What do you need? You could possibly get overall mean intensity or color, LAB or HSV color, area, perimeter, standard deviation, skew, kurtosis, uniformity (entropy), area fraction of blood vessels, number of spots/defects, etc. Plus there's all those things that regionprops measures that I didn't even mention.
There's nothing built in to MATLAB to do sclera vessel detection, so I think you should look at the published literature to find a suitable algorithm, then code it up in MATLAB. Start your search in section 20.5 here:Vision Bibliography. If you need help with MATLAB code (syntax, error messages, program flow, etc.) then come back and attach your images and m-files.
