Pathogen

Canine Thelaziasis (conjunctival sucking nematode) parasitizes the conjunctival sac and nictitating membrane of the eye, and is a milky white fine nematode. The males are 7 to 13 mm long and the females are 12 to 17 mm long. The disease is transmitted by flies as an intermediate host. The epidemic is seasonal (the optimum temperature is around 28 C).

Symptom

At first I saw conjunctival hyperemia, moist eyeballs, fear of light and tears, followed by viscous secretions. The conjunctival sac and nictitating membrane are densely packed with small grain-like vesicles. The sick dog rubbed his eyes and face with his toes from time to time, and rubbed his cheeks and forehead repeatedly, making it unbearable. The upper and lower eyelids are frequently opened and closed, the eyeballs are obviously sunken, the cornea is cloudy, the eyelids are glued in the later stage, the vision is reduced, and even ulcers are formed (no reports of death).

Treatment

For sick dogs, use a syringe with the needle removed to draw 1 to 2 ml of 5% Levamisole Hydrochloride Injection, slowly drip into the eyes from the corners of the eyes of the sick dog, gently knead the upper and lower eyelids for 1 to 2 minutes, open the upper and lower eyelids, and use tweezers to sterilize the wet gauze or Use a cotton ball to gently wipe the attached worms until they are all removed, and then slowly rinse the affected eyes with saline, wipe them dry with cotton wool, and apply tetracycline or erythromycin eye ointment.
