OKN+ is a medical diagnostic suite that currently includes two assessments used by healthcare professionals to detect visual deficits. OKN+ provides the Optokinetic Nystagmus (OKN) Test; a welcome and sterile alternative to yesterday’s drum and ribbon. OKN testing is useful in detecting subtle abnormalities or asymmetries in saccadic or smooth pursuit eye movements. Additionally, for patients who cannot communicate or in whom factitious blindness or malingering is suspected, OKN can assist in determining whether there is an intact visual pathway.

OKN+ also provides the Red Desaturation Test, used to assess for optic nerve pathology. The OKN+ Red Desaturation Test can be used as a diagnostic assessment tool in patient populations such as multiple sclerosis, glaucoma, diabetes, Parkinson's and Alzheimer's disease.

Does Not Work - Stick to Cloth

This app simply fails to function - repeatedly stalling and quitting. It seems likely that even if the video played properly, that it would be too small on an iphone to work reliably as an OKN drum or strip. Perhaps under ideal circumstances - or with an ipad - it could replace a cloth strip. Myself, I will continue to use the trusty cloth. It is portable, energy efficient, and just the right size - although I would have liked to add another tool to my swiss army knife of a phone.


Great program works for me sensitive to touch but once on no problems whatsoever


OKN crap

I agree. This app crashes EVERY time I do anything but hit play with the default setting.. Speed it up, program crashes.. Switch to patterns... Crashes..
They need to fix it or change it's name to OK Crash+
