| Abstract: | The normal ultrasonographic anatomy and biometry of 60 adult sheep and 60 adult cattle eyes were evaluated by saline immersion technique. Five intraocular dimensions were taken: corneal thickness, aqueous chamber depth, lens diameter, vitreous chamber depth and axis bulbi. The eyes were then frozen and cut in a sagittal plane and the same dimensions were measured directly. A- and B-mode measurements were compared with each other and with that of direct measurements. There was no difference between A- and B-mode measurements. However, there was a difference between ultrasound and direct measurements. |
