Brief Summary

Diabetic retinopathy affects over one third of all people with diabetes and is one of the leading causes of vision loss. The management of diabetes and its complications should include screening for diabetic retinopathy. A randomised trial is therefore needed of the use of a simple and widely practicable approach to explore the integration of eye care in managing diabetes. The trial is designed as a randomised, controlled, superiority trial. The aim is to explore the effectiveness of ophthalmologist-delivered health education on top of routine community care on blood glucose and eye-related clinical outcomes in type 2 diabetic patients at risk for diabetic retinopathy.

Intervention group

EXPERIMENTAL
Other: Ophthalmologist-delivered health education

Control group

OTHER
Other: Usual care

Interventions

The educational intervention will be conducted on-site by a qualified, experienced ophthalmologist at an ophthalmic center with goals of building awareness on diabetes symptoms, particularly on diabetic retinopathy, and its risk factors with appropriate management.

Intervention group

Usual care follows standard procedure on diabetes management similar to the routine service provision.

Control group
