Abstract
Significance: A Nintendo(®) 3DS™ game can reliably test monocular near acuity, stereopsis and color without the need for occlusion patches or goggles. Purpose: We developed dynamic, forced-multiple choice games to measure monocular near acuity, color vision and stereopsis on the autostereoscopic barrier screen of the Nintendo 3DS gaming system. Methods: In an institutional review board-approved study, pediatric and adult patients and normal subjects performed routine patched near visual acuity, Ishahara's color test and Stereo Fly tests. Then each subject performed a two-phase orientation and testing game, "PDI Check", on a Nintendo 3DS. Results: Forty-five patients aged 5-60 years completed the routine and Nintendo near tests, resulting in positive, consistent, discriminatory correlation functions. From ROC curves, referral criteria were determined to separate poor from fair-to-normal monocular acuity with 98% sensitivity and 100% specificity, stereoacuity with 80% sensitivity and 97% specificity, and color with 83% sensitivity and 100% specificity. Conclusion: The Nintendo 3DS game PDI Check can provide consistent near vision testing via a dynamic, randomized method that does not require goggles for stereo, and does not require patching to assure monocular testing.
