【摘要】：目的：分析青少年屈光状态与其屈光要素,了解屈光要素对青少年近视形成的可能影响,以期根据屈光要素对青少年的屈光状态进行预测。方法： 1研究对象：2010年3月-2011年1月于湖南省人民医院眼视光中心门诊收集的屈光不正病例数726人(1452只眼)。其中男性380人,女性346人,年龄4到18岁,平均年龄10.37±2.92岁,均排除器质性病变,眼球发育正常,未接受过内眼和外眼手术治疗。 2检查方法：检测基本生长发育情况,身高(H)cm，体重(W)kg.测量角膜厚度、前房深度(ACD)、最小角膜屈光力(K1)和最大角膜屈光力(K2)、玻璃体腔长度(VL)、晶状体厚度(LT)、眼轴长度(AL)、屈光状态、裸眼视力、矫正视力等。 3分组统计：分别按屈光度、眼轴长度、年龄分组,采用单因素方差分析,对于分析有意义的才用SNK法进行Q检验。左右两眼比较采用配对t检验,性别间比较采用成组t检验,并对结果进行分析。分析眼屈光要素的差别以及屈光要素间的相互关系,并用多元线性回归分析建立眼轴长度、相关屈光要素和生长发育因素间关系的回归方程。P0.05被认为具有统计学意义。结果： 1在4-6岁组中,屈光度与AL、VL相关,屈光度与其它屈光要素无相关。AL与VL有相关性。K1与K2有相关性。高度近视眼组与其它组别之间的AL值差异有显著性(p0.05),而远视眼组和正视眼组以及低度近视眼组的AL值差异无显著性。 2在7-12岁组中,AL与K1、K2之间均存在负相关关系,AL与ACD之间存在正相关关系。最小角膜曲率与最大角膜曲率均高度正相关,即K1与K2之间呈正相关。 3在13-18岁组中,屈光度与AL、VL相关,屈光度与其它屈光要素无相关。AL与VL、ACD有相关性。低度远视眼与高度远视眼以及高度近视眼组的AL值差异有显著性(p0.05),中度远视眼组与低、中高度近视眼组的AL值差异有显著性(p0.05)。高度远视眼组与低度远视眼、正视眼以及低、中高度近视眼组的AL值差异有显著性(p0.05)。 44～12岁组的男生的AL、VL与身高、体重的发育是正相关关系。4～12岁组的女生的AL.VL与身高、体重正相关。4～6岁组的男女AL以及其他屈光要素的生长发育基本一致。7～12岁组的男性的AL的发育显著快于女性,而男性的角膜曲率值(K1、K2)则明显比女性要小。13～18岁组中,男女性的则无差异。 5利用多元逐步回归分析得到AL.ACD.LT.VL.身高和屈光度有关的预测方程：Y=0.994+0.942X1+0.917X2+0.973X3-0.016X4+0.231X5+0.221X6(Y表示AL,X1表示VL,X2表示LT，，X3表示ACD.X4表示屈光度,X5表示身高,X6表示年龄,VL的标准化回归系数为0.909,ACD的标准化回归系数为0.168,LT的标准化回归系数为0.233) 结论：屈光状态与屈光要素间的匹配密切相关,4～18岁儿童的眼轴(AL)可以根据玻璃体腔长度(VL)、晶状体厚度(LT)以及前房深度(ACD)、身高和屈光度进行预测。
[Abstract]:Objective: to analyze the diopter state and its refractive factors in adolescents, and to understand the possible effects of refractive factors on the formation of juvenile myopia, in order to predict the refractive state of adolescents according to the refractive factors. Methods: 1 subjects: from March 2010 to January 2011, 726 cases (1452 eyes) of ametropia were collected in the clinic of the Eye Optometry Center of Hunan Provincial people's Hospital. There were 380 males and 346 females, aged from 4 to 18 years, with an average age of 10.37 卤2.92 years. Height (H) cm, weight (W) kg. Corneal thickness, anterior chamber depth (ACD), minimum corneal refractive power (K1) and maximum corneal refractive power (K2), vitreous length (VL), lens thickness (LT), axial length (AL), refractive state, naked vision were measured. The corrected visual acuity was divided into three groups: diopter, axial length, age, single factor ANOVA, and SNK method for the analysis. Paired t test was used to compare left and right eyes, and group t test was used to compare sex. The results were analyzed. The difference of refractive factors and the relationship between refractive factors were analyzed. The regression equation of the relationship between refractive factors and growth and development factors was established by multiple linear regression analysis. P05 was considered to have statistical significance. Results: 1in the 4-6 years old group, the diopter was correlated with ALV, and the diopter was not correlated with other refractive elements. All was correlated with VL. K1 was correlated with K2. There was significant difference in AL between high myopia group and other groups (p0.05), but there was no significant difference in AL value between hyperopia group and orthopia group and low myopia group. There is a positive correlation between AL and ACD. The minimum corneal curvature was positively correlated with the maximum corneal curvature, that is, K1 was positively correlated with K2. 3 in 13-18 years old group, the diopter was correlated with ALVL, but the diopter was not correlated with other refractive factors. AL was correlated with VLACD. There was significant difference in AL value between low hyperopia group and high myopia group (p0.05), and significant difference between moderate hyperopia group and low and middle high myopia group (p0.05). There was significant difference in AL value between high hyperopia group and low hyperopia group, right vision group and middle and high myopia group (p0.05). The development of weight was positively correlated with the AL.VL of the girls in the age group of 12 years old. The development of AL was significantly faster in the male group than in the female group, and the growth and development of the male and female AL and other refractive factors were basically the same in the age group of 6 years old and the age group of 6 years of age. However, the corneal curvature value (K _ 1K _ 2) of male was significantly smaller than that of female (n = 18), and there was no difference between male and female. 5 the AL.ACD. LT.VL was obtained by multivariate stepwise regression analysis. The prediction equation related to height and diopter: yun0.994 0.942X1 0.917X2 0.973X3-0.016X4 0.231X5 0.221X6 The quasi-regression coefficient is 0.233) conclusion: the matching between refractive state and refractive factors is closely related to the ocular axis (AL) of children aged 418 years old, depending on the length of vitreous cavity (VL), lens thickness (LT) and anterior chamber depth. (ACD), height and diopter were predicted.
