Biometria ocular e sua relação com tamanho corporal e da cabeça em cães da raça buldogue francês

Abstract

The popularity of the French Bulldog breed as a companion animal has shown significant growth in recent years and, therefore, it is important to know and standardize the parameters of ocular biometrics for this breed. The skull of dogs varies in shape and size according to the individual's breed or conformation. The knowledge of ocular biometrics is extremely important for the understanding and early diagnosis of some anomalies related to the growth of ocular structures. The aim of the present work is to perform eye biometrics in French Bulldog dogs by means of ultrasound, correlating with the body and head size of French Bulldog dogs. Thirty healthy French Bulldog between one and six years old were included. Ocular biometrics were performed using B-mode ultrasound using the technique of direct contact with the cornea, and then these measurements were correlated with cephalic measurements (frontal-occipital distance, skull circunference, distance between the zygomatic arches and distance fronto-nasal) and body measurements (length of the dog from the tip of the sternum to the tip of the ischium and the height of the withers from the cranial angle of the scapula to the ground). There was no significant difference between the parameters of male and female eye biometrics and there was no difference between the measurements of the right and left eyes. The mean value of the axial length of the bulb was 19.51 ± 0.58 mm, for the thickness of the lens, 6.71 ± 0.66 mm, for the depth of the anterior chamber, 2.36 ± 0.89 mm and for the depth of the glass chamber, 10.44 ± 1.32 mm. There was no relationship between the measurements of ocular biometrics and the measures of height, length and size of the skull.
