2.1. Study Area and Duration The Teaching Veterinary Hospital (TVH) of Chittagong Veterinary and Animal Sciences University (CVASU) is the only seat of clinical learning of veterinary practices under the close supervision of the concerned teaching staff members of the clinical departments in Bangladesh. It is a busy clinic providing veterinary services for the farm and companion animals, horses, poultry etc. Most of the diseased and sick animals from different areas of Chittagong are brought to TVH for better treatment. Majority of patients are a goat. Due to more patient concentration and better opportunity to handle, the study was undertaken at TVH, CVASU. The study was performed from January to December 2017.
2.2. Study Population The cases of IKC were identified by observing the clinical sign of eye lesions like reddening and swelling, watery or mucopurulent discharge, lacrimation, corneal opacity, photophobia and loss of vision. We considered some selective variables like age, breed, sex, body color, illness duration, housing condition, previous treatment, eye involvement, treatment duration, treatment response, lacrimation, concurrent disease, body temperature and location of the patient to identify the risk factors. We found 29 goats clinically infected with the IKC admitted at TVH of CVASU during this study period.
2.3. Data Collection We prepared a questionnaire to collect patients’ information. When the patients brought to the ‘TVH, registration was completed by recording owners name and address. Then the questionnaire was filled up by faceto-face interview with the goat owners and close examination of the patient.
2.4. Treatment Trial and Follow Up After diagnosis, all IKC infected goat patients were treated with intramuscular injection of long-acting oxytetracycline (Renamycin LA®, 20%, Renata limited, Bangladesh) at the dose of 20 mg/kg body weight and subconjunctival injection of dexamethasone (Dexaroid®, 2%, Eskayef limited, Bangladesh) at the dose of 0.5 mg/eye at alternate days for 5 to 7 dose. Autohemotherapy was also administered at a dose of 3-5 ml/animal based on the body size at 5 days interval for 3 to 5 dose. Response to treatment was recorded by contact over a phone call with the owners. In some cases directly visiting the owner’s home or when the patients again brought to the hospital.
2.5. Statistical Analysis All data was input in Microsoft Office Excel Worksheet Program and were analyzed using STATA/IC-11.0. Significant differences among the variables were calculated using Pearson’s Chi-square test. The p-value less than 0.05 were considered as significant.
