The purpose of this study was to describe the normal ocular anatomy and establish reference values for ophthalmic tests in the Barbary sheep or aoudad (Ammotragus lervia). Aoudad eyes are large and laterally positioned in the head with several specialized anatomic features attributed to evolutionary adaptations for grazing. Normal values for commonly used ophthalmic tests were established, Schirmer tear test (STT) - 27.22 ± 3.6 mm/min; Predominant ocular surface bacterial microbiota - Staphylococcus sp.; Corneal esthesiometry- 1.3 ± 0.4 cm; Intraocular pressure by rebound tonometry- 19.47 ± 3.9 mmHg; Corneal thickness- 630.07 ± 20.67 µm, B-mode ultrasonography of the globe-axial eye globe length 29.94 ± 0.96 mm, anterior chamber depth 5.03 ± 0.17 mm, lens thickness 9.4 ± 0.33 mm, vitreous chamber depth 14.1 ± 0.53 mm; Corneal diameter-horizontal corneal diameter 25.05 ± 2.18 mm, vertical corneal diameter 17.95 ± 1.68 mm; Horizontal palpebral fissure length- 34.8 ± 3.12 mm. Knowledge of these normal anatomic variations, biometric findings and normal parameters for ocular diagnostic tests may assist veterinary ophthalmologists in the diagnosis of ocular diseases in this and other similar species.
本研究的目的是描述巴巴里绵羊或旋角大羚羊（Ammotragus lervia）的正常眼部解剖结构，并建立其眼科检查的参考值。旋角大羚羊的眼睛较大，位于头部两侧，具有一些特殊的解剖特征，这些特征归因于其为适应放牧而进行的进化。建立了常用眼科检查的正常值，泪液分泌试验（STT）-27.22±3.6毫米/分钟；主要眼表细菌微生物群-葡萄球菌属；角膜感觉测量-1.3±0.4厘米；回弹眼压计测量的眼压-19.47±3.9毫米汞柱；角膜厚度-630.07±20.67微米，眼球B型超声检查-眼轴长度29.94±0.96毫米，前房深度5.03±0.17毫米，晶状体厚度9.4±0.33毫米，玻璃体腔深度14.1±0.53毫米；角膜直径-水平角膜直径25.05±2.18毫米，垂直角膜直径17.95±1.68毫米；睑裂水平长度-34.8±3.12毫米。了解这些正常的解剖变异、生物测量结果和眼部诊断检查的正常参数，可能有助于兽医眼科医生诊断该物种及其他类似物种的眼部疾病。
