WEST VALLEY VISION CENTER OFFERS REVOLUTIONARY MODALITY FOR RETINAL DISEASE DETECTION TO PATIENTS

-- Optomap™, retinal exam becoming standard of care throughout the world --

Goodyear, AZ, October 29, 2003- - West Valley Vision Center is one of only a handful of eyecare practices in Arizona to offer its patients the Optomap™ retinal exam (Optos North America). This revolutionary modality captures and analyzes an image of virtually the entire retina, for the early detection and management of eye disease. Since Optos first introduced the Optomap exam, nearly 250,000 exams have been conducted worldwide, diagnosing serious eye conditions - such as diabetic retinopathy, retinal detachments and macular degeneration - that could have otherwise gone undetected.

The Optomap retinal exam takes a computer-generated image of the retina, which can be immediately evaluated by the doctors at the West Valley Vision Center. There is no pupil dilation, no eye drops, blurred vision or sensitivity to light. The Optomap retinal exam is a simple, quick and important way to maintain good eye health.

"The Optomap increases the quality of the retinal exam by allowing us to view almost the entire retina at the start of the exam, which can have important implications, not only for detecting eye disease, but also in detecting and managing other medical conditions such as diabetes. We recommend all of our patients have this exam, which has already detected issues in some of our patients which could have otherwise gone undetected."

Due to its clinical, patient and practice benefits, the Optomap retinal exam has the potential to become part of the standard of care in practices throughout the world. In addition to its many clinical and patient benefits, the Optomap also allows doctors to spend more time with patients, and provides a permanent photo-documentation that can be sent to a patient's primary care physician or specialist if needed and can also be used to educate patients.

"One of our first patients screened with the Optomap retinal exam came in for his/her annual eye exam and was not experiencing any symptoms or problems. "The Optomap allowed us to see a very early onset of macular degeneration, (THIS could be replaced with another condition such as diabetic retinopathy, retinal detachment, etc) which may not have been detected using other conventional methods. As a result, we were able to properly diagnose the problem, treat it early and, prevent any loss of vision for the patient."

Various studies have concluded that the Optomap exam, is effective in increasing the quality of a clinical evaluation of the retina in a primary eyecare setting; is a reliable tool for the detection of retinal disease; and has sensitivity similar to the current gold standard - clinical evaluation through a dilated pupil. This study also concluded that the Optomap exam detected three times more retinal abnormalities than a clinical evaluation through an undilated pupil. A separate study sponsored by the American Optometric Association in 2000 showed that 52% of patients presenting for an eye exam are NOT dilated.

About Optos

The Optos modality was developed as a patient-friendly examination tool by Douglas Anderson, founder and vice chairman, Optos, after his son Leif lost the use of an eye when a retinal detachment was detected too late. It incorporates the latest in scanning laser ophthalmoscope (SLO) technology, using low-powered red-green laser beams to capture an image of virtually the entire retina on an "Optomap", a permanent digital record that gives clinicians a view of the retina that is unprecedented with prior technologies.

Optos North America, the wholly-owned subsidiary of Optos plc, is headquartered in Marlborough, MA. Optos plc and the company's development center are located in Dunfermline, Scotland. Visit the Optos website at www.optos.com
