My dog has pannus. Do I need to use eye drops in both eyes for life?

Updated On September 23rd, 2025

Pet's info: Dog | German Shepherd | Male | unneutered | 3 years old | 80 lbs

Our German Shepherd male dog at just over a year old developed a red spot on his left eye. It was diagnosed as pannus. After only 1 week of 2% cyclosporin in the eye he had fully recovered. No more red spot. Since then we have been administering a drop in each eye everyday but are now doing a drop in each eye every 2nd day. All looks fine. We don't know if he had pannus in the other eye because no symptoms came into view. Should we still be putting the drops in his right eye. Any thoughts?

Hello, and thanks for your question. Pannus is typically a bilateral condition (although symptoms can be worse in one eye), and once diagnosed, treatment is for life to minimize the recurrence of further symptoms. I would recommend continuing treatment in both eyes indefinitely unless your vet is directing otherwise. Hope this helps!
