Ultrasonographic Measurements of Intraocular Structures in Healthy Najdi Goat

The aim of this study was to determine intraocular anatomical parameters of the Najdi goat in normal state using ultrasonographic images. Since intra ocular parameters undergo changes by inflammation induced by different eye diseases, Knowledge of the dimensions of ocular components and their normal range is essential for better understanding of clinical vision disorders. Ocular echobiometric inspection was carried out on ۱۲-۱۸ months old healthy Najdi breed goats. Ultrasonographic images were obtained by a ۱۰MHz linear probe in the sagittal plane. The ocular echobiometric measurement revealed the following: axial globe length (AGL) ۱۹.۸±۰.۳mm, anterior chamber depth (ACD) ۱.۸۲±۰.۱۶mm, vitreous chamber depth (VCD) ۹.۴۵±۰.۱۵mm, sclera retinal rim thickness (SRT) ۱.۲۵±۰.۰۷mm, lens thickness (LT) ۷.۴۵±۰.۲۵mm and corneal thickness (CT) ۰.۴۵±۰.۰۱mm. The estimated dimensions of the normal ocular components obtained in this study are presented in a table to be used by veterinarians in the diagnosis of goat ocular diseases.
