Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patient-determined education has content designed by patients and clinicians:
Attending clinician will deliver Patient-determined Education package during routine baseline clinical eye exam:
- Will involve 5 to 10 minutes of face-to-face education on stage of disease diagnosed at this visit plus relevant treatments appropriate to stage (Ex. smoking cessation, use of Amsler Grid, use of eye health supplements or eye injections). Conversations guided primarily by patient questions and interest.
- May involve material to take-home to read. Material (one page brochure) depends on stage of disease diagnosed at this visit plus relevant treatments appropriate to stage (Ex. smoking cessation, use of Amsler Grid, use of eye health supplements or eye injections) based on most recent published evidence. Take home material offered determined by patient interest and questions.
- May be supported by follow-up text message reminders monthly for 6 months post-enrolment. Reminders will focus on treatments relevant to stage of disease diagnosed and may address smoking cessation, use of Amsler Grid, use of eye health supplements or eye injections. Text reminders enrolled determined by patient questions and interests.

Comparator / control treatment
Clinician-determined education has content designed by clinicians (Pragmatic Standard Care, may vary from clinician to clinician):
Attending clinician will deliver Clinician-determined Education package during routine baseline clinical eye exam:
- Will involve 5 to 10 minutes of face-to-face education on stage of disease diagnosed at this visit plus relevant treatments appropriate to stage (Ex. weight loss, exercise, healthy eating, smoking cessation, use of Amsler Grid, use of eye health supplements or eye injections). Conversations guided primarily by clinician determination of patient's need as per clinician's standard practice.
- May involve material to take-home to read. Material (one page brochure) depends on stage of disease diagnosed at this visit plus relevant treatments appropriate to stage (Ex. weight loss, exercise, healthy eating, smoking cessation, use of Amsler Grid, use of eye health supplements or eye injections) . Content of take home material and whether it is offered to patient is determined by clinician as per their standard practice.
- May be supported by follow-up text message reminders monthly for 6 months post-enrolment. Reminders will focus on treatments relevant to stage of disease diagnosed and may address weight loss, exercise, healthy eating, smoking cessation, use of Amsler Grid, use of eye health supplements or eye injections. Text reminders that patient is enrolled to receive is determined by clinician as per their standard practice.

Summary
Brief summary
The research study aims to understand if patients' attitudes towards appropriate care for their Age-related Macular Degeneration can be altered based on the type of education they receive. Two different approaches to providing patient education will be provided. This study will help us understand what type of education helps patients accept care that is best for them. If one approach to education is found to be better, we will share our educational approach with other eye health professionals so that they can help their patients make better care decisions too.
