Brief Summary

The positive effects of exercise on ocular health are known, but modern lifestyles have made it difficult to incorporate physical activity into the daily lives of the Chinese population. Recent studies suggest that exercise plays an important role in lowering intraocular pressure (IOP) by protecting retinal ganglion cells (RGCs) in glaucoma patients as well as other potential neuroprotective benefits. Increasing the amount of physical activity within the Chinese glaucoma population may have marked effects on health outcomes and coincides with the Chinese government's efforts to make exercise an urgent public health priority. There is a need for innovative, cost-effective, and proven interventions to promote exercise behavior change and social media platforms may be able to fill this niche. WeChat is China's largest and most frequently used social media and messaging application with an estimated 570 million users. The platform has been found to be a useful tool in healthcare settings to promote weight-loss, health literacy, and patient adherence in Chinese populations. This study is a 5-weeks randomized control trial with three total study visits. 80 patients from an academic glaucoma clinic in Wenzhou Medical College will be randomized into two groups. The intervention group will be enrolled into an Official WeChat Group and receive periodic reminders to exercise, health education materials, and motivational incentives. The control group will receive weekly reminders and leaflets at the first clinic visit. Patients' daily step data will be monitored using an Accelerometer WGT3X-BT. The intervention duration will include an initial clinic visit, a one-week follow-up after wearing the accelerometer, and then a subsequent one-month follow-up visit after wearing the accelerometer. At the one-week visit the patient will be randomized and at the subsequent one-month visit there will be a close-out discussion about the study. In addition to collecting step data at clinic visits, investigators will also measure patients' visual field tests, optical coherence tomography angiography (angio-OCT), and intraocular pressure (IOP) using Goldmann Tonometry. The investigators' hypothesis is that using an Official WeChat Patient Group will be a robust and effective stimulus to increase physical exercise.

Study Groups

Intervention Group

The intervention group will be enrolled into a WeChat Group to receive reminders to exercise and health education materials.

Group Type: EXPERIMENTAL

WeChat Group

Intervention Type: BEHAVIORAL

Consenting participants will be randomized to either the intervention or the control arm after successfully wearing an accelerometer for one week. The WeChat Group will be a community forum to share information, encourage each other, and receive communications from the study team. In addition, the study team will disseminate the following information through the group:

1. Daily/Weekly Reminders to exercise

2. Health education materials regarding glaucoma and general health and exercise

3. Motivational content

4. Surveys to gauge what information participants found most interesting and useful to help them exercise

Control Group

Controls will receive a handout telling them to increase walking and that walking may be helpful for the eye at the return visit.

Group Type: ACTIVE_COMPARATOR

Counselling

Intervention Type: BEHAVIORAL

Study participants in the control group will receive a handout telling them to increase walking and will be counseled that walking may be helpful for the eye at the return visit
