“…Reliable assessment of the impact of ophthalmic diseases on the visual-related quality of life must take into account specific cultural aspects of different populations (1) .

“…As the need to develop instruments to measure both general and specific visual disorders has been recognized by the scientific community, in the mid-1990s the National Eye Institute (NEI) funded the development of a vision-specific HRQOL instrument, called the National Eye Institute 51-Item Visual Functioning Questionnaire (NEI VFQ-51) (1) . Later on, a shorter version was developed: the NEI VFQ-25, to become useful in clinical practice and improve data quality.…”

Purpose: To develop and investigate the reliability and validity of a Brazilian version of the 25-Item National Eye Institute Visual Function Questionnaire. Methods: A Brazilian version of the questionnaire was developed and applied to patients with chronic eye diseases and healthy controls. Reliability was assessed by Cronbach's alpha coefficient, intraclass correlation coefficient and interrater reliability coefficient. Participants were submitted to the Medical Outcomes Study Short Form-36 Questionnaire. Validity was estimated by the correlation between the questionnaires and among the 12 subscales of the questionnaire, subscales scores and visual acuity, patients' and controls' subscales scores, and the factor analysis. Responsiveness of the questionnaire was assessed in a group of patients before and following cataract surgery. Results: Cronbach's alpha, intraclass correlation and interrater reliability coefficients were highly significant. Validity was well established in all tests. In patients who underwent cataract surgery, a better visionrelated quality of life was observed following surgery. Conclusion: The Brazilian version of the 25-Item National Eye Institute Visual Function Questionnaire has valid and reliable psychometric properties and can be applied to vision-related quality of life research.

“…Outcome measurement is also improved because IRT generates scores on an interval scale, unlike the classic Likert scales, 42 and it has been suggested to provide a more robust approach to the interpretation of rating scales. 134 The choice of items in any self-rated outcome measure is also of great importance -a positive effect will only be found if the items included are responsive to the treatment. 140 In future, the development and rigorous validation of scientifically sound outcome measures must be a high priority of the field and a major criterion for judging the quality of a study.…”

This is the unspecified version of the paper.This version of the publication may differ from the final published version. Permanent repository link Abstract.Visual impairment is a large and growing socioeconomic problem. Good evidence on rehabilitation outcomes is required to guide service development and improve the lives of people with sight loss.Of the 478 potentially relevant articles identified, only 58 studies met our liberal inclusion criteria, and of these only 7 were randomized controlled trials. Although the literature is sufficient to confirm that rehabilitation services result in improved clinical and functional ability outcomes, the effects on mood, vision-related quality of life (QoL) and health-related QoL are less clear. There are some good data on the performance of particular types of intervention, but almost no useful data about outcomes in children, those of working age and other minority groups. There were no reports on cost effectiveness. Overall, the number of well designed and adequately reported studies is pitifully small; visual rehabilitation research needs higher quality research. We highlight study design and reporting considerations and suggest a future research agenda.

“…2 Jani 3 noted an increase in stereoacuity from ages 9-20 years and then a considerable reduction of stereoacuity over the age of 40 years in a volunteer study of stereopsis using the Diastereo test. While visual impairment was shown to reduce the quality of life [4][5][6][7][8][9] and can cause clinical depression 10,11 in the elderly, little was known about whether reduced stereopsis would induce any vision-related functional impairment and affect the well-being and general health status of the elderly. In this study, we aim to explore the relationship between defective stereopsis and quality of life in the elderly.…”

Purpose To investigate the impact of stereopsis on vision-related quality of life and general health status of the elderly. Methods A quota of 200 subjects aged 65 years or older and had their households registered in Guando district was recruited for a general physical examination including ophthalmic evaluation. A structured questionnaire consisting of seven visionspecific items as well as 36-item short-form survey of the Medical Outcomes Study (SF-36) was administered. Stereoscopic level was divided into three groups: no stereopsis, gross stereopsis, and fine stereopsis. Fisher's exact test was used to detect any difference in subjective visual functioning and Mann-Whitney U test was used for analyses of SF-36 scores. Results A total of 187 volunteers were recruited and 150 were analysed for stereoscopic levels. There was no significant difference in vision-specific difficulty among the three stereoscopic groups. For SF-36, having no stereopsis scored significantly less than having gross (P ¼ 0.005) and fine (Po0.0001) stereopsis in the vitality/energy dimension. General health perception dimension fared significantly lower in the group with no stereopsis compared to the fine stereoscopic group (P ¼ 0.01). In multivariate analysis, having fine stereopsis scored significantly higher in the energy/vitality dimension than having no stereopsis (P ¼ 0.02). On the other hand, visual impairment imposed significant adverse effect on five vision-specific items and had no significant relationship with the eight dimensions of SF-36. Conclusions Defective stereopsis in the elderly imposes no significant adverse effect on vision-related quality of life. However, subjects may feel more exhausted in accomplishing their usual tasks.
