Paper Abstract

We propose a self-evaluation of visual field using free-focus retinal scanning laser display technology based on Maxwellian-viewing optics. The developed device was the combination of commercially available smartphone with built-in laser pico-projector and newly developed additional optics to realize Maxwellian-view and eye-safety. Movie with flying and fixed gazing spot was displayed on the subject’s retina for evaluation. The non-recognition areas were found by the self-evaluation not only at the Marriott blind spot but at other area corresponding to the abnormal visual field in the Amsler chart test related to the inflated upstream blood vessel due to the retinal vein occlusion.
