TrueT/F – If the patient cannot see the “Big E” on the screen, you stop checking Visual Acuity and move on with the exam.
False: You will then see if the patient can see Hand Motion (HM), if NO, you move on to Light Perception (LP). If YES, then you move on to Counting Fingers (CF) by moving away from the patient approx. 1 Foot at a time until they can no longer see how many fingers you are presenting. (i.e. CF @ 4 FT)

Exam Skills: How to check pupils and an APD
https://morancore.utah.edu/basic-ophthalmology-review/perform-the-pupillary-exam/
https://morancore.utah.edu/basic-ophthalmology-review/relative-afferent-pupillary-defect-rapd/When checking for an APD in a patient with strabismus, it is important to ensure that the light is shined directly into the pupil of each eye. This may mean that you have to change the angle in which the light shines into each eye.Patient should look at distance at a nonaccommodative target. A really large letter that is easy for them to read is okay. Or have them look at a large image or object in the distance.
Quiz Yourself:

1. You are checking the pupils of a patient who is coming in for a glasses update. In the light the pupils are 3 mm and 4 mm , right and left eyes, respectively. In the dark, the pupils are 4mm bilaterally. The left pupil does not seem to constrict when light is shined in it. Does this patient have a relative afferent pupillary defect?Answer: No, this patient has a nonreactive pupil. You can check for a relative afferent pupillary defect in a nonreactive pupil, by checking for an APD by reverse.
2. List three reasons why a pupil may be nonreactive.Answer: The pupil has been dilated pharmacologically (i.e. drops were already placed in the eyes or there was a chemical or medicine that caused dilation.) The patient may have a pupil sphincter defect due to traumatic mydriasis. The patient may have had severe ocular inflammation that caused posterior synechiae. (The pupil is adhered to the anterior lens capsule.) The patient may have a cranial nerve 3 palsy. The patient may have Adie’s tonic pupil, which is a defect in the parasympathetic nerves supply to the pupil.
3. Can glaucoma result in a relative afferent pupillary defect?Answer: Yes, if there is asymmetric glaucoma and one eye is more severely affected by glaucoma resulting in more severe optic atrophy.
