Abstract :

The purpose of this study was to determine the anatomical parameters of the eyeball in a normal state in the Kurdish sheep using ultrasonographic images in order to find out the clinical aspect of the ocular structures and the normal range of ocular parameters using the ultrasonographic machine. Ocular echo-biometric inspections were carried out on sheep (16-24 months old) from the Kurdish breed. Ultrasonographic images were obtained with an 8-12 MHz linear probe in the sagittal plane. Based on the results of the present study, axial globe length (AGL) (24.3±0.3), anterior chamber depth (ACD) (3.1±0.16), vitreous chamber depth (VCD) (11.30±0.15), sclera retinal rim thickness (SRT) (1.70±0.06), lens thickness (LT) (9.65±0.25) and corneal thickness (CT) (0.875±0.03) were reported. The different dimensions of the natural eyeball components obtained in normal and healthy conditions were presented so that veterinarians in different eye diseases can compare the size of the internal structures of the patient's eyeball with the size of the structures in normal and healthy conditions.
