This isn't a traditional camera, but instead uses a low power green and red lasers to simultaneously scan your retina in less than a second. It doesn't require dilation and provides the doctor an internal 200 degree view of the retina.
We offer the Optomap retinal screening service for $35.00. It is generally not covered by insurance unless it is being used to actively follow disease.
