What Does Apd Mean in Ophthalmology

An Afferent Pupillary Defect

Can you have an APD in both eyes?

In case if both pupils do not show a similar response to the light stimuli, shone in one eye at a time, the patient will be diagnosed with RAPD or Marcus Gunn pupils. off note if the condition is bilateral and symmetrical, there will not be a RAPD but bilateral APD.

What is the difference between APD and RAPD?

RAPD vs APD In literature, and clinical practice, RAPD, and APD, or afferent pupillary defect, may be used synonymously. However, RAPD is technically describing the relative response of one pupil so there is no such thing as bilateral RAPD and, for a RAPD to exist, the damage must be asymmetric between the eyes.
