Turkish Version of the Glaucoma Quality of Life-15 Questionnaire

Reliability and Validity of the Turkish Version of the Glaucoma Quality of Life-15 Questionnaire

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.
