    OCULAR AFFECTIONS IN ANIMALS WITH PARTICULAR REFERENCE TO CORNEAL MELANOSIS.
    (CSKHPKV, Palampur, 2019-07-23) Charbiwala, Murtaza Khozema; Tyagi, S. P.
    The present study was carried out to diagnose, evaluate and manage corneal melanosis in animals; evaluate the diagnostic and therapeutic management of other ocular conditions; and to record and study the regional occurrence of ocular affections in animals. The study was conducted on the clinical cases of animals presented to the Department of Veterinary Surgery and Radiology, DGCN College of Veterinary and Animal Sciences, CSKHPKV, Palampur, India from April, 2018 to March, 2019. The overall occurrence of ocular affections in animals was found to be 10.26 per cent; species-wise incidence was higher in dogs; sex-wise in males; ocular anatomy-wise in cornea. Among different animals, dogs were more commonly affected with corneal melanosis and the condition was mostly associated with Brachycephalic ocular syndrome with Pugs being most-commonly affected breed and males showing a higher incidence than females. Various characteristics like degree, depth and pattern of ‘Corneal melanosis’ were recorded and evaluated. Management of corneal melanosis was conducted with medical and surgical methods often in conjunction. Topical steroids, Cyclosporine and tacrolimus largely proved to be good in halting progression of corneal melanosis but not in reducing the exiting melanosis. Diamond burr superficial keratectomy (DBSK) proved to be an easy, effective and fast technique for surgical debridement of corneal melanosis. DBSK along with partial conjunctivectomy and diathermy of limbal vessels adjacent to melanotic area proved good in minimizing re-pigmentation of cornea following surgery. Parotid duct transposition proved to be a good option to lubricate eyes in cases of refractory keratoconjunctivitis sicca. Pre-emptive correction of macropalpebral fissure and medial lower entropion in young dogs by Medial canthoplasty prevented the development of corneal pigmentation in susceptible dogs. Post-operative diligent topical therapy was found to be extremely important for good outcomes.
