ABOUT US

When a five-year-old boy was blinded after a regular eye exam failed to spot a retinal detachment, his father made it his life’s work to help eye care professionals by revolutionising retinal imaging. Optos was founded by Douglas Anderson in 1992 with the goal to make a patient-friendly device to quickly capture the entire retina.

The experience of Douglas Anderson is a thread that runs through the company to this day and has resulted in our products being used in nearly 20,000 locations globally. Optomap® shows up to 82% (200°) of the retina in a single-capture, offering unrivalled clarity and Optos is proud to be recognised as the leader in this field.
