The present disclosure discloses a method and apparatus for acquiring information. An implementation of the method comprises: acquiring a fundus image; introducing the fundus image into a pre-trained pathological classification model to obtain pathological classification information, wherein the pathological classification model is used for characterizing correspondence between a pathological area image contained from the fundus image and the pathological classification information, and the pathological classification information comprises at least one of diabetic retinopathy classification information and diabetic macular edema classification information; and establishing output information based on the pathological classification information. This implementation concurrently acquires diabetic retinopathy classification information and diabetic macular edema classification information from the fundus image, and may make full use of the correlation between diabetic retinopathy and diabetic macular edema in diagnosis to effectively improve the accuracy of diabetic retinopathy classification and diabetic macular edema classification in the process of computer aided diagnosis.
