The corneal diameter was recorded and the ocular axial length measured by A-scan ultrasonography in 31 eyes of 17 children (ages 0.05 to 7.0 years) who had undergone or were about to undergo surgery for primary congenital glaucoma. These measurements were also done in 60 normal eyes of 33 children (ages 0.20 to 9.6 years) undergoing nonophthalmic surgery. Both measures were usually greater than normal in the glaucomatous eyes. However, the corneal diameter was more sensitive than the axial length in identifying congenital glaucoma. The axial length measurement did not provide additional useful information for any of the eyes. We conclude that the corneal diameter is a more reliable guide than the axial length in the assessment of congenital glaucoma. A transparent plastic gauge for rapid and accurate measurement of the corneal diameter is described.
对17名儿童（年龄0.05至7.0岁）的31只眼睛进行了角膜直径记录，并通过A超超声测量眼轴长度，这些儿童已经接受或即将接受原发性先天性青光眼手术。对33名接受非眼科手术的儿童（年龄0.20至9.6岁）的60只正常眼睛也进行了这些测量。青光眼患者的这两项测量结果通常都高于正常水平。然而，在识别先天性青光眼方面，角膜直径比眼轴长度更敏感。眼轴长度测量对任何眼睛都没有提供额外有用的信息。我们得出结论，在评估先天性青光眼时，角膜直径比眼轴长度是更可靠的指标。本文描述了一种用于快速准确测量角膜直径的透明塑料测量仪。
