显微镜工作者近视和双眼视力障碍的患病率分析

Prevalence of myopia and binocular vision dysfunctions in microscopists

摘要:

目的：测定临床显微镜工作者屈光和双眼视力状态。

方法：这是一项以医院为基础的观察性和横断面研究。研究包括103位在特里布文教学医院工作的显微镜工作者。受试者均行全面的眼部检查，包括静态检影，动态检影和视轴评估。收集受试者显微镜下视觉状态信息。

结果：该组显微镜工作者屈光不正患病率为69.90%。68.93%受试者近视，平均近视误差为-1.58±1.89 D。研究发现61.20%受试者汇聚功能不全。调节不足与调节功能不全的发病率分别为41.30% 和40.06%。研究人群的融合性转向也有所降低。

结论：研究发现，临床显微镜工作者屈光不正尤其是近视的患病率增加。其中大多数有转斜和调节不足。大多数受试者视疲劳症状与其显微镜工作有关，这可能会影响他们的工作效率。

Abstract:

AIM: To determine the refractive and binocular vision status in clinical microscopists.

METHODS: It was an observational and cross sectional hospital based study. One hundred and three microscopists working at Tribhuvan University Teaching Hospital were recruited in the study. All subjects had a comprehensive eye examination including static retinoscopy, dynamic retinoscopy and orthoptic evaluation. Information about their visual symptoms associated with microscopy was also collected.

RESULTS: The prevalence of refractive error in this group of microscopists was 69.90%. Majority of the subjects were myopic(68.93% of total subjects)with the mean myopic error of -1.58±1.89 D. Convergence insufficiency was found in 61.20% of the study population. Prevalence of accommodative insufficiency and infacility were 41.30% and 40.06% respectively. Fusional vergence was also reduced in this study population. The outcomes of this study were expected to increase the awareness about the refractive and binocular vision anomalies among this population.

CONCLUSION: There was found to be increased prevalence of refractive error in clinical microscopists, especially myopia. Majority of them had vergence and accommodative anomalies. Most of the subjects reported asthenopic symptoms associated with their microscopy work, which may affect their work efficiency.
