Abstract
A 2.5 year old male horse was presented to Teaching Veterinary Hospital, VCRI, Namakkal, India with the history of lacrimation, impaired vision and progressive corneal opacity in left eye. Clinical examination revealed movement of a thread like worm in the anterior chamber of the eye. For removal of the worm, affected eye was prepared for surgery by deep sedation with xylazine hydrochloride. Then general anaesthesia was done with Ketamine hydrochloride and maintained by isoflurane. After induction, worm was removed by needling technique. Topical antibiotic and steroid were administered postoperatively to check secondary bacterial infection and corneal opacity. After surgery, the vision was restored and corneal opacity was reduced gradually. Morphologically, the worm was identified as Setaria spp. This is a common case in India due to vector prevalence.Asian J. Med. Biol. Res. September 2017, 3(3): 398-404
Highlights
Ocular setariasis is a disease of equine resulting from ectopic parasitisim caused by Setaria spp. under the genus Setaria (Gangwar et al, 2008)
The objective of the present study is to describe a detailed surgical procedure of needling technique for removing Setaria spp. from anterior chamber of affected eye of a horse and to observe the recovery of corneal opacity
The horse had the history of continuous lacrimation and movement of worm in the affected eye for 7 days
Summary
Ocular setariasis is a disease of equine resulting from ectopic parasitisim caused by Setaria spp. under the genus Setaria (Gangwar et al, 2008). The parasite can be found in various organs such as heart, lung, spleen, kidney, uterus, oviduct, ovary and urinary bladder, as well as in the contents of rumen, reticulum and abomasum (Mandal et al, 1994). The parasite is transmitted by mosquitoes through the blood stream (Varma et al, 1971). The parasite exhibits migratory behavior in unnatural hosts such as horses, donkeys or human beings and immature worm can invade eye (Sreedevi et al, 2002; Tuntivanich et al, 2011) through the vascular system (Townsend, 2013). The erratic movement of the worm within the anterior chamber of the eye may cause severe
