Abstract
The present study was conducted on 86 clinical cases of ocular disorders in cattle (Indigenous and cross breed), sheltered at Shree Pannalal Gaushala, Mandore, Jodhpur, Rajasthan and also among those cattle presented during health camps organized by the Department of Surgery and Radiology, College of Veterinary and Animal Science, RAJUVAS, Bikaner, Rajasthan, from August 2018 to December 2018.
Of the ocular diseases encountered, eyelid affections 6.97% (n= 6), eyeball affections 4.65% (n=4), conjunctival affections 13.95% (n=12), sclera affection 1.16% (n=1), corneal affections 30.23% (n=26), third eyelid affections 4.65% (n=4), uveial affections 2.33% (n=2), lens affections 5.81% (n=5), orbit affections 4.65% (n=4), nasolacrimal duct blockage 2.33% (n=2) and blindness due to unknown origin 23.25% (n=20) were recorded.
Age wise incidence of ophthalmic affections were highest in the cattle of age group 2-8 years (51.16%, n=44). A significantly higher percentage of ophthalmic affections were recorded in the males (58.14%, n= 50) than females (41.86%, n=36). A significantly higher percentage of ophthalmic affections were recorded in indigenous cattle (69.76%, n= 60) than crossbreed (30.24% n= 26).
Haemoto-biochemical examinations of all the animals under study were carried out. All the parameter were within normal range in all cases except in one case of corneal ulcer with opacity (an ocular manifestation of theleriosis), in which low hemoglobin (Hb 3%), and low RBCs values (1.3×106/µL) were recorded.
14 cases of corneal affections were treated surgico-therapeutically successfully except one case of corneal ulcer with opacity in which animal

died within 3 days. All the cases of corneal affections had significantly higher STT 1 value. 5 cases of cataract were treated by Extra-capsular cataract extraction technique, of which 3 cattle were positive menace and pupillary light reflex test as evidence of aphakic vision. Eye of one operated cattle eye get infected and endophthalmitis developed, another animal not had vision but have clear cornea.
18 cases of dermoid, out of which scleral dermoid (n=1), cornioconjunctival dermoid (n=17)) were treated surgico-therapeutically. Six cases of ocular tumour were treated surgico-therapeutically successfully. Out of 6 cases of ocular, 5 were squamous cell carcinoma and one case was bovine papillomatosis which were confirmed by FNAB and histopathological examination. Other ocular affection like 3 cases of eyelid laceration, 3 cases of ocular abscesses, 4 cases of conjunctivitis, 2 cases of nasolacrimal duct obstruction, 2 cases of Chemosis, 2 cases of orbital myiasis, 2 cases of uveitis, 2 cases of chronic traumatic proptosis and 2 cases of chronic exophthalmia treated surgico-therapeutically, Out of those cases, one case of orbital myiasis animal died and one case of uveitis not recovered. 20 cases of blindness were diagnosed as blindness due to unknown origin, could not diagnosed confirmatively due to unavailability of advance diagnostic procedure.
