In the study period 9138 numbers of dogs were screened and ocular disease was recorded in 71 numbers of dog. The prevalence of ocular diseases in dog was recorded 0.78%. On the basis of clinical categorization, the highest prevalence of ocular disease was recorded as conjunctivitis (49.29%) and lowest in corneal opacity (7.05%). In the present study, the highest affection of eye was recorded in both eye (45.07%) and highest clinical findings recorded in congested mucous membrane (84.50%. The season wise prevalence of ocular disease in dogs was highest in winter (45.07%) and lowest in pre-monsoon (8.45%) season. In present study sex wise prevalence of ocular diseases were more in male (64.78%) than female (35.22%).Age - wise prevalence was highest in the>3 years – 6 years (29.58%) age group and lowest in below 1 year (4.22%) age group and breed wise prevalence the highest was recorded in German Shepherd (19.72%) and lowest in Boxer (2.82%). The most common species of bacteria isolated were Staphylococcus (22.39%), Streptococcus (19.40%) and Pseudomonas (8.95%) species. More number of coagulase positive Staphylococcus species were recorded. Staphylococcus and Streptococcus species were mostly isolated from conjunctivitis condition and Pseudomonas species were highest isolated from keratitis condition. The sensitivity pattern of the isolates showed highest sensitivity to ciprofloxacin whereas less sensitive to ofloxacin. For therapeutic management of bacterial infection (conjunctivitis and keratitis) of eye, 36 dogs were randomly divided into 2 groups, Group I and Group II. In group I, ciprofloxacin was found effective on 14th day post-treatment in subgroup A and C dogs and in group II, gentamicin was found effective on 14th day post-treatment in subgroup D and F dogs.EnglishThesis
