Title Filters vs. Polarizing Glasses for RAPD Measurement
Creator Michael L. Rosenberg; H. Stanley Thompson; Randy H. Kardon
Affiliation (MLR) Scotch Plains, NJ; (HST) Iowa City, IA; (RHK) Iowa City, IA
Subject Relative Afferent Pupillary Defect; Neutral Density Filter; Polarized Filter; RAPD Measurement
Description We measured the relative afferent pupillary defect in 23 patients using two techniques: a) hand held neutral density filters and b) a pair of glasses holding crossed polarizing filters in front of each eye. Overall, both techniques gave similar answers. For very small asymmetries of pupillary input the polarizing glasses seemed to be especially useful because small changes in filter density could be quickly and accurately dialed in, so that the balance point could be handily bracketed.
