How Has Glaucoma Affected Your Quality of Life?
A Prospective, Longitudinal, Observational Cohort Study Examining How Glaucoma Affects Quality of Life and Visual Function Over a 4-Year Period
Hypothesis 1: Self-reported health-related quality of life decreases as vision impairment worsens in subjects with glaucoma.
Hypothesis 2: Changes in health-related quality of life are associated with changes in clinical measures of vision and performance-based measures of visual function.
調査の概要
状態
詳細な説明
You are being asked to participate in this research study because you have glaucoma, which is the second leading cause of blindness in the world and accounts for 15% of blindness worldwide. Vision loss caused by glaucoma can significantly worsen your health-related quality of life. Despite the fact that glaucoma has such a big impact on a large number of people, research examining the long-term effects of glaucoma-related vision loss on one's quality of life is scarce.
The purpose of this study is to look at the long-term effect of this condition on your quality of life so that we may gain valuable information about what factors influence the quality of life of people with glaucoma. To participate in this study, you will need to allow us to perform clinical tests on your eyes, to self-report your well-being and health-related quality of life, and to let us know how well you perform your daily life activities.

他の:Glaucoma Patients
Moderate glaucoma patients with a minimum 2-year diagnosis of primary open-angle glaucoma, chronic primary angle-closure glaucoma or pseudoexfoliation glaucoma were included to complete annual visits over a 4 year period.
Each visit included (1) Clinical evaluation: a slit lamp examination, fundoscopy, intraocular pressure measurement, visual field examination, spectral domain optical coherence tomography, Pelli-Robson Contrast Sensitivity test and the Spaeth-Richman Contrast Sensitivity test; (2) a performance based measures: the Compressed Assessment of Ability Related to Vision; and (3) Subjective measures of vision-related quality of life (VRQoL) (the National Eye Institute Visual Functioning Questionnaire 25 and the Modified Glaucoma Symptom Scale).

Quality of Life With NEI VFQ-25
時間枠:2 hours at each annual visit, visits 2 through 5
|
National Eye Institute Visual Function-25 questionnaire (NEI VFQ-25) is a measurement of patients perception of their visually related quality of life.
Patients select answers from multiple choice lists of responses.
Values are re-coded and converted to a scale of 0 to 100 where 0 is extreme difficulty and 100 is no difficulty at all (or best quality of life).
Data from visits 2 through 5.

Eye Comfort With MGSS
時間枠:2 hours at each annual visit, visits 2 through 5
|
Modified Glaucoma Symptom Scale (MGSS), is patient perception of their eyes comfort.
Ten ocular complaints often associated with glaucoma each have a four level score (1 signifying very bothersome; 4 represents absence of problems).
Scores from 10 questions are added and range from 0 to 100 where 0 represents significant discomfort and 100 represents no problems at all.
The final MGSS score is an unweighted average of responses to 10 items, averaged between the 2 eyes.
Data from visits 2 through 5.
