Abstract

Objective: To assess intraocular pressure (IOP) development in cranes and determine the impact of age, weight, species, head position, and sex.

Animals studied: Whooping cranes (WC) (Grus americana), and Mississippi-sandhill cranes (MSC) (Grus canadensis pulla).

Procedures: Chicks were manually restrained on days 1-3, 7, 21, 35, 60, 75, and 120 for routine examinations. IOP was opportunistically measured utilizing the Tonovet Plus® in D setting with the head above the heart (AH) and below the heart (BH). Values were also obtained longitudinally in adults (>120 days old) upon presentation in 1 year.

Results: Intraocular pressure was highly correlated with age and weight in chicks. For every kilogram gained, IOP increased 2.46 ± 0.08 mmHg in WC and 2.66 ± 0.11 mmHg in MSC. Once hatched, IOP increased 1.13 ± 0.04 mmHg in WC and 0.87 ± 0.04 mmHg in MSC every 10 days. IOP was similar to adults at 120 days of age. In adult WC, mean IOP AH was 24.0 ± 0.4 mmHg, and BH was 27.9 ± 0.4 mmHg, there was a significant difference regarding head positioning and sex, females (25.3 ± 0.4 mm Hg) had lower IOP than males (26.5 ± 0.4 mmHg). In adult MSC, mean IOP AH was 20.7 ± 0.4 mmHg, and BH was 24.6 ± 0.4 mmHg. The difference between head positioning was significant.

Conclusions: This study documents the correlation between IOP and weight or age during early development in cranes, as well as the importance of head positioning.

百灵鹤（Grus americana）和密西西比-沙丘鹤（Grus canadensis pulla）的纵向眼压测量。

目的：评估鹤的眼压发育情况，并确定其对年龄、体重、物种、头部位置和性别的影响：评估鹤的眼内压（IOP）发育情况，并确定年龄、体重、物种、头部位置和性别的影响：百灵鹤（WC）（Grus americana）和密西西比沙丘鹤（MSC）（Grus canadensis pulla）：雏鸟在第 1-3、7、21、35、60、75 和 120 天被人工束缚，进行常规检查。在头部高于心脏（AH）和低于心脏（BH）的情况下，使用 Tonovet Plus® D 档测量眼压。此外，还纵向测量了成人（大于 120 天）1 年后的眼压值：结果：小鸡的眼压与年龄和体重高度相关。体重每增加一公斤，WC 和 MSC 的眼压分别增加 2.46 ± 0.08 mmHg 和 2.66 ± 0.11 mmHg。孵化后，每隔 10 天，WC 和 MSC 的眼压分别增加 1.13 ± 0.04 mmHg 和 0.87 ± 0.04 mmHg。120日龄时的眼压与成人相似。成年WC的平均眼压AH为24.0 ± 0.4 mmHg，BH为27.9 ± 0.4 mmHg，头部位置和性别有显著差异，女性（25.3 ± 0.4 mmHg）的眼压低于男性（26.5 ± 0.4 mmHg）。成人间充质干细胞的平均眼压 AH 为 20.7 ± 0.4 mmHg，BH 为 24.6 ± 0.4 mmHg。头部定位之间的差异显著：本研究记录了鹤早期发育过程中眼压与体重或年龄的相关性，以及头部位置的重要性。
