Glaucoma, Quality of Life
Conditions
Brief summary
Glaucoma is a disease with irreversible loss of visual field and optic neuropathy and is the most important cause of irreversible vision loss after cataract in the world. Although clinical evaluations reveal the level of glaucoma quantitatively, it is necessary to evaluate the impact of this pathology on daily functions and quality of life with a holistic perspective and to provide appropriate advice to patients according to the information obtained. Glaucoma Quality of Life -15 Questionnaire (GQoL-15) was developed by Nelson et al. in 2003 to evaluate the quality of life of glaucoma patients. The aim of this study is to translate GQoL-15 into Turkish and evaluate its test-retest reliability for Turkish-speaking population.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Glaucoma Quality of Life 15 Questionnaire total score | 6 months | GQoL-15 total score was got after calculate the all subscale values. Subscales are as; 1) Central and near vision (two questions); 2) Peripheral vision (six questions); 3) Dark adaptation (six questions); 4) Outdoor mobility (one question). The item responses for each factor are marked on a five-point scale (1 meaning no difficulty and 5 meaning severe difficulty), 0 is marked if the participant does not perform the activity because of non-visual causes. Higher GQL-15 total scores and subscale scores are reveals lower QoL. |
| 25-item National Eye Institute Visual Functioning Questionnaire (NEI-VFQ 25) | 6 months | NEI-VFQ 25 total score was got after calculate the all values. It is comprised of 25 items which are; general health and vision, ocular pain, difficulty with vision activities, distance-vision activities, limitation of social functioning, mental health problems, role limitations, dependency on others, driving difficulties, difficulty with color vision and difficulty with peripheral vision. A total score of NEI-VFQ 25 is generated by averaging the scores of all subscales except general health. The item responses for factors are marked on a five or six point scale. Subscale score can be calculated, overall total lower score indicates better vision-related QoL. |
