First measure the size of pupil for both eyes under photopic condition. After which observe the shape of the pupil.

Next, measure the size of the pupil of both eyes under scotopic condition

After which, do the consensual reflex test by placing a pentorch below the eye of the subject. The pupil of the eye where the pen torch would constrict. Observe the consensual reflex on the other eye.

Following which, do the swing flashing test by placing the pentorch on one eye and count till 3. Next place the pen torch on the other eye and count to 3. Keep alternating the light on both eyes. Observe the constriction and dilation of the pupil.

Lastly, do the accomodation test. Get the subject to focus on something at far. Place an object in front of the subject. Ajust the position of the object from front to back, and back to front. Observe the pupil constriction and dilation while accomodating.

The results should be recorded in the PERRLA form.
