“…The data were analysed based on the Long-form Visual Functioning Scale 25 (LFVFS 25 ) and the Long-form Socioemotional Scale 25 (LFSES 25 ). 19 Correlation between age and the score was assessed using Pearson's correlation. Association between sex and the score was analysed using Student's t-test.…”

Aims To assess the vision-related quality of life of corneal transplant recipients using the National Eye Institute Visual Function Questionnaire-25 (NEI VFQ-25), and to identify the socio-demographic factors that associate with patients' self-assessment of perceived visual function. Methods Thirty patients who received corneal transplants were included in this prospective observational, cross-sectional study. Socio-demographic and clinical data, including age, sex, systemic health status, employment status, visual acuity, reason of corneal transplantation, laterality of corneal graft, and follow-up period were collected. NEI VFQ-25 was scored using Rasch analysis. Subgroup analyses were also performed. Results Age, sex, visual acuity, and health status had no significant correlation or association with the Rasch-transformed score. Patients who received bilateral corneal grafts were significantly less able socioemotionally than those with unilateral graft. Patients who became unemployed or retired after transplantation were also significantly less able in both visual functioning and socioemotional status. Conclusion Corneal transplant recipients had a decreased vision-related quality of life as demonstrated by the NEI VFQ-25. Apart from anatomical success and visual acuity, ophthalmologists should also consider other aspects of visual outcome. In particular, those who received bilateral grafts require more attention. Employment programmes should be part of corneal transplantation rehabilitation planning.

“…Other investigators convincingly demonstrated by using modern psychometric techniques that the original tool should be adapted and revalidated. 41,56 The TSS-IOP pops up as the highest quality instrument to assess side effects across different topical treatments, 48,49 yet might be improved as well using Rasch-analysis. If interested in assessing adherence with eye drop treatment, both the adherence questionnaire of Schwartz et al and the EDSQ should be improved, given that both intend to predict nonadherence, but that the discrimination between adherent and nonadherent patients remains difficult.…”

The aim of this review was to summarize literature in view of patient-reported outcome (PRO) instruments for glaucoma and provide guidance on how outcomes are best assessed based on evidence about their content and validity. A systematic literature review was performed on papers describing the developmental process and/or psychometric properties of glaucoma or vision-specific PRO-instruments. Each of them was assessed on their adherence to a framework of quality criteria. Fifty-three articles were identified addressing 27 PRO-instruments. In all, 18 PRO's were developed for glaucoma and 9 for diverse ophthalmologic conditions. Seven instruments addressed functional status, 11 instruments quality of life and 9 instruments disease and treatment-related factors. Most of the instruments demonstrated only partially adherence to predefined quality standards. The tools for assessing functional status were of poor quality, while the Glaucoma Quality of Life Questionnaire and the Vision Quality of Life Index were well-developed QoL measures, yet only validated using classical techniques. The Rasch-scaled QoL-tools, IVI and VCM1 need to improve their item-content for glaucoma patients. The questionnaires to measure adherence should improve their validity and the Treatment Satisfaction Survey for Intra Ocular Pressure pops out as the highest quality tool for measuring topical treatment side effects. This review revealed that most PRO-instruments demonstrated poor developmental quality, more specifically a lack of conceptual framework and item generation strategies not involving the patients' perspective. Psychometric characteristics were mostly tested using classical validation techniques.

“…In this study we are starting from a comprehensive list of DLAs. We used existing DLA surveys and scales that are used to assess visual functioning, such as the Glaucoma Quality of Life questionnaire (Gothwal et al 2012;Khadka et al 2011), Impact of Vision Impairment scale (Lamoureux et al 2008), NEI-RQL 42 questionnaire (McAlinden et al 2012), Catquest-9SF (Lundström & Pesudovs 2009), NEI-VFQ (Pesudovs et al 2010a;Pesudovs et al 2010b), DLTV (Schmier & Halpern 2006), and the VA LV VFQ (Stelmack & Massof 2007).…”

Currently, ICT applications and devices like 'smart glasses', are hitting the consumer market. These devices offer great potential for people with disabilities, such as the visually impaired, but only when they are accessible for all users. This study comprehends a user-centered design process thoroughly analysing the needs and priorities of the prospective users. In order to assess the possibilities and limitations of smart devices for people with visual impairments, we created a priority list for to-bedeveloped functions and apps based on different empirical studies, including an interview and a survey. We propose that both designers and developers use this list as a starting point for generating or assessing the feasibility of new ideas for apps for the visually impaired.
