目的 探讨影响电焊作业工人黄斑视觉功能损害发生的相关危险因素.方法 选择2010年8月-2013年12月本地电焊作业的工厂中专职电焊工86例172眼作为研究对象.眼部检查:包括最佳矫正视力、90 D前置镜眼底检查、眼底彩照和OCT检查,光损伤性黄斑病变的诊断以OCT的检查结果为准.将受试者按年龄、防护程度、工龄和工作时间分组,比较各组间光损伤性黄斑病变的检出率.再将受试者随机分为叶黄素干预组和安慰剂对照组,检测最佳矫正视力、黄斑色素密度值、对比敏感度及眩光敏感度.结果 (1)光损伤性黄斑病变总发病率为32.0％,与年龄无相关性(统计学结果).(2)防护习惯不同各组间光损伤性黄斑病变的发生率分别是21.4％,36.7％,53.6％,采用严格防护者,检出率低于其他两组,非专业防护者检出率最高,三组间差别有统计学意义.(3)随着工龄和每天工作时间的延长,光损伤性黄斑病变的发生率逐渐提高,差别有统计学意义.(4)叶黄素干预组在最佳矫正视力、MPOD和对比敏感度及眩光敏感度方面,显著优于安慰剂对照组.结论 电焊工人中黄斑光损伤的危险相关因素是工龄、工作时间、防护习惯和叶黄素的是否辅助使用,所以应该在这些方面加强.
目的 探討影響電銲作業工人黃斑視覺功能損害髮生的相關危險因素.方法 選擇2010年8月-2013年12月本地電銲作業的工廠中專職電銲工86例172眼作為研究對象.眼部檢查:包括最佳矯正視力、90 D前置鏡眼底檢查、眼底綵照和OCT檢查,光損傷性黃斑病變的診斷以OCT的檢查結果為準.將受試者按年齡、防護程度、工齡和工作時間分組,比較各組間光損傷性黃斑病變的檢齣率.再將受試者隨機分為葉黃素榦預組和安慰劑對照組,檢測最佳矯正視力、黃斑色素密度值、對比敏感度及眩光敏感度.結果 (1)光損傷性黃斑病變總髮病率為32.0％,與年齡無相關性(統計學結果).(2)防護習慣不同各組間光損傷性黃斑病變的髮生率分彆是21.4％,36.7％,53.6％,採用嚴格防護者,檢齣率低于其他兩組,非專業防護者檢齣率最高,三組間差彆有統計學意義.(3)隨著工齡和每天工作時間的延長,光損傷性黃斑病變的髮生率逐漸提高,差彆有統計學意義.(4)葉黃素榦預組在最佳矯正視力、MPOD和對比敏感度及眩光敏感度方麵,顯著優于安慰劑對照組.結論 電銲工人中黃斑光損傷的危險相關因素是工齡、工作時間、防護習慣和葉黃素的是否輔助使用,所以應該在這些方麵加彊.

Objective To investigate the Influence of risk factors that cause the phototoxic maculopathy by welding arc in occupational welders.Methods We examined randomly a group of 86 male occupational welders 172 eyes from some local metal manufacturing enterprise from August 2010 to December 2013.The ophthalmologic examination which the participants underwent thorough including the best visual acuity,fundus examination by the supplementary lens,fundus photography,and the high definition optical coherence tomography (OCT) scan.All participants of this study underwent thorough the medicine examined by a specialist of occupational who prior to the OCT.All the subjects were divided into groups according to age,protection degrees,length of service,operating time.The incidences of phototoxic maculopathy were compared within groups.The subjects was divided randomly into the lutein group and the placebo group.The examination including the best visual acuity,serum lutein concentrations,macular pigmentoptical density (MPOD),Contrast and glare Sensitivity.Results (1)The total incidence of phototoxic maculopathy is 32.0％.(2)The incidences of phototoxic maculopathy in the strict protection group,the randomed protective group and the nonprofessional protection group were respectively 21.4％,36.7％,53.6％.The incidence in the strict protection group was lower than the other two groups,the incidence was the highest in the nonprofessional protection group,and the difference was statistically significant.(3) The longer length of service,and operating time,the more incidence of phototoxic maculopathy develop.(4) The lutein group prior to the placebo group at the best visual acuity,serum lutein concentrations,macular pigmentoptical density(MPOD),Contrast and glare Sensitivity.Conclusion The risk factors of phototoxic maculopathy in male occupational welders are the length of service,operating time,protection degrees and the lutein assistantly.The incidence of phototoxic maculopathy occurs regardless of age.
