Abstract :
An exclusive literature on ocular dermoids in crossbred Indian cattle is currently unavailable except for
sporadic reports. Medical records of past four years (2012-2015) were investigated for evaluation of ocular dermoids
in crossbred Indian cattle. The overall incidence of ocular dermoids was found to be 0.345% (5/1451). All the animals
were less than five months of age. Based on anatomical location, four types of ocular dermoid were noticed either
alone or in combination, both unilaterally and/or bilaterally. Unilateral presentation was common and the ventrolateral corneoconjunctival dermoid predominated by type. Bilateral coexistence of both ventrolateral corneoconjunctival
dermoid and medial canthus dermoid in a single eye was noticed in a calf and is believed to be the first report of this
kind. Histopathological evaluation of the ocular choristomas showed hair shafts and bulbs in addition to sebaceous
and sweat glands. Postoperative evaluation showed adequate response to the surgical treatment adopted without any
subsequent recurrence. Following surgical excision, a calf with bilateral corneoconjunctival dermoid repaired by superficial keratectomy and conjunctival flap developed iris prolapse, iridocyclitis and phthisis bulbi and subsequently
underwent unilateral enucleation of eyeball. The acquired data was compared and evaluated with literature reviews.
