Generally this should work. Use graythresh and im2bw to make a mask of white dots and then use bwconncomp to count them.
cc = bwconncomp(bw, 4)
cc.NumObjects

cc.NumObjects would be the count of dots.
so one way to display it is:
disp(cc.NumObjects)

That's exactly what my Image Segmentation Tutorial does. Find it in my File Exchange Replace the standard coins demo image with yours and change the threshold value and you should be all set.
