摘要：
An ophthalmic machine is provided for obtaining and diagnosing fluorescence images of the retina. An excitation light having first wavelengths (e.g., between 430 nm and 490 nm) is scanned onto the retina. Light emitted by the retina, when illuminated thereby, is filtered to block light of the first wavelengths and to pass light of second (higher) wavelengths. A second filter selects a component of the passed light having second (e.g., green) wavelengths, and a third filter selects a component of the passed light having third (e.g., red) wavelengths. First and second detection means receive light transmitted by the first and second filters, respectively, and provide detection signals indicative thereof. The detection signals are processed to provide one or more images of the retina, said images of the retina comprising at least a color fluorescence image of the retina.
