Clinical Trial 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.

Eligibility

Inclusion Criteria:

• Glaucoma diagnosis

• Age 40 years and above

• Ability to sign informed consent

• Ability to use WeChat

Exclusion Criteria:

• Patients with severe heart, lung, or kidney disease which may prevent them from exercising

• Patients who self-report walking 12,000 steps or more per day

Related Conditions & MeSH terms

• Glaucoma

Intervention

Behavioral:
• WeChat Group
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: Daily/Weekly Reminders to exercise Health education materials regarding glaucoma and general health and exercise Motivational content Surveys to gauge what information participants found most interesting and useful to help them exercise
• Counselling
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

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Efficacy of using WeChat as an intervention to increase physical activity in Chinese glaucoma patients	The primary outcome variable will be the number of daily steps taken over the course of one month for each participant. This outcome will be measured by having participants wear the Accelerometer WGT3X-BT, from which we can collect steps data. From this primary outcome measure we will also assess the change in number of steps taken comparing the first week to the following month after the intervention.; Assuming mean enrollment number of steps per day is 9,302.29, we can detect an average increase of 2,500 steps per day with alpha set to 0.05 with 80% power.	5 weeks
Secondary	Time spent in moderate to vigorous physical activity	We will also analyze the time spent in moderate to vigorous physical activity.	5 weeks
