Relative Afferent Pupillary Defects (RAPD)
Pupil diameter under different light conditions
Efferent Pupillary Defects
The days of using the subjective and difficult to perform “swinging flashlight test” are over! Screen and assess retina or optic nerve disorders with ease!
Simple to use and operate
Reproducible measurement results in less than a minute by a technician
Stimulates each eye with light
Records both the right and left pupil responses simultaneously to calculate the magnitude of the relative afferent pupillary defect in light log units
Provides very accurate measurement of pupil diameter for refractive surgery screening and planning (LASIK and IOLs) under: scotopic, low mesopic, and high mesopic conditions.
Detects efferent pupillary defects including: parasympathetic nerve deficits (e.g., oculomotor nerve, brainstem, Adie’s pupil).
Sympathetic nerve defects (e.g., Horner’s syndrome) and pharmacological causes of unequal pupils.
Portable, battery operated binocular pupillometer

Patient data may be uploaded via USB
Can be used as a hand-held device (for supine patients) or mounted onto a stand
RAPD graphically displayed immediately after the measurement
Normative range provided
Internal memory for storing more than 1,000 records
