Systems and methods for detecting and classifying retinal microaneurysms. The method including: receiving a time sequence of fluorescein angiography input images; generating a binary map of hyperfluorescent elements in the input images; determining which hyperfluorescent elements in the binary map are microaneurysms, by grading each against a combination of morphological metrics; classifying each of the detected microaneurysms as leaky or not leaky, the classification having: identifying an outer ring mask surrounding the detected microaneurysm in the binary map; identifying parenchyma in the outer ring mask using a fluorescence intensity determination; determining a rate of change of fluorescence intensity of the identified parenchyma over time; and classifying the detected microaneurysm as leaky where the rate of change is positive and not leaky where the rate of change is negative or zero; and outputting the classifications of the detected microaneurysms.
