New instrument helps determine health by scanning eyes

MORGANTOWN, W.Va. (AP) � A West Virginia company is developing an
instrument that will allow doctors and emergency workers to determine
a patient's health by scanning their eyes. 
MD Biotech's ocular scanning instrument identifies and analyzes
attributes of the eye, which is "tightly interconnected with systems
of the body," Chief Executive Officer W.C. Bird said Monday in a news
release. 

"Scientific literature identifies the eye as the one of the most
prominent indicators for various hazards and/or diseases to which
individuals are exposed," Bird said. 

He said instrument can detect a wide range of injuries, illnesses and
physical abnormalities. 

MD Biotech, located in Morgantown, received grants totaling $915,000
from the federal Defense Advanced Research Projects Agency for the
project. The West Virginia High Technology Consortium is helping the
company with prototype design. 

"Military personnel, emergency agencies and medical professionals who
deal in emergency first response and medical care are in critical
need of a rapid, noninvasive and inexpensive technology, such as the
OSI, that monitors personnel and patient health," Bird said.

Soldier Self Care


If soldiers have more tools and science going into combat with them,
the better prepared they will be to survive and help others to
survive when injuries occur. This will give those forces more
�persistence in combat.�

Ocular Scanning Devices

The Ocular Scanning Instrument (OSI) is a project under development
that will allow for rapid identification of warfighters exposed to
certain chemical/biologic warfare agents in a non-invasive manner.
The basic foundation for the project by MD Biotech is that a
portable, lightweight, automated handheld device would be able to
detect and analyze small variations in eye movements and pupil size,
allowing for the recognition of biomarkers induced by exposure to
nerve agents organophosphates/anticholinesterases (anti-AchE),
cyanide, carbon monoxide and botulinum toxin. Typical biomarkers
include: video-oculography; eye movements; pupil size and reactivity
to light; retinal blood vessels; hemoglobin, hematocrit and
platelets; tearing; conjunctival discoloration; and corneal
abnormalities such as clouding, blister formation and ulceration. 

MD Biotech is currently working to characterize specific biomarkers
associated with the aforementioned toxic compounds and their temporal
relationship to the development of clinical symptoms. This
establishment between ocular biomarkers and toxin exposure will be
used to develop algorithms allowing for rapid detection of toxin
exposure, thus rendering an early specific diagnosis that can be used
to initiate Solder Self Care and result in a more rapid return to
combat following toxin exposure.

In the case of organophosphate/anticholinesterase agents, a dose
response curve is being evaluated with respect to degree of miosis
following exposure. This data is being investigated in combination
with other secondary biomarkers to increase the sensitivity and
specificity for the detection of organophosphates and anti-AchE
toxins.

With cyanide and carbon monoxide toxicity, MD Biotech is undergoing
preliminary investigations looking at retinal artery and vein changes
in a rat model to determine specific biomarkers. These biomarkers are
then used to construct concentration response curves along with
secondary biomarkers that will be used to detect cyanide and carbon
monoxide toxicity.

Botulinum Toxin exposure is also under investigation, due to its ease
in production and usage as a bio-weapon. The goal is to develop
reliable biomarkers that are sensitive and specific enough to detect
exposure prior to the delivery of a lethal dose.

The ultimate goal of MD Biotech is to develop not just a hand-held
OSI, but an integrated sensor that would be part of a warfighter�s
field equipment, providing continuous evaluation for possible toxin
exposure and a warring system to alert the solider if an exposure has
occurred. This would allow the soldier to take action to minimize
contact and initiate Solider Self Care.
