Patent ID: 8545022

Claim:
An ophthalmoscope comprising: an illumination device configured to direct an illumination beam onto a background of an eye; an observation device configured to image an observation beam reflected by the eye background onto an image plane; a photosensitive electronic sensor disposed in the image plane and configured to generate a live image of the eye background; a therapy beam source configured to apply therapy beam pulses onto the eye background; and an electronic drive unit, including a computer, operatively coupled to the sensor and configured to evaluate the live image of the eye background in real-time and determine an object-based coordinate system of the eye background based on structures of the eye in the live image, the object-referenced coordinate system being stationary relative to the eye background, wherein the electronic drive unit is further configured to measure positions of the therapy beam pulses, projected through the pupil onto the eye background, relative to the object-referenced coordinate system and store information about the therapy beam pulses applied onto the eye background, the information including the positions of the therapy beam pulses on the eye background.
