“…As a rare instrument originally developed for a developing country-India-the 33-item Indian Vision Function Questionnaire (IND-VFQ-33) has been used across different eye conditions such as uveitis, 7,8 corneal diseases, 9 cataract, 10 and primary glaucoma. 11,12 Like most ophthalmological instruments, it was developed and proved to possess good reliability and validity using the classical test theory (CTT). 13 Finger et al 14 and Gothwal et al 15 have verified its psychometric properties in Indian patients using the Rasch analysis, and they proved it to be an effective tool.…”

The purpose of this study was to assess whether a Chinese translated version of the 33-item Indian Vision Function Questionnaire (IND-VFQ-33) forms a valid measurement scale and to evaluate its psychometric properties based on the method of successive dichotomizations (MSD). Methods:The English version of the IND-VFQ-33 was translated, back translated, and cross-culturally adapted for use in China. It was interviewer administered to patients with cataracts. MSD, a polytomous Rasch model that estimates ordered thresholds, was used to assess and optimize psychometric properties of the overall scale and three subscales separately.Results: One hundred and seventy-nine patients provided complete responses. After the removal of 2 misfitting items, a revised 31-item overall scale demonstrated adequate precision (person reliability [PR] = 0.92) and no misfitting items. The general functioning subscale fit the MSD model well after removing two misfitting items. The psychosocial impact subscale and the visual symptoms subscale were not considered further due to poor measurement precision. After addressing psychometric deficiencies, a 31-item overall scale (IND-VFQ-31-CN) and a 19-item general functioning subscale (IND-VFQ-GF-19-CN) were developed. Conclusions:The original IND-VFQ-33 required re-engineering to form valid measures for use in China. The revised overall scale and general functioning subscale demonstrated adequate MSD based psychometric properties. Translational Relevance:The revised IND-VFQ-33 is a valid patient-reported outcome assessment for Chinese patients with cataract based on MSD analysis.

Precis: Glaucoma patients displayed alterations in their quality of life (QoL) and their ability to perform activities of daily living. The visual field (VF) of the worse eye might serve as a good marker for QoL evaluation. Purpose: The purpose of this study was to explore the correlations between VF defects, performance in simulated activities of daily living, and subjective evaluation of QoL in glaucoma patients. Methods: Thirty-two patients with glaucoma and 10 age-matched control subjects were included. All participants answered a QoL questionnaire and underwent an assessment of visual function including monocular and binocular best-corrected visual acuity, binocular contrast sensitivity test (LogCS), and monocular and binocular VF. All subjects also carried out a series of simulated activities of daily living in a controlled environment. Results: Glaucoma patients had lower QoL scores compared with controls for the composite score, near and distance activities, social functioning, mental health, role difficulties, dependency, and color vision. With regard to performance in the simulated mobility task, the number of mobility incidents was higher for glaucoma patients than for control subjects. For the reaching and grasping tasks, the overall movement duration for small objects was significantly longer in glaucoma patients compared with controls. The VF mean deviation of the worse eye was correlated with most of the QoL subscores. Mobility incidents as well as the reaching and grasping task parameters were not significantly correlated with QoL scores. Conclusions: Glaucoma patients showed an alteration of performance in simulated daily living activities, associated with a decreased QoL. There was no clear correlation between alterations in QoL and ability to perform activities of daily living. The QoL related to vision was mostly correlated to the visual function of the worse eye.
