PromptRAPD - definition and differentials
ResponseThe pathologic response that characterizes the RAPD includes the following: 1) the light reaction causes pupil constriction in both eyes when the light shines in the normal eye, and (2) dilatation of the pupils in both eyes when the light stimulus is rapidly transferred from the normal eye to the pathologic eye
