Abstract

Reproducibility and Normative Values of the Parameters of a New Hand-Held Digital Pupillometer

Ken Asakawa and Hitoshi Ishikawa

We evaluated the intra-examiner reproducibility and determined the standard values of pupil parameters using the PLR-3000 pupillometer (NeurOptics Inc). Generally good reproducibility was obtained, except for the T75 parameter. The standard values may be useful to distinguish various neurological abnormalities in clinical practice.
