Abstract：A microscopic hyperspectral imaging device was used to study the normal and diabetic retinas of rats. The microscopic hyperspectral images of retinas from normal,diabetic and medicative rats were collected and processed. Some transmission spectral curves of outer nuclear layer of retina were extracted and analyzed. The results showed that there are three characteristic spikes in the spectral curves between 400 and 800 nm from the outer nuclear layer,and the heights of the characteristic spikes at 113 band were altered obviously between the normal and diabetic retinas. In addition,the spectral curve of the diabetic retina changes gradually to the normal spectrum curve after treatment by the LCVS1001. The experiment result showed that the microscope hyperspectral imaging device could be used to study the changes in spectrum characters and physical chemistry composition of the diabetic retina.
