Management of traumatic ulcerative keratitis in a Red Serow

Abstract

Red Serow Capricornis rubidus is an elusive herbivore native to the montane forests of the Himalaya. Currently it is categorized as ‘Vulnerable’ in the IUCN Red List and placed under Schedule I species of the Wildlife Protection Act, 1972. A serow was presented with complaints of mild inappetence, irritability, sporadic scratching of head over the enclosure barrier and serous ocular discharge from the left eye. Based on detail clinical examination, the animal was diagnosed with unilateral conjunctivitis, corneal oedema, and ulcerative keratitis. A combination of Xylazine @ 1.5mg/ kg body weight and Zolatile® (zolazepam and tiletamine) @ 2.5 mg/kg body weight was used to chemically restrain the animal, followed by auriculo-palpebral nerve block using 1 ml of 2 % lignocaine hydrochloride. The affected eye was adequately cleaned with isotonic sterile Normal Saline solution (NSS). Combination of 0.5 ml of ceftriaxone and 0.5 ml of flubiprofen was injected into upper and lower palpebral conjunctiva. The cornea and the third eyelid flap were carefully sutured using 5-0 and 3-0 Vicryl, respectively. Finally, tarsorrhaphy was done using 2-0 nylon. Post-operative care consisted of an antibiotic regimen of Cephalaxin @ 20 mg/ kg body weight b-i.d-twice in a day for seven days along with probiotic supplement (Vizylac®) and Vitamin A capsules (Aquasol A®) orally once daily for the next 30 days. The animal showed complete recovery within 30 days of proper treatment, monitoring, care and management.
