摘　　要：目的探讨小学生和中学生在调节和非调节状态下眼前节部分解剖结构的动态变化规律。方法横断面研究。采用超生生物显微镜（UBM）检测福州市54例小学生及55例中学生在调节和非调节状态下的睫状体、虹膜及房角等位置相关数据，数据采用配对t检验和独立样本t检验进行分析。结果非调节状态下小学生组各指标数值如下：睫状突长度（CPD）值（160．53±17．78）um，睫状突宽度（CT）值（90.01±34．30）um，虹膜睫状体距离（ICPD）值（23．11±3．33）um，虹膜厚度（IT）1值（35．95±6．60）um，IT2值（52．81±9．94）um，小梁睫状体距离（TCPD）值（151．27±23．11）um，巩膜外侧面与虹膜长轴的夹角θ3值（39．23±7．46）。虹膜外侧面与睫状突的夹角04值（56．02±6．75）.；调节状态下相应指标分别为：（187．62±15．44）um、（74．23±19．87）um、（19．78±2．69）um、（30．34±5．83）um、（47．11±6．71）um、（131．55±20．02）um、（31．68±5．14）。、（50．39±4．89）。。调节与非调节状态下比较，差异均有统计学意义（t=8．45、2．93、5．72、4．68、3．49、4．74、6．12、4．96，P〈0．05）。中学生组非调节状态下以上各指标分别为：（214．64±15．25）um、（99．13±17．80）um、（27．92±9．00）um、（40．72±6．43）um、（56．57±9．13）pm、（176．82±28．06）um、（43．73±6．93）、（60．15±10．48）°；调节状态下分别为：（271．38±11．96）um、（93．27±10．42）um、（21．66±7．54）um、（35．68±4．37）um、（50．17±6．49）um、（136．41±19．35）um、（39．51±5．28）°、（53．68±9．12）°。调节与非调节状态下各参数比较，差异均有统计学意义（t=20，91、2．03、3．81、4．63、4．08、8．47、3．46、3．33，P〈0．05）。同样在调节状态下，小学生组和中学生组所有睫状体相关指标之间差�Objective To investigate the dynamic changes in the anatomy of the anterior segment with and without accommodation in primary and middle-school students. Methods This was a cross-sectional study. Ultrasound biomocroscopy （UBM） was used to test 54 primary students and 55 middle-school students in Fuzhou. Some parameters related to the ciliary body, iris, anterior chamber angle and other relevant data were measured with UBM. Data were analyzed using a paired t test and independent-samples t test. Results Results for the primary student group without accommodation were as follows： the ciliary process distance （CPD） was （160.53±17.78）um,ciliary body thickness （CT） was （90.01±34.30）um, iris-ciliary process distance （1CPD） was （23.11±3.33）um,iris thickness （IT） 1 was（35.95±6.60）um,and IT2 was （52.81±9.94）um, trabecular ciliary process distance （TCPD） was （151.27±23.11）um,θ3 was （39.23±7.46） ° and 04 was （56.02±6.75）The results with accommodation were as follows： （187.62±15.44）um、（74.23±19.87）um、（19.78±2.69）um、（30.34±5.83）um、（47.11±6.71）um、（131.55±20.02）um、（31.68±5.14）.、（50.39±4.89）.（t=8.45,2.93,5372,4.68,3.49,4.74,6.12,4.96,P〈0.05.The respective results for the middle-school student group without accommodation were as follows： （214.64±15.25）um、（99.13±17.80）um、（27.92±9.00）um、（40.72±6.43）um、（56.57±9.13）pm、（176.82±28.06）um、（43.73±6.93）、（60.15±10.48）°; Results with accommodation were as follows：（271.38±11.96）um、（93.27±10.42）um、（21.66±7.54）um、（35.68±4.37）um、（50.17±6.49）um、（136.41±19.35）um、（39.51±5.28）°、and（53.68±9.12）°.（t=20.91, 2.03, 3.81, 4.63, 4.08, 8.47, 3.46, 3.33, P〈0.05）. There was a significant differe,lce between these 2 groups with accommodation （in the same sequence, t=30.95, 6.10, 4.47, 5.29, 2.37, 7.70, 2.32, and 6.98, P〈0.05）. Conclusion The most significant c
