Note to Editors

Optos plc

Optos plc is a leading and rapidly growing medical technology company for the design, development, manufacturing and marketing of devices that image the retina, the light-sensitive area at the back of the eye. Optos' platform technology is the Panoramic200 Scanning Laser Ophthalmoscope device - known as the P200. In a quarter of a second the P200 device produces a high resolution image of up to 200 degrees or approximately 82 percent of the retina in a single capture. The image - branded the optomap^® Retinal Exam - provides eye care practitioners with clinically useful information that facilitates the early detection of disorders and diseases evidenced in the retina, such as glaucoma, diabetic retinopathy and age-related macular degeneration. Retinal imaging can also indicate evidence of non-eye or systemic diseases such as diabetes, hypertension and certain cancers. The Company has regulatory clearance (CE and FDA 510(k)) to market a second device - P200MA. Optos’ technology provides an unequalled combination of wide-field retinal imaging, speed and convenience for both practitioner and patient and can help save sight and save lives. Optos is incorporated in Scotland under the Companies Act 1985 with registered number SC139953. The Company maintains its Registered Office at Queensferry House, Carnegie Business Campus, Dunfermline, Scotland KY11 8GR United Kingdom.
