In testing visual acuity, if the patient is unable to identify any letters on the Snellen chart, you should next test for the ability to?

Correct. In patients who cannot identify the largest letter on the Snellen chart, test the patient’s ability to identify the number of fingers displayed at a distance of 1 foot (1/3 meter) from each eye (with the other eye occluded). If the patient cannot count fingers, test the patient’s ability to identify the direction of your hand movement, as you move it back and forth and up and down at 1 foot (1/3 meter) from the eye (“hand movements vision”). If the patient fails, test the ability to identify a light shined at the eye from a distance of 1 foot (“light perception vision”). If the patient fails, label vision as “no light perception.”
Incorrect. Good guess, but there is a step before this. Try again!
Incorrect. This test is not performed. Try again!
Incorrect. Good guess, but this is the lowest level of visual acuity.
