Abstract

Objective: To establish the central corneal thickness (CCT) and intraocular pressure (IOP) of normal Holstein cattle and any relationship with age.

Methods: Age of 50 Holstein cattle was recorded in days. CCT was measured by ultrasonic pachymetry, and IOP values were recorded by rebound tonometry from a total of 100 eyes. CCT and IOP values were subsequently analyzed in relation to age. The animals were divided into the following two groups: calves (< 360 days old) and adults (≥ 360 days old).

Results: Mean CCT value of all animals was 723.1 ± 75.9 μm in the right eye, 714.5 ± 82.2 μm in the left eye. Mean IOP value of 100 eyes was 25.4 ± 8.07 mm/Hg in the right eye, 24 ± 7.89 mm/Hg in the left eye. Mean CCT and IOP values of the animals < 360 days old were 697.7 ± 8.28 μm and 21.6 ± 0.77 mm/Hg respectively. Mean CCT and IOP values of the animals ≥ 360 days old were 768.1 ± 14.4 μm and 31.9 ± 1.18 mm/Hg, respectively. A statistically significant difference was observed between the groups in terms of CCT and IOP values (p < 0.001). A positive correlation was identified between CCT and age (r = 0.57, p < 0.001) and between IOP and age (r = 0.488, p < 0.001).

Conclusions: This study documents the age-related increase in both CCT and IOP values in cattle.

正常荷斯坦牛角膜中央厚度和眼压随年龄增长而增加。

目的：探讨正常荷斯坦牛角膜中央厚度（CCT）、眼压（IOP）与年龄的关系。方法：记录50头荷斯坦牛的日龄。超声测厚法测量CCT，回弹眼压法记录100只眼的IOP值。随后分析CCT和IOP值与年龄的关系。试验动物分为犊牛（< 360日龄）和成牛（≥360日龄）两组。结果：各动物右眼CCT平均值为723.1±75.9 μm，左眼为714.5±82.2 μm。100眼平均IOP值右眼25.4±8.07 mm/Hg，左眼24±7.89 mm/Hg。< 360日龄的小鼠CCT平均值为697.7±8.28 μm， IOP平均值为21.6±0.77 mm/Hg。≥360日龄小鼠CCT平均值为768.1±14.4 μm， IOP平均值为31.9±1.18 mm/Hg。在CCT和IOP值方面，两组之间的差异具有统计学意义(p)。结论：本研究记录了牛CCT和IOP值的年龄相关增加。
