本文应用 Wissely 氏角膜计,测量了正常的1岁以下婴儿共254例,508只眼,并测量了了正常成人109例218只眼作对照。测量结果发现:新生儿角膜横径平均值为9.96±0.11毫米,角膜垂直径平均值为9.47±0.33毫米:半岁婴儿角膜横径平均值为10.62±0.23毫米,角膜垂直径平均值为10.12±0.21毫米;1周岁婴儿角膜横经平均值为10.94±0.22毫米、角膜垂直径平均值为10.42±0.19毫米:成年人角膜横径平均值为11.67±0.31毫米,角膜垂直径平均值为10.97±0.33毫米。从测量结果中,了解到初生后角膜尚有一段时间的生长发育过程,其生长主要是半岁以内。一周岁末要儿角膜横径及垂直径大小均未达到成年人的水平。经统计学处理,两者有显著差异(P<0.01)。测量一岁以内婴儿角膜不同时期的直径大小,不仅了解其生长发育情况,而且对婴(幼)儿型先天性青光眼的诊断有重要帮助。
In this paper, Wissely’s cornea was used to measure the normal infants under the age of 1 year, a total of 254 cases, 508 eyes, and measures the normal adult 109 cases of 218 eyes as a control. Measurement results showed that: the average neonatal corneal diameter was 9.96 ± 0.11 mm, the average diameter of the cornea was 9.47 ± 0.33 mm: half-year-old baby corneal diameter average of 10.62 ± 0.23 mm, corneal vertical diameter average of 10.12 ± 0.21 mm; 1-year-old baby corneal transverse mean 10.94 ± 0.22 mm, corneal vertical diameter average of 10.42 ± 0.19 mm: the average adult corneal diameter 11.67 ± 0.31 mm, the average vertical corneal diameter of 10.97 ± 0.33 Mm. From the measurement results, we know that the cornea still has a period of growth and development after birth, its growth is mainly within six months of age. Corneal diameter and vertical diameter at the end of one year did not reach the level of adults. After statistical analysis, there was a significant difference (P <0.01). Measuring the diameter of baby corneas at different ages within one year of age, not only to understand their growth and development, but also for infant (juvenile) children with congenital glaucoma diagnosis is important help.
