Pupil dilation lengthens exams, but also increases the cost of the exams. The plusoptiX photoscreener is a noninvasive digital infrared device linked to software. It takes multiple photographs in 3 different meridians in just a few seconds. The plusoptiX screens both eyes simultaneously for refractive errors, pupil size, and gaze deviation in patients as young as 6 months. Results are displayed immediately as a pass or refer. Pupil size, corneal reflexes, and refraction are measured and compared with referral criteria; if readings are outside age-based limits, a refer recommendation is displayed
The researchers who presented at the American Association for Pediatric Ophthalmology and Strabismus 38th Annual Meeting, conclude that a normal plusoptiX result, combined with normal alignment/motility evaluation and normal visual acuity, has a 98% negative predictive value for ophthalmologic pathology.
