A Clinical Case from the Archives : 11/06/2007

This dog has had keratoconjunctivitis sicca, unresponsive to topical cyclosporine which, as you can see, has a nice wet ocular surface after a parotid duct transposition. It does, however, have some white deposits in the tear film and on the corneal surface. What are these and what might be done to reduce them?

Here’s another picture of the same eye. These are calcium deposits from the saliva now replacing tears on the ocular surface. Treating topically with EDTA can stop them depositing on the cornea but this is a recognised problem after the surgery.
