There are different types of corneal lipid seen in dogs. These include breed related, keratopathies, pannus, episcleritis and degenerative corneal lipid seen in elderly dogs. Cyclosporin has been recognised as a drug that can ‘stabilise’ corneal lipid and in many cases stop it from progressing. It is also been recognised that topical cortisone drops can worsen corneal lipid, so it is ideal to treat keratitis cases with the minimal frequency that controls the inflammation, and use concurrent Cyclosporin. In severe cases where vision is affected or ulcers are not healing quickly, a diamond burr can be used to remove some of the corneal lipid and encourage corneal ulcers to heal.
