Have the patient view a distant target then a near target. Be sure to observe both eyes to confirm the responses are equal and symmetrical. It is important you take a systematic approach to evaluation your patient's pupils. Even if the pupils are unequal you really do not know which is the faulty eye. Or is one more sluggish.
Pupils are of equal size.
Neither pupil reacts when the defective eye is stimulated. There is no direct light response. There is no consensual light response to the contralateral eye. Both pupils react when the contralateral eye is stimulated. Direct light response is present.
