Manchester Royal Eye Hospital and Second Sight announce global surgical first with Manchester patient

Initial tests on 80-year-old with no central vision show that 'bionic eye' treatment allows patient to see the outline of people again

ray and pauloManchester Royal Eye Hospital and Second Sight Medical Products, Inc. ("Second Sight" or "the Company") (NASDAQ: EYES), today announce that they are delighted by early stage tests on the world's first ever dry Age Related Macular Degeneration (AMD) patient to receive the Argus II 'bionic eye'.

Paulo Stanga, Consultant Ophthalmologist & Vitreoretinal Surgeon at the Manchester Royal Eye Hospital and Professor of Ophthalmology and Retinal Regeneration at The University of Manchester, says that initial screening tests on 80-year-old Ray Flynn, from Audenshaw in Manchester, have shown that he has perception in his central vision for the first time in many years.

With the Argus II system switched on, Mr Flynn is able to make out the outline of people and objects even with his eyes closed - thus proving that he is not using any of his remaining natural vision to identify the shapes and outlines.

The procedure to implant Mr Flynn took place on June 16 in a four-hour procedure. Mr Flynn's system was turned on for the first time on July 1. Tests carried out the same day consisted of the patient looking at a computer screen and identifying black and white patterns, at different orientations. The patient's ability to correctly identify the direction of the lines and the difference between the diagonal and horizontal lines shows that the Argus II device is providing central visual function that did not exist prior to the patient being implanted.

It is expected that with practice and rehabilitation, Mr Flynn's vision will continue to improve.

Professor Stanga says: "Mr Flynn's progress is truly remarkable. He is seeing the outline of people and objects very effectively.

"Mr Flynn is the first patient to be implanted with Argus II as part of a trial we are doing that aims to establish whether blind patients with total central vision loss due to dry AMD can benefit from an artificial retina - the Argus® II Retinal Prosthesis System. Currently, indications for use of commercially available retinal prostheses are limited to patients with the rare disease Retinitis Pigmentosa.

"As far as I am concerned, the first results of the trial are a total success, and I look forward to treating more dry AMD patients with the Argus II as part of this trial. We are currently recruiting four more patients to the trial in Manchester.

Dry AMD is a much more common disease than Retinitis Pigmentosa (RP). Worldwide, an estimated 375,000 people suffer from severe RP1, compared to 20 to 25 million who have AMD2.

According to the UK patient group The Macular Society, the dry form of AMD affects 44,000 more people per year in the UK3.

Professor Stanga, who is also Director of the Manchester Vision Regeneration (MVR) Laboratory at the National Institute for Health Research (NIHR)/Wellcome Trust Manchester Clinical Research Facility, says: "On behalf of the Manchester Royal Eye Hospital, we feel privileged to be conducting the world's first study into retinal implants for patients with AMD. This technology is revolutionary and changes patients' lives - restoring some functional vision and helping them to live more independently.

"The dry form of AMD is a common but untreatable condition. In the western world, it is the leading cause of sight loss. Unfortunately, with an ageing population, it is becoming more common. We are initially limiting our study to the dry form of AMD, and if successful, perhaps we will subsequently look into recruiting patients with the advanced and scarred wet form of AMD."

Gregoire Cosendai, VP of Europe for Second Sight Medical Products, says: "The difference between patients with dry AMD and patients with RP is that the AMD patients retain some peripheral vision. RP patients with severe disease have no peripheral vision. This is why we have focused on treating RP patients first. This study will aim to establish whether the retention of some peripheral vision in dry AMD patients with severe sight loss - functionally blind patients - can benefit from artificial vision in their central visual field as well as using their remaining peripheral natural vision. This is totally groundbreaking research."

Minister for Life Sciences, George Freeman said: "This ground-breaking research highlights the crucial role of the NHS as a test bed for 21st century medicine. In investing over £1 billion a year into the National Institute for Health Research, we provide trials like this one with the state-of-the-art facilities and researchers needed to translate scientific advances into real benefits for patients."

Notes

Second Sight gained European approval (CE Mark) for the Argus II system in 2011 and United States FDA approval in 2013. The Argus II system remains the first approved retinal prosthesis treatment in the world. The Argus II has now been implanted in over 130 patients. Several patients have been using the system for more than seven years, which shows the long-term reliability of the device. Argus II has been the subject of over 20 peer-reviewed articles, including the most recent one, "Long-Term Results from an Epiretinal Prosthesis to Restore Sight to the Blind" by Ho et al in Ophthalmology, 2015:311 (http://www.aaojournal.org/article/S0161-6420(15)00415-7/abstract)..

The Argus II works by converting video images captured by a miniature camera housed in the patient's glasses into a series of small electrical pulses that are transmitted wirelessly to electrodes on the surface of the retina. These pulses stimulate the retina's remaining cells resulting in the corresponding perception of patterns of light in the brain. The patient then learns to interpret these visual patterns to regain some visual function.

Dry AMD is more common than the 'wet' type. Dry AMD affects 85% of AMD patients. Dry AMD usually develops slowly and causes gradual loss of central vision, but doesn't affect peripheral vision.

About the Argus® II Retinal Prosthesis System

Second Sight's Argus II System provides electrical stimulation that bypasses the defunct retinal cells and stimulates remaining viable cells inducing visual perception in individuals with severe to profound retinitis pigmentosa. The Argus II works by converting images captured by a miniature video camera mounted on the patient's glasses into a series of small electrical pulses, which are transmitted wirelessly to an array of electrodes implanted on the surface of the retina. These pulses are intended to stimulate the retina's remaining cells, resulting in the perception of patterns of light in the brain. The patient then learns to interpret these visual patterns, thereby regaining some visual function. The Argus II is the first artificial retina to receive widespread approval, and is offered at approved centers in Canada, France, Germany, Italy, Netherlands, Saudi Arabia, Spain, Switzerland, Turkey, United Kingdom and the United States.

About Second Sight

Second Sight Medical Products, Inc. was founded in 1998 to create a retinal prosthesis to provide sight to patients blinded from outer retinal degenerations such as RP. Second Sight's mission is to develop, manufacture, and market innovative implantable visual prosthetics to enable blind individuals to achieve greater independence. Second Sight's Argus II Retinal Prosthesis is approved in the United States, Canada, Europe, and Saudi Arabia, and a trial is currently underway to test the safety and efficacy of the Argus II in patients with Dry Age-Related Macular Degeneration (AMD).

Second Sight is also developing the OrionTM I Visual Cortical Prosthesis to restore some vision to individuals who are blind due to causes other than preventable or treatable conditions. Second Sight's headquarters are in Sylmar, California, and its European Headquarters are in Lausanne, Switzerland. For more information, visit www.secondsight.com.
