Abstract：
A complete ophthalmological examination, including basic diagnostic tests such as the Schirmer tear test (STT) and intraocular pressure (IOP) measurement performed by tonometry in particular species and breeds, is essential for obtaining a clear diagnostic result and avoiding diagnostic misinterpretations. STT and IOP values have been poorly described for sheep. Therefore, this study aimed to determine the normal range for STT and tonometry values in clinically normal Latvian Darkhead lambs and ewes. Both eyes of 100 sheep (200 eyes)-50 lambs (1-3 months old) and 50 ewes (1-8 years old)-underwent complete ophthalmic examinations, including STT and IOP evaluation. The mean ± standard deviation of STT values for both eyes in lambs and ewes were 13.12 ± 3.91 mm/min and 13.68 ± 4.09 mm/min, respectively. The IOP in lambs and ewes was 14.04 ± 3.68 mmHg and 19.16 ± 3.24 mmHg, respectively. Furthermore, the suggested reference range for the STT was 12.00-14.23 mm/min in lambs and 12.52-14.84 mm/min in ewes, while the reference IOP range was determined to be 13.00-15.08 mmHg in lambs and 18.24-20.08 mmHg in ewes. No statistically significant differences in STT and IOP values were observed for both eyes. However, the IOP value for both eyes was statistically significantly higher in ewes compared to lambs (p < 0.01). This study provides reference values for the STT and IOP in healthy Latvian Darkhead lambs and ewes.
摘要：
完整的眼科检查，包括基本的诊断测试，如Schirmer撕裂试验（STT）和眼压测量（IOP）在特定物种和品种，对于获得明确的诊断结果和避免诊断误解至关重要。绵羊的STT和IOP值描述不佳。因此,本研究旨在确定临床上正常的拉脱维亚黑头羔羊和母羊的STT和眼压值的正常范围。100只绵羊（200眼）-50只羔羊（1-3个月大）和50只母羊（1-8岁）的双眼-接受了完整的眼科检查，包括STT和IOP评估。羔羊和母羊双眼STT值的平均值±标准偏差分别为13.12±3.91mm/min和13.68±4.09mm/min,分别。羔羊和母羊眼压分别为14.04±3.68mmHg和19.16±3.24mmHg,分别。此外，建议的STT参考范围在羔羊中为12.00-14.23mm/min，在母羊中为12.52-14.84mm/min，而羔羊的参考眼压范围为13.00-15.08mmHg，母羊为18.24-20.08mmHg。两只眼睛的STT和IOP值没有观察到统计学上的显着差异。然而,与羔羊相比，母羊的双眼IOP值具有统计学意义（p<0.01）。这项研究为健康拉脱维亚黑头羔羊和母羊的STT和IOP提供了参考值。
