Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Ocular Surface Disease Index (OSDI) | At baseline and 3-6 months after glaucoma treatment (i.e. drops, SLT, or surgery) was initiated/performed. | The OSDI© is assessed on a scale of 0 to 4, with higher scores representing greater disability. The index demonstrates sensitivity and specificity in distinguishing between normal subjects and patients with dry eye disease. The OSDI© is a valid and reliable instrument for measuring dry eye disease (normal, mild to moderate, and severe) and effect on vision-related function. |
| Glaucoma Symptom Scale (GSS) | At baseline and 3-6 months after glaucoma treatment (i.e. drops, SLT, or surgery) was initiated/performed. | The Glaucoma Symptom Scale (GSS; Lee et al., 1998) was developed as a brief symptom survey specific for persons with glaucoma. The GSS consists of a 10-item scale developed from a modified version of a symptom checklist that address ocular complaints, some of a nonvisual nature and some of a visual nature, common to patients with glaucoma. Items are scored from 0 to 100, where 100 represents the absence of symptoms and 0 represents severe, bothersome symptoms. |
| National Eye Institute Visual Function Questionaire (NEI VFQ) | At baseline and 3-6 months after glaucoma treatment (i.e. drops, SLT, or surgery) was initiated/performed. | Vision-specific instrument designed to measure vision-related quality of life (VRQoL) in adults, incorporating body, activity, and participation content according to the WHO ICF Framework in order to measure the effects of a variety of ocular conditions on daily functioning and QOL. It was originally designed as a 51-point questionnaire and is currently available in both self-administered and interview-based formats. The raw scores are converted to a 0-100 scale; after reverse scoring, a high score (100) indicates better vision-specific quality of life, while a low score (0) indicates poor function. |
| Glaucoma Quality of Life-15 (GQL-15) | At baseline and 3-6 months after glaucoma treatment (i.e. drops, SLT, or surgery) was initiated/performed. | The Glaucoma Quality of Life-15 (GQL-15) is a validated 15-item, self-report questionnaire used to measure visual disability and quality of life (QoL) in glaucoma patients. It covers four key areas-peripheral vision, central/near vision, glare/dark adaptation, and outdoor mobility-using a 5-point scale (1=no difficulty to 5=severe difficulty). |
