Symptoms and Prevention and Treatment Methods of Infectious Keratoconjunctivitis
Infectious Keratoconjunctivitis
(Agricultural Wealth Network) [Characteristics]
Commonly known as "pink eye," it is an acute infectious disease of ruminant livestock caused by Haemophilus and Rickettsia. The damage is limited to the eyes only, causing obvious inflammatory changes in the conjunctiva and cornea, photophobia and tearing, conjunctival redness and congestion, and mucous or purulent discharge from the eye corners; in a few cases it forms corneal nebula, leukoma, or causes blindness. This disease often occurs in the high-temperature summer and autumn seasons when temperatures are higher and mosquitoes and flies are more abundant, and in environments with poor air circulation and high ammonia concentration.
[Prevention and Treatment]
1. Isolate affected sheep, and clean and disinfect the pen promptly.
2. Wash the eyes with 2-5% boric acid water or light saline or 0.01% nitrofural, and after drying, apply eye ointments such as erythromycin, chloramphenicol, tetracycline, 2% yellow mercuric oxide, or 2% cortisone to the eyes.
3. Penicillin or chloramphenicol plus 2 ml dexamethasone and 1 ml 0.1% adrenaline can also be mixed and applied to the eyes 2-3 times/day.
4. For those with corneal opacity or cataract, instill Boyun San; or inject 500,000 units of penicillin plus 10 ml of whole blood from the affected sheep subcutaneously into the eyelid; or inject 5 ml of 500,000 units streptomycin solution into the supraorbital foramen, once every 2 days.
