Abstract
An apparatus and method is disclosed that enables an existing handheld eye imaging device to do direct measurement on images taken from the patient eye. In a preferred embodiment, a reticle is arranged in the handheld eye imaging device so that a reticle image is superimposed on the object image. In addition to allowing the user to make measurements, the reticle superimposed eye image can also be used to align the eye with the handheld eye imaging device, be used for registering images taken at different times, and also be used for finding previously recorded points on the images for comparison purposes.
