Dear,our dog is diagnosed with keratitis.Swabs are not done because vet said that there is no need. PLR +,nebulae present in both eyes,threat test positive,OS:STT:21, OD:STT:22 mm/m, Fundi B.O. Corneal reflex +,fluorescent test negative.She was on Uniflox and Uniclophen drops for 9 days and on Dexametazon neomicin drops and Tacrolimus cream for 7. We are worried because nobody can tell us what is the trigger.How can we find out that and what test to do to check is it autoimmune or genetic?

It sounds like your dog has had a complete ocular workup, and the treatments appear appropriate for the diagnostic findings. I agree that the problem may be autoimmune or genetic. There are also a few viral or infections caused by tick-borne disease that could cause chronic keratitis in dogs. I would recommend discussing this with your veterinarian. Often dogs will need long-term use of steroids or other immune-altering drugs to control immune-mediated disease.
