I am trying to picture this as I don't recall seeing this in my own horses. HOWEVER, I have seen a large number of lumps and bumps on the cornia, or the third eye or the eye ball itself, and they are usually white, grey or blue in nature. Can you be more specfic? I almost think this is a light relection that increases the size. If you are not in the sunlight, can you see if this is raised bumps on the lens itself? I really am not sure how to answer until I can get a better handle on the size, placement etc. Does the horses site semmed impaired? Do you see a large number of fly bites near the tear ducts so that this would be a larva issue?
