Abstract
Background:
Optic nerve head drusen (ONHD) are a relatively uncommon finding with an estimated prevalence of anywhere from 0.3% to 2%. Reports of relative afferent pupillary defects (RAPDs) associated with ONHD are scarce.
Case Report:
A patient with an RAPD was found to have ONHD as the only apparent etiology of the RAPD. The various diagnostic tests relevant to the case, the differential diagnosis, and the pathological features of ONHD are discussed.
Conclusions:
It is important for the clinician to consider an RAPD as a possible pathological feature of ONHD--especially with an asymmetric presentation.
