Ocular ultrasonography is seldom performed in cattle. Here, we compared three ultrasound probes (linear, convex, transrectal gynecological) for the measurement of eight eye biometry parameters on vertical and horizontal scans. The sample population was 20 healthy calves (n = 10 Holstein, n = 10 Piedmontese breed). Intragroup (same probe for vertical vs. horizontal scanning) and intergroup (different probes measuring the same biometric parameter) comparisons were performed using Student's -test and the Mann-Whitney test. Statistical significance was set at ≤ 0.05. Intragroup comparison revealed few significant differences. Ultrasound examination with the convex transducer detected more differences than either of the two other probes on vertical (linear six out of eight; transrectal gynecological four out of eight) and horizontal (linear six out of eight; transrectal gynecological six out of eight) scans. Similar results were obtained for both breeds. More non-valuable parameters on the horizontal (77 out of 320, 24%) and the vertical (85 out of 320, 26%) ( ≤ 0.001) scans were obtained with the convex transducer. Both linear transducers were found comparable for ocular ultrasonography in field conditions. However, given its widespread application in the field, the transrectal gynecological transducer may offer veterinarians the added advantage of familiarity and ease-of-use without any additional costs.
牛很少进行眼部超声检查。在此，我们比较了三种超声探头（线性、凸阵、经直肠妇科探头）在垂直和水平扫描时对八项眼部生物测量参数的测量情况。样本群体为20头健康犊牛（n = 10头荷斯坦牛，n = 10头皮埃蒙特牛）。使用学生t检验和曼 - 惠特尼检验进行组内（垂直扫描与水平扫描使用相同探头）和组间（测量相同生物测量参数的不同探头）比较。统计学显著性设定为P≤0.05。组内比较显示差异不显著。在垂直扫描（线性探头8项中有6项；经直肠妇科探头8项中有4项）和水平扫描（线性探头8项中有6项；经直肠妇科探头8项中有6项）时，凸阵探头检测到的差异比其他两种探头更多。两个品种均得到类似结果。使用凸阵探头在水平扫描（320项中有77项，24%）和垂直扫描（320项中有85项，26%）（P≤0.001）中获得的无价值参数更多。在现场条件下，发现两种线性探头在眼部超声检查方面相当。然而，鉴于经直肠妇科探头在该领域的广泛应用，它可能为兽医提供熟悉且易用的额外优势，且无需任何额外成本。
