Abstract
In the present study, a retrospective analysis of the ophthahnic records in equines at the Department of Surgery was done from 2013- 2015 to find out the incidence, distribution and pattern of ocular affections along with clinical outcome of various therapeutic and surgical management undertaken. A total of 196 horses with different clinical conditions were reported from August-2013 to February-2015. Out of these, 56 horses were reported to have ocular affections with overall incidence of 28.57%. Breed wise occurrence of ophthalmic affections revealed maximum incidence in Marvvadi (30%) followed by crossbred (27%), Kathiawadi (25%) and Sindhi (18%). Sex wise distribution indicated that more males (73%i) were affected than females (27%). Out of 56 horses, the overall incidence of ocular setariasis (61.1!%. n=33) was highest followed by affections of eye lid (11.11%, n=6), cornea (07.40%, n=4), uvea (07.40%, n=4), conjunctiva (05.55%, n=3), anterior chamber (05.55%), n=3) and globe (3.70%, n=2). The cases of ocular affections were diagnosed on the basis of detailed clinical and ophthalmologic examinations. Clinical entities like corneal opacity, corneal oedema, coi-neal ulcers, chemo.sis and uveitis (normal uveitis and equine recurrent uveitis) were treated by appropriate therapeutic regimens and others like equine eyeworm, sarcoids, eyelid lacerations and ocular neoplasia were subjected to appropriate surgical manoeuvres. The standard medical management for conditions like chemosis, corneal ulcers, hyphema was effective, but in equine recurrent uveitis, ocular symptoms revealed improvement in cases presented early, but in chronic cases, the therapy was not successful. In ocular setariasis, B-mode ultrasonography using linear probe (10- l8MHz) was found appropriate diagnostic modality to visualize setarial worm movement in anterior chamber as well as vitreous. Paracentesis of anterior chamber for removal of intraocular parasite through a modified clear corneal stab incision at the limbal margins using 2.8 mm pointed tip 45° angled keratome was found more effective than BP blade incision of cornea.
