by introducing a minus lens and watching the retinal reflex move as you observe the pupil. A drift of the reflex toward against motion means the eye is accommodating more than the lens demand requires—the reflex appears to move opposite to the direction you’re sweeping. The bright pink or white reflex simply confirms you’re seeing a clear, strong reflex, supporting that this motion strip is real. So this pattern indicates an accommodative lead (over-accommodation) at near. If the reflex shifted toward with motion, it would suggest under-accommodation (accommodative lag); no change would be a neutral response.
