I decided to take Maddie to the vet yesterday. Her vet diagnosed her with an ulcer on her eye, NOT dry eye. That was the diagnosis from an ER vet I took her to one Sunday when she had a similar problem. Before, the ER vet gave me antibiotic drops and told me to use Natural Tears daily. The problems seemed to go away. However, as stated in my OP the problem came back. I am giving 1/4 in. strip of Cyclosporine once a day and using Vetropolycin ointment 3 times a day.

We go back Monday.
Are ulcers common in Yorkies? She seems to have this problem in the same eye.
