Abstract
Subconjunctival abscesses are rarely reported in animals. This paper gives a comprehensive review of subconjunctival abscess cases in bovines presented over a period of seven years. A total of 18 cases were presented. Out of which, 17 were calves while an adult cow was also affected by subconjunctival abscess. The signalments of the cases were studied from the history. All the cases were presented after a period of 6 days to one month. The etiology was mostly unknown but all the calves were sent for grazing. The clinical signs in these cases included blepharitis, epiphora, drooping of the eyelids and chemosis. The conjunctiva of the lower eyelid, upper eyelid, lateral canthus, bulbar conjunctiva, or the nictitating membrane was involved. Confirmatory diagnosis was made by fine needle aspiration of the swelling. Ultrasonography revealed an anechoic to hypoechoic collection of echogenic fluid with poorly defined borders. Bacillus species, E. coli, Klebsiella species, Clostridium species and Staphylococcus aureus were isolated from these cases. Treatment included lancing of the mature abscess under auriculopalpebral and retro-bulbar nerve block using 2% lignocaine, draining of the pus and lavaging with normal saline and painting the abscess cavity with Tincture iodine. Antibiotic and NSAID eye drops were prescribed post-operatively. Systemic antibiotics were also prescribed in selected cases. Prognosis was good in all the cases.
