    (CSKHPKV, Palampur, 2018-07-16) CAMARA, ADRIAN ACACIO; Tyagi, S.P.
    The present study was carried out to standardize fundus imaging in dogs, evaluate the diagnostic and therapeutic management of various ocular affections in dogs and to 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, 2017 to March, 2018. The techniques of fundus examination and photography using different equipment were standardized in dogs. Different variables such as illumination level, examination distance, aperture size, field of view, magnification and dioptric settings were studied and the best combinations were recorded. Various restraining positions of dogs to facilitate fundus imaging were evaluated and compared. The ophthalmoscopic and ultrasonographic appearance of the normal canine fundus was standardized. It was observed that the fundic field of view was largest with the Indirect ophthalmoscope and smallest with Direct, whereas the magnification was in a reverse order. Fundus photography using panoptic ophthalmoscope and ‘iExaminer’ mount for a smartphone provided quality images consistently. A thorough fundus examination could be performed in dogs restrained in the standing and sitting position. Yellow-green was the most common colour of the tapetal area of the fundus, while it was dark brown for the non-tapetal area. Polygonal shaped optic disc was seen in most dogs and the most common colour of the disc was pink. The overall prevalence of ocular affections in animals was 12.99 per cent. Sex-wise prevalence was higher in males. Species-wise prevalence was highest in dogs.
