计算机视觉综合征患者眼调节功能的客观检查研究

目的 用客观检测方法检查计算机视觉综合征患者的眼调节功能。设计 回顾性病例系列。研究对象 北京同仁医院视光学门诊计算机视觉综合征患者58例。方法 除视力检查、显然验光、复方托吡卡胺散瞳验光、眼镜度数检查、主观调节幅度检查外，使用Nidek AA-1人眼调节分析仪客观检测计算机视觉综合征患者的眼调节功能。主要指标 调节幅度、调节滞后量和调节微波动的高频成分（HFC）。结果 调节幅度检查显示24例（41.38%）调节幅度降低。客观调节功能检查显示41例（70.69%）存在调节功能异常，其中10例（17.24%）调节滞后；14例（24.14%）调节微波动HFC增加，包括调节紧张11例（18.97%）、调节痉挛3例（5.17%）； 17例（29.31%）调节滞后和调节微波动HFC增加同时存在，包括调节滞后伴调节紧张14例（24.14%），调节滞后伴调节痉挛3例（5.17%）。结论 本小样本的回顾性病例系列显示，计算机视觉综合征患者多数存在调节功能异常，其异常类型以调节滞后和调节紧张为主。（眼科， 2013, 22： 335-339）

Objective examination of accommodative function of computer vision syndrome

Objective To examine the accommodative function of computer vision syndrome with an objective method. Design Retrospective case series. Participants 58 computer vision syndrome patients who were treated in optometry clinic of Beijing Tongren Hospital. Methods In addition to visual acuity, direct refraction, cycloplegic refraction, spectacles lenses test and subjective accommodative amplitude test, objective measurement of accommodative function was administered, using the Nidek AA-1 accommodative analyzer of human eyes. Main Outcome Measures Accommodative amplitude, the lag of accommodation and high frequency component (HFC) of accommodative microfluctuations. Results In the subjective accommodative amplitude test,  the amplitude of accommodation  in 24 out of 58 cases (41.38%) were reduced. In the objective accommodative function test, accommodative dysfunction happened in 41 cases (70.69%) in which,  accommodative lag was detected in 10 cases (17.24%); HFC of accommodative microfluctuations increased in 14 cases (24.14%), including 11 cases (18.97%) with accommodative strain and 3 case (5.17%) with accommodative spasm; 17 cases (29.31%) was found with the accommodative lag combined with increasing HFC, including 14 cases (24.14%) with accommodative lag and accommodative strain  and 3 cases (5.17%) with accommodative lag and accommodative spasm. Conclusion This small sample retrospective case series shows that most of computer vision syndrome patients have accommodative dysfunction, in which is the accommodative lag and accommodative strain is most common.
