About Optos Plc

Optos plc is a leading retinal imaging company. Our vision is to be recognised as the leading provider of retinal diagnostics through leveraging our unique wide-field imaging technology. Both eye and non-eye diseases often first exhibit in the periphery of the retina. These are very difficult to detect clinically with conventional examination equipment and techniques. Optos’ devices produce ultra wide-field, high resolution images of approximately 82% of the retina, something no other device is capable of doing in any one image. The images provide optometrists and ophthalmologists with enhanced clinical information which facilitates the early detection, management and treatment of disorders and diseases evidenced in the retina such as retinal detachments and tears, glaucoma, diabetic retinopathy and age-related macular degeneration. Retinal imaging can also indicate evidence of non-eye or systemic diseases such as hypertension and certain cancers. Optos has a range of medical devices that support different customer segments and patient levels: the P200 device is concentrated on wellness screening carried out by optometrists and ophthalmologists in primary care; the P200C device is designed to meet the need for more exacting clinical imaging capabilities and standards in secondary care within the ophthalmology market and at optometric practices that are clinically managing a patient base with advanced ocular disease; and the P200MA device supports retinal specialists, working primarily with a diabetic patient base, in the medical care market through an advanced medical angiography procedure. Optos’ technology provides an unequalled combination of wide-field retinal imaging, speed and convenience for the practitioner and patient resulting in more targeted treatment regimes and improved patient outcomes. 75% of all blindness can be treated or prevented if diagnosed early enough and our Optos technology supports this objective.
