The capillaries of overacting inferior oblique muscles from children with strabismus and of dog inferior oblique muscles were ultrastructurally described. Biopsy material was used in all instances. The mean diameter of the capillary lumen was 2.03 microns for the human inferior oblique and 2.76 microns for the dog inferior oblique. Quantitative estimates of capillary basement membrane width were obtained by two different methods of measurement. The capillaries of human and dog inferior oblique muscles were compared with capillaries of human gastrocnemius muscle and of dog quadriceps muscle. The data were statistically evaluated. It was found that the mean basement membrane width of capillaries of overacting inferior oblique muscles is quite similar to that of the dog normal inferior oblique muscles, showing 2,049 A in overacting muscles and 1,976 A in normal muscles. With both methods of measurement, the mean basement membrane width of inferior oblique muscles appeared thicker than the mean basement membrane of capillaries of the leg muscles in man and in dog as well. It is suggested that the thickening of the capillary basement membrane of inferior oblique muscles represents a regional characteristic. Marked variation in the thickness of the basement membrane was encountered in all muscles.
对斜视患儿的亢进性下斜肌以及犬的下斜肌的毛细血管进行了超微结构描述。所有病例均采用活检材料。人类下斜肌毛细血管腔的平均直径为2.03微米，犬下斜肌为2.76微米。通过两种不同的测量方法对毛细血管基底膜宽度进行了定量估计。将人类和犬的下斜肌毛细血管与人类腓肠肌和犬股四头肌的毛细血管进行了比较。对数据进行了统计学评估。结果发现，亢进性下斜肌毛细血管的平均基底膜宽度与犬正常下斜肌的相当相似，亢进性肌肉中为2049埃，正常肌肉中为1976埃。采用两种测量方法时，人类和犬的下斜肌毛细血管平均基底膜宽度似乎也比腿部肌肉毛细血管的平均基底膜厚。提示下斜肌毛细血管基底膜增厚代表一种区域特征。在所有肌肉中均发现基底膜厚度存在明显差异。
