Background:
A novel digital ophthalmoscope provides continuous high-resolution color or infrared fundus imaging and provides flourescein angiography overlay. The system compensates for eye motions and allows localization of 532nm laser treatment. Besides, zones that should not be coagulated can be defined.
Methods:
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 zones that shoul not be coagulated. The compensation of eye movements could be verified.
Conclusions:
The NAVILAS device allowed imaging, fluorescein image overlay, and precise delivery of laser photocoagulation. Such a device can be useful for more accurate and safer laser treatment in diabetic macular edema.
