| dc.description.abstract | The study was conducted on 45 dogs presented for the signs of ocular diseases. Thirty dogs with blindness or other ocular signs were subjected to complete ophthalmic examination. Samples for ocular cytology and bacterial culture were collected from 10 healthy and 15 dogs presented for superficial ocular affections. The cause of acute blindness was chronic renal disease (4), ehrlichiosis (8), multicentric lymphoma (3), ivermectin toxicity (2), sudden acquired retinal degeneration (1), acute glaucoma (1) and canine distemper (1). Chronic glaucoma (2), progressive retinal atrophy (2) and diabetic cataract (1) were the causes of chronic blindness. Ophthalmoscopic examination showed retinal detachment, optic disc cupping, retinal atrophy or degeneration, increased ocular pressure and lens opacification. Anterior uveitis was diagnosed in 5 patients. Corneo-conjunctival cytology showed primarily squamous epithelial cells in healthy dogs. There were numerous neutrophils in conjunctivitis, increased number of lymphocytes in stromal keratitis and keratinized epithelial cells with neutrophils, lymphocytes, plasma cells and eosinophil in kerato-conjunctivitis. Ocular metastasis was observed in two dogs with multicentric lymphoma. Ocular masses in two dogs were due to squamous cell carcinoma and transmissible veneral tumor. Staphylococcus spp and bacillus spp. were cultured from 6 of 10 healthy dogs. Eyes of all the dogs with conjunctivitis, kerato-conjunctivitis, stromal keratitis, lymphoma, squamous cell carcinoma and transmissible venereal tumor yielded Staphylococcus spp. consistently. Pseudomonas spp. along with Staphylococcus spp. was cultured from 2 of the 5 kerato-conjunctivitis affected dogs. Antibacterial sensitivity of bacteria cultured from superficial ocular affections showed higher sensitivity for chloramphenicol, amikacin, moxifloxacin and gatifloxacin. | |
