Abstract

Background: Researchers have found that the refractive states of the eye are influenced by a variety of variables. Aim: This study investigated the correlation between the central corneal power (CCP) and a number of variables, which include axial length (AL), anterior chamber depth (ACD) and the central corneal thickness (CCT) in near-emmetropic eyes of students. Setting: The study was conducted in the Optometry Laboratory of the Islamic University-Gaza (IUG), Palestine. Methods: In a prospective analysis, 200 near-emmetropic students were examined from February 2019 to May 2019 with an ultrasound scanner (A-scan), ultrasonic pachymeter and Visionix L79 automated refractometer Keratometer (ARK). Only the data of one eye were randomly chosen for investigation. Results: The means and standard deviations (s.d.) of the CCP, AL, ACD and CCT for male students ( n = 97) were 43.19 dioptre (D) ± 1.34 D, 23.54 mm ± 0.68 mm, 3.59 mm ± 0.26 mm and 549 µm ± 33 µm, respectively. Furthermore, the means ± s.d. of 103 female students were as follows: CCP 43.85 D ± 1.43 D, AL 22.94 mm ± 0.69 mm, ACD 3.35 mm ± 0.25 mm and CCT 543 µm ± 35 µm. There was a significant association between CCP and gender ( p = 0.00). There was a negative significant correlation between CCP and AL for both the male ( r = −0.64; p = 0.00) and the female ( r = −0.71, p = 0.00) participants. Conclusion: This study provided information on CCP, AL, ACD and CCT in near-emmetropic eyes of adults. In male students, CCP was flatter and AL was longer when compared with female Palestinian students.
巴勒斯坦近远视青年大学生角膜中央度数、轴长、前房深度和角膜中央厚度的相关性
背景:研究人员发现,眼睛的屈光状态受到多种变量的影响。目的:探讨学生近远视眼角膜中央度数(CCP)与眼轴长(AL)、前房深度(ACD)和角膜中央厚度(CCT)的相关性。环境:本研究在巴勒斯坦加沙伊斯兰大学(IUG)验光实验室进行。方法:在前瞻性分析中,于2019年2月至2019年5月对200名近屈光性学生进行了超声扫描仪(a -scan)、超声测厚仪和Visionix L79自动屈光计角膜屈光计(ARK)检查。只随机选取一只眼的数据进行调查。结果:97名男学生CCP、AL、ACD、CCT的均值和标准差分别为43.19 dioptre (D)±1.34 D、23.54 mm±0.68 mm、3.59 mm±0.26 mm和549µm±33µm。103名女大学生的平均±标准差为:CCP 43.85 D±1.43 D, AL 22.94 mm±0.69 mm, ACD 3.35 mm±0.25 mm, CCT 543µm±35µm。CCP与性别有显著相关(p = 0.00)。男性CCP与AL呈显著负相关(r = - 0.64;P = 0.00)和女性参与者(r = - 0.71, P = 0.00)。结论:本研究提供了成人近远视眼CCP、AL、ACD和CCT的相关信息。与巴勒斯坦女学生相比,男学生CCP较扁平,AL较长。
