The iridocorneal angle of the left eye was investigated in 203 Samoyeds. Comparison was made of judgements of the width of the anterior opening of the ciliary cleft when performing gonioscopy with an objective method of estimation based on measurements on goniophotographs. Results indicated high degree of correlation. Various degrees of narrowness of the iridocorneal angle width were revealed and clinical glaucoma with total-angle closure was found in 6 of 203 dogs. The intraocular pressure was significantly (P less than 0.01) higher in eyes with closed iridocorneal angles than in eyes with any other width of the angle. Appearance of the structures of the iridocorneal angle, particularly the pigment bands, indicated extensive individual variation. In approximately 25% of the eyes, dysplasia of the pectinate ligaments of variable degree existed, indicating that this anomaly is common in the Samoyed breed. Significant difference was not evident in intraocular pressure in eyes with different degrees of dysplasia of the pectinate ligaments.
对203只萨摩耶犬的左眼虹膜角膜角进行了研究。在进行前房角镜检查时，将睫状裂前开口宽度的判断结果与基于前房角照片测量的客观估计方法进行了比较。结果表明两者具有高度相关性。发现了不同程度的虹膜角膜角宽度变窄情况，在203只犬中有6只出现了全角闭合型临床青光眼。虹膜角膜角闭合的眼睛眼压显著（P<0.01）高于其他角度宽度的眼睛。虹膜角膜角结构的外观，尤其是色素带，显示出广泛的个体差异。在大约25%的眼睛中，存在不同程度的梳状韧带发育异常，表明这种异常在萨摩耶犬种中很常见。梳状韧带不同程度发育异常的眼睛眼压无明显差异。
