It was observed that there was a purulent conjunctivitis in the left eye and there was a mobile structure under the membrane nictitans after the examination. A drop of local anesthetic was dripped into the eye, and the mobile structure was removed with the help of a forceps. This removed structure was taken into the solution of 70% alcohol on suspicion of parasite. Both the extracted material and the blood samples were sent to the Department of Internal Medicine, Afyon Kocatepe University, Faculty of Veterinary Medicine for evaluation and it was evaluated with parasitologist.
