AI Summary
This study developed a glaucoma QOL questionnaire, finding age and inferior visual field loss impact direct disability, while medical/surgical treatments relate to indirect disability (worry/anxiety).
Abstract
Purpose
To construct a new item bank to measure quality of life (QOL) in glaucoma patients and to evaluate glaucoma patients' QOL using the item bank.
Methods
An item bank of questions was generated through a literature review of QOL instruments useful for glaucoma patients. Using this item bank, a cognitive survey was performed on 203 patients with glaucoma (112 males and 91 females, 61.9±11.9 y old; mean±SD). The results were then analyzed using the Rasch analysis, and the Rasch-derived disability scores were predicted using linear modelling and the following clinical parameters: age, mean total deviation (mTD) in superior and inferior visual field (mTDsup/mTDinf), mTD progression rate, better visual acuity, worse visual acuity, number of eye drops administered per day, number of trabeculectomy procedures experienced in both eyes.
Results
A total of 23 questionnaires of QOL in glaucoma patients were identified resulting in an item bank of 187 questions related to the following tasks: reading/writing, walking, going out, eating and driving (direct disability) as well as questions concerned with worry/anxiety, social participation, and physical symptoms (indirect disability). In the optimal model for direct disability, age and mTDinf were identified as significant predictors, whereas number of eye drops administered per day and number of trabeculectomy experienced were included in the optimal model for indirect disability.
Conclusions
A new item bank to measure QOL in glaucoma patients was developed and evaluated. Age and mTDinf were found to be related to direct disability while medical and surgical treatments were related to indirect disability.

Age and mean total deviation in the inferior visual field (mTDinf) were identified as significant predictors in the optimal model for direct disability in a study of 203 glaucoma patients.
The number of eye drops administered per day and the number of trabeculectomy procedures experienced were included in the optimal model for indirect disability in a study of 203 glaucoma patients.
An item bank of 187 questions was generated to measure quality of life (QOL) in glaucoma patients, covering direct disability tasks (reading/writing, walking, going out, eating, driving) and indirect disability concerns (worry/anxiety, social participation, physical symptoms).
In a cognitive survey of 203 glaucoma patients (112 males, 91 females, mean age 61.9±11.9 years), Rasch analysis was used to evaluate glaucoma patients' quality of life (QOL) using a newly constructed item bank.
