Touch Diagnostics Launches OKN+™ iPhone App for Visual Deficits as an Indicator of Neurodegenerative Disease

San Diego, CA, Feb 23, 2010 - Touch Diagnostics (TouchDx) launched today a new class of medical diagnostic iPhone applications for use by healthcare practitioners to assess and monitor neurodegenerative disease. The first of which is OKN+™, a medical diagnostic suite of assessments to detect visual deficits and includes three Optokinetic Nystagmus tests and the Red Desaturation test.

OKN+™ offers three different iPhone based Optokinetic Nystagmus tests that provide the clinician with increased diagnostic sensitivity and functionality previously impossible with yesterday’s handheld striped ribbon and handspun drums. OKN+™ is a much needed technological advance and sterile alternative to the old drum and ribbon. Optokinetic Nystagmus, commonly known as OKN, is the eye movement elicited by the tracking of a moving field.


OKN+™ also provides the Red Desaturation Test, which is used to assess for optic nerve pathology as an early indicator of neurological field defects. The disruption in color perception results in reduced vividness of saturated colors, particularly red. Red desaturation can be associated with multiple sclerosis, glaucoma, diabetes, Parkinson's and Alzheimer's disease.

“The OKN+™ iPhone app is a convenient tool that helps me diagnose eye movement abnormalities, localize problems in the visual pathways, and identify other visual perceptual difficulties. Touch Diagnostics brings the forefront of electronic applications to my practice and increases the diagnostic sensitivity of my clinical exam,” Jeffrey Bennett, MD, PhD, Professor of Neurology and Ophthalmology, University of Colorado, Denver.

"Touch Diagnostics is making it possible for healthcare professionals to maximize efficiencies in healthcare delivery using technologically advanced, patient friendly tools”, said Brent Gutekunst, CEO, of Touch Diagnostics. "We have aligned our organization with some of the brightest minds, in various disciplines of medicine, to develop iPhone based state of the art medical diagnostics that will cost effectively revolutionize healthcare delivery.”

Founded in 2009, Touch Diagnostics (TouchDx) has pioneered the development of a new class of applications that utilize smartphone technologies for medical testing & evaluation. The company develops applications focused on leveraging the convenience and technical capabilities of the iPhone to further quantify medical assessments, increase diagnostic sensitivity and yield better health outcomes.
