A new random-dot stereotest using a 3D display and infrared oculography has been found to assess stereopsis objectively in children aged more than 3 years, according to an article published in the November issue of Investigative Ophthalmology & Visual Science.
The study involved 56 children, 38 with various visual impairments and 18 with normal vision. The random-dot stimulus was presented on an autostereoscopic display, which allows viewing of color 3D images. The stimulus recognition was objectively assessed using infrared photo-oculography. The overall accuracy of the test was found to be 95%.The new test setting was developed by Daniel Mojon, MD, FEBO, and the stimulus presentation algorithm was developed by Xiaoyi Jiang, PhD.
