Resumo
Background: Ocular biometrics is an easy to perform, safe, non-invasive and low-cost exam that provides immediate resultswith excellent definition. Brachycephalic dogs have a high risk of developing eye problems, and the early appearance isfrequent due to factors linked to anatomical conformation. The aim of the present study was to perform eye biometrics inFrench Bulldog dogs through ultrasound, correlating with body and head size.Materials, Methods & Results: Clinical examination, ophthalmic examination and ocular biometrics were performed usingB-mode ultrasonography, using a 10 megahertz frequency transducer in 30 French Bulldog dogs, aged 1-6 years old, maleand females from the Br Lords Staff kennel and the Radiovet - Rio de Janeiro veterinary clinic. A drop of anesthetic eyedrops containing 1% tetracaine hydrochloride and 0.1% phenylephrine hydrochloride was instilled and the direct contacttechnique was performed with the cornea with the help of sterile water-soluble lubricating acoustic gel between the transducerand the examined eye. These measurements were correlated with cephalic measurements (frontal-occipital distance, skullcircumference, distance between the zygomatic arches and frontal-nasal distance) and with body measurements (lengthof the dog from the cranial end of the sternum to the ischial tuberosity and height of the withers from the cranial angleof the scapula to the ground). No chemical restraint was necessary. Dogs were positioned seated or in sternal decubitus,with slight physical restraint. All measurements were performed by the same examiner. There was no significant difference between the parameters of male and female eye biometrics and there was no difference between the measurementsof the right and left eyes. The mean value of axial bulb length was 19.51 ± 0.58 mm, for the thickness of the lens, 6.71 ±0.66 mm, for depth of the anterior chamber, 2.36 ± 0.89 mm and for the depth of the vitreous chamber...
