摘　　要：目的研究电脑防护滤光镜(CLF)对视网膜色素变性(RP)患者视觉质量的影响。设计前瞻性病例系列。研究对象2018年3月至2018年6月温州医科大学附属眼视光医院低视力中心双眼RP患者22例。方法所有患者均进行屈光不正矫正,使用Mars对比敏感度表测量戴CLF前后的明视对比敏感度,使用计时器计时阅读电脑显示屏上相同文字段所需时间,使用评分表对戴镜后阅读显示屏的舒适度、明亮度进行评分。主要指标对比敏感度、阅读速度、视觉舒适度、明亮度。结果戴CLF前患者舒适度评分设置为0,戴镜后视觉舒适度明显提高,为4.0±2.8(t=6.897,P<0.001);戴CLF前患者对显示屏的亮度感觉评分设置为0,戴CLF后主观感觉显示屏明亮度明显降低,为-2.8±2.4(t=-5.412,P<0.001);戴CLF前患者的明视对比敏感度为(1.0±0.5)logCS,戴CLF后无明显变化,为(1.0±0.5)logCS(t=0.68,P=0.504);戴CLF前患者显示屏阅读速度为(209.1±95.0)字/分钟,戴CLF后无明显提高,为(210.2±92.8)字/分钟(t=-0.233,P=0.826)。结论CLF能提高RP患者电脑显示屏阅读舒适度,降低显示屏亮度。Objective To explore the effects of a computer lens filter(CLF)on patients with retinitis pigmentosa(RP)on visual quality.Design Prospective case series.Participants A total of 22 patients with binocular RP were studied in the Low Vision Center of the Optometry Hospital affiliated to Wenzhou Medical University from March 2018 to June 2018.Methods All patients underwent re-fractive error correction.Mars contrast sensitivity table was used to measure the bright contrast sensitivity before and after wearing the CLF,the time required to read the same text on the computer screen was measured with a timer.The comfort and perception for the brightness of the display screen after wearing the CLF were scored with a score table.Main Outcome Measures Bright contrast sensi-tivity,reading speed,visual comfort,perception for brightness.Results The visual comfort score of RP patients before wearing CLF was set to 0,after wearing CLF it significantly increased to 4.0±2.8(t=6.897,P<0.001).The perception score for the brightness of display of RP patients before wearing CLF was set to O,and after wearing the CLF it decreased significantly,which was-2.8±2.4(t=-5.412,P<0.001).The bright contrast sensitivity was 1.0±0.5 logCS in RP patients before wearing the CLF,but no significant change was 1.0±0.5 logCS after wearing the CLF(t=0.68,P=0.504).The screen reading speed of RP patients before wearing CLF was 209.1±95.0(words/min),which was not significantly improved after wearing CLF,and was 210.2±92.8(words/min)(t=-0.233,P=0.826).Conclusion CLF can improve the reading comfort of computer display screen and reduce the perception of brightness of display screen for RP patients.
