目的：为了调查色素性视网膜炎 (RP) 患者的日常任务表现功能，目标是 (1) 量化临床视力测试、自我报告和实际任务表现评估之间的关系，以预测这些任务的难度； (2) 通过经过认证的低视力专家对实际任务表现的观察和测量来验证有关日常任务表现的自我报告问卷数据。设计：一项横断面研究和调查。参与者：62 名 RP 个体（平均年龄，37 岁）参与了这项研究。方法：我们从受试者关于其日常表现的报告（通过 53 项问卷评估）和专家对 64 项实际能力的评级中获得了有关任务表现的数据。一系列任务，包括与问卷评估类似的任务。 主要结果测量：视力的临床测量包括视力、使用 Goldmann 视野检查的视野、字母对比敏感度以及视锥细胞和视杆细胞视网膜电图 (ERG) 功能。问卷和功能任务分为三类：“阅读”、“移动”和“外围检测”。结果：自我报告与实际任务表现显着相关。任务表现与临床测试表现显着相关。仅当视力低于 20/40 时，才会观察到中度或更差的表现困难； log对比敏感度小于1.4，视野面积小于2000deg(2)（相当于Goldmann II-4-e目标视野50度直径的面积）；对于 32 Hz 光适应白色闪烁，ERG 幅度小于 10 微伏。结论：尽管存在显着相关性，但任务表现仍然存在差异，而在一些临床测试表现水平较低的个体中，这种差异是无法解释的。对实际任务绩效的评估验证了 RP 个体自我报告的使用。眼科 2001；108:65-75 (C) 2001 年，美国眼科学会。
Purpose: To investigate the functioning in daily task performance of individuals with retinitis pigmentosa (RP), Goals were (1) to quantify the relationships among clinical tests of vision, seif-reports, and evaluations of actual task performance to predict difficulty in these tasks; and (2) to validate self-report questionnaire data about daily task performance with observations and measurements of actual task performance conducted by a certified low-vision specialist.Design: A cross-sectional study and survey.Participants: Sixty-two individuals with RP (mean age, 37 years) participated in the study.Methods: We obtained data about task performance from subjects' reports about their daily performance as assessed by a 53-item questionnaire and from a specialist's rating about actual ability on a 64-item battery of tasks, including ones similar to those assessed with the questionnaire.Main Outcome Measures: Clinical measures of vision included visual acuity, visual fields using Goldmann perimetry, letter contrast sensitivity, and cone and rod electroretinogram (ERG) function. The questionnaire and functional tasks were clustered into three categories: "reading," "mobility," and "peripheral detection."Results: Self-report was correlated significantly with actual task performance. Task performance was correlated significantly with clinical test performance. Moderate or worse difficulty in performance was observed only for visual acuity worse than 20/40; log contrast sensitivity less than 1.4, a visual field area smaller than 2000 deg(2) (area equivalent to a 50-degree diameter of visual field to the Goldmann II-4-e target); and ERG amplitudes less than 10 microvolts for 32-Hz light-adapted white flicker.Conclusions: Despite the significant correlations, there remains variability in task performance that is unaccounted for in some individuals with low levels of clinical test performance. The assessment of actual task performance validated the use of self-reports in individuals with RP. Ophthalmology 2001;108:65-75 (C) 2001 by the American Academy of Ophthalmology.
