Evaluation at UK Deployed Field Hospital Demonstrates Advantages of
Vision-Sciences' EndoSheath(R) Technology for Bronchoscopy

Study Conducted in Afghanistan Reported System's Ease-of-Use, Safety and
Potentially Life-Saving Benefits of Sterile, Disposable Micro Barrier

ORANGEBURG, N.Y., Sept. 9, 2013 (GLOBE NEWSWIRE) -- Vision-Sciences, Inc.
(Nasdaq:VSCI), a leading provider of unique flexible endoscopic products
utilizing its proprietary sterile disposable EndoSheath^® technology, today
announced positive results from a three-month evaluation completed in 2012 by
the British Army at Camp Bastion, a deployed field hospital in Afghanistan.
The research evaluated the efficacy and utility of our flexible bronchoscope
with EndoSheath technology and its rapid, simplified cleaning routine versus
conventional bronchoscopes, which require specialized, complicated
disinfection processes between each use.

The abstract, entitled "Evaluation of a disposable sheath bronchoscope system
for use in the deployed field hospital," was published first online on August
28, 2013, in J R Army Med Corps. Study authors Lieutenant Colonel Andrew
McDonald Johnston et al concluded that a disposable single-use sheath reduces
the risk of cross-contamination and avoids the need for prolonged liquid
immersion, sterilization or the increased cost of completely disposable
single-use bronchoscopes. Furthermore, they found that a bronchoscope system
that can be cleaned without sending it out of the deployed hospital alleviated
physicians' concern regarding availability and should therefore be part of the
equipment table in the field hospital. Complex endoscope sterilization systems
required to ensure adequate cleaning and sterility of bronchoscopes are not
part of the equipment found at a deployed UK field hospital. After use, these
systems have to be sent to another facility, and the round trip, including
sterilization, typically takes 1-3 days, creating a potential risk of not
having a bronchoscope available at short notice.

In a deployed environment, bronchoscopy can play an important role when caring
for patients who have suffered penetrating trauma as they often develop
complications, such as bleeding from the airways, mucus plugging, and
pulmonary infections. The three physicians who used the scope ten times during
the three-month period of evaluation were all experienced in bronchoscopy,
including two pulmonary and critical care physicians and one anesthetic
trained intensivist. The EndoSheath technology was used predominantly in
patients with high velocity fragment or bullet wounds to the thorax to clear
blood from the airways. In one instance, this was found to be life-saving, and
in another, it significantly shortened the length of time for ventilation and
allowed early extubation. The system also demonstrated its utility in
performing percutaneous tracheostomy.

"These findings demonstrate the positive impact our EndoSheath technology can
have by providing sterile bronchoscope technology when caring for critically
ill patients, particularly in an austere environment, such as a field
hospital," stated Howard Zauberman, Interim Chief Executive Officer of
Vision-Sciences. "In these settings, safety, portability, and ease-of-use are
paramount when responding to critical cases, and we believe the results of
this study establish the advantages in using our sterile, disposable
technology over conventional equipment."

Vision-Sciences' proprietary EndoSheath technology provides a sterile,
disposable, microbial barrier between the bronchoscope and patient, including
a disposable biopsy/suction channel. This design means that our bronchoscopes
never come in direct contact with the patient at any point during the
procedure, which in turn allows for a simpler, more-efficient cleaning and
disinfection routine between examinations.

According to the study, the time required to set up the bronchoscope and
monitor was less than 10 min on all occasions. This included the cleaning and
disinfection steps prior to insertion of the bronchoscope into the disposable
sheath. After use, the cleaning and disinfection steps were easy to carry out
and did not require very much time.
