ObjectivesTo compare sociodemographics and vision-related quality of life (QoL) of individuals with or without dry eye disease (DED); and to explore the impact of DED symptom severity on visual function, activity limitations and work productivity.DesignCross-sectional web-based survey.SettingGeneral UK population.ParticipantsAdults ≥18 years with (N=1002) or without (N=1003) self-reported DED recruited through email and screened.Main outcome measuresAll participants completed the 25-item National Eye Institute Visual Function Questionnaire (NEI VFQ-25), with six additional questions (items A3–A8), and the EuroQol 5 dimensions 5 levels. DED participants also completed Impact of Dry Eye on Everyday Life questionnaire, 5-item Dry Eye Questionnaire and the Standardised Patient Evaluation of Eye Dryness questionnaire along with the Ocular Comfort Index, Work Productivity and Activity Impairment and the Eye Dryness Score (EDS), a Visual Analogue Scale.ResultsBaseline demographic and clinical characteristics were similar in participants with versus without DED (mean age, 55.2 vs 55.0 years; 61.8% vs 61.0% women, respectively) based on recruitment targets. Scores were derived from NEI VFQ-25 using the new 28-item revised VFQ (VFQ-28R) scoring. Mean (SD) VFQ-28R scores were lower in participants with versus without DED, indicating worse functioning (activity limitations, 73.3 (12.3) vs 84.4 (12.3); socioemotional functioning, 75.3 (21.5) vs 90.3 (16.2); total score, 71.6 (12.8) vs 83.6 (12.6)). Higher percentages of problems/inability to do activities were observed among those with versus without DED. The impact of DED on visual function was worse for participants with more severe DED symptoms, as assessed by EDS. In addition, a higher EDS was associated with worse symptoms on common DED scales and a worse impact on work productivity.ConclusionsDED symptoms were associated with negative effects on visual function, activities and work productivity, whereas worse DED symptoms had a greater impact on vision-related QoL and work productivity.

Purpose: To investigate visual perception problems (VPPs), health-related quality of life (HRQoL) and vision-related quality of life (VRQoL) in young adults with foetal alcohol spectrum disorders (FASD) and to compare the results with healthy controls. Methods: Thirty young adults with FASD (13 female; mean age 23 years) and 29 controls (20 female; mean age 25 years) participated. Five areas of VPPs were assessed by a structured history-taking. In the FASD group, VPPs were investigated both in childhood (mean age 8 years) and in early adulthood in a prospective follow-up. Health-related quality of life (HRQoL) was investigated with the Pediatric Quality of Life Inventory TM (PedsQL) and VRQoL with the 25-item Visual Function Questionnaire (VFQ-25). Results: Visual perception problems (VPPs) in at least one area were reported by 16/30 FASD participants (53%) and 1/29 controls (3%) (p = 0.0001, Fisher's exact test), with a similar rate in the same individuals in childhood as in early adulthood (8/27 and 15/27, respectively p = 0.09, McNemar's test). PedsQL total score was lower in the FASD group (n = 20; median: 83; 95% confidence interval (CI) 76-88) compared with controls (n = 29; median: 91; 95% CI 90-95; p = 0.0001, Mann-Whitney U-test). VFQ-25 subscale general vision indicated lower VRQoL in the young adults with FASD (n = 19; median: 80; 95% CI 80-100) compared with controls (n = 29; median: 100; 95% CI 100-100; p = 0.003). Conclusion: Young adults with FASD in the present study had more VPPs and worse VRQoL and HRQoL than healthy controls. In the FASD group, VPPs were reported in childhood as well as in early adulthood.

“…Rasch analyses and Item Response Theory are relatively new analyses used to develop, evaluate and improve patient reported outcomes. They might have been relevant in current study, to both evaluate and potentially suggest improvement in items of NEI-VFQ 25 as an previous study has shown in the same population [49]. However, the aim in the present study was not such an extensive evaluation, but rather to validate the original measure in a Norwegian population with nAMD.…”

Background Although visual acuity and optical coherence tomography (OCT) are most widely used as outcomes in treatment of neovascular age-related Macular Degeneration (nAMD), patient reported outcome measures are increasingly recognized. National Eye Institute Visual Function Questionnaire (NEI-VFQ 25) was developed to capture the perceived visual function. Yet, evidence of psychometric performance in the target population is required. The aim of this study was to examine the psychometric properties of NEI-VFQ 25 in a Norwegian cohort of newly diagnosed nAMD patients followed with a Treat and Extend (T/E) protocol. Methods Patients receiving intravitreal anti–vascular endothelial growth factor (anti-VEGF) injection treatment according to a T/E protocol completed a Norwegian translation of NEI-VFQ 25, EuroQoL Health Questionnaire (EQ-5D), and Patient acceptable symptom state (PASS 5) at baseline, 3, 6 and 12 months. In addition, a control population completed the same questionnaires. Visual acuity was assessed with LogMar for best/treated eye. Validity testing comprised face validity by a 0–10 numeric rating scale about relevance of NEI-VFQ 25 as well as regression analyses and correlations between NEI-VFQ 25 and other relevant variables. Reliability was examined with Intraclass Correlation Coefficient (ICC) and Cronbach’s alpha for internal consistency were performed. Responsiveness, discriminatory power and predictive value were also explored. Results Number of respondents at baseline, after 3, 6 and 12 months was 197, 186, 176 and 168, respectively. The control population comprised 26 individuals. Face validity of NEI-VFQ 25 had a mean (SD) of 7.8 (1.7) ( n = 84). NEI-VFQ was significantly correlated to visual acuity and PASS 5 as well as EQ-5D at baseline. Reliability (ICC) of the overall and sub scores for the patients/controls ranged from 0.49–0.97/0.59–0.97. Cronbach’s alpha was 0.61–0.85. Discriminatory power was confirmed by significant differences of the overall score between controls and patients ( P < 0.001). NEI-VFQ 25 indicates responsiveness showing overall score improved significantly ( P ≤ 0.001) from baseline to 3 months. NEI-VFQ 25, general health and visual acuity at baseline were the strongest predictors for how patients reported vision after 6 months follow-up. Conclusion NEI-VFQ 25 showed acceptable psychometric performance, which supports that the Norwegian version can be used to monitor patients treated for nAMD.
