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.
