Background: Laser photocoagulation for diabetic Maculopathy has changed little since ist introduction at the early seventies. Fixation of the potentially moving eye is controlled visually. The localization of the areas which can be treated is judged by the comparison of the fundus with the external fluorescein angiography. A novel digital ophthalmoscope provides continuous high-resolution color or infrared imaging and provides flourescein angiography overlay. The system compensates for eye motions and allows localization of 532nm laser treatment. Besides, exclusion zones can be defined.

Methods and patients: The system was tested regarding imaging, accuracy and reproducibility of eye movement compensation. Initial experience of laser treatment in eyes determined to have Diabetic Maculopathy is reported.

Results: Visualization of the fundus on the screen is possible with sufficient quality. The fluorescein angiogram overlay was possible and and allowed definition of areas to be treated.as well as exlusion zones. The compensation of eye movements could be verified.

Discussion: The NAVILAS device allowed imaging, image overlay to diagnostic imaging, and precise delivery of laser photocoagulation. Such a device can be useful for more accurate and safer laser treatment in macular edema.
