Plusoptix GmbH is a German company located in Nuernberg. Based on the research work at the university of ophthalmology in Tuebingen/Germany Plusoptix has acquired special expertise in the research and development of binocular videoretinoscopy. As a result, international patents were appointed and transferred into products. One of these products is an autorefractor to screen infants and pre-school aged children to detect amblyopia. Other devices measure binocular accommodation in real time and pupil dynamics in photopic, scotopic and mesopic conditions.
The Plusoptix autorefractor uses a binocular video retinoscopy technique to measure refraction data, accommodation and pupil size. This technique illuminates the retina with infrared light from one meter away and records the reflected light with a video camera. A computer programme evaluates the recorded pictures in real time and displays the results on the monitor immediately.
