Evaluation of a Relative Afferent Pupillary Defect using the RAPDx~R Device Before and After Treatment in Patients with Optic Nerve Disease

摘要

We evaluated the amplitude and latency scores in the RAPDx? device together with other-ophthalmic examinations, before and after treatment in four patients with optic nerve disease. In all patients, the visual acuity (VA) and visual field (VF) after treatment was resolved. Both scores after treatment were lower, with reduced laterality-based differences in VA and critical flicker fusion frequency (CFF). Even after treatment, 3 patients had laterality-based differences in cir-cumpapillary retinal nerve fiber layer thickness (cpRFNLT). Both scores for evaluation of RAPD by RAPDx? correlated with subjective examinations and were useful for evaluation of the efficacy of treatment.
