- A Hong Kong–specific algorithm with good discriminatory and calibration powers was developed to identify individuals with diabetes who have a high risk of sight-threatening diabetic retinopathy (STDR), compared with individuals with diabetes who have a lower risk of STDR.
- Overall, the use of a risk-based interval is safe; it can prevent blindness, increase the preservation of sight years relative to annual screening, and reduce the frequency of screening among individuals with diabetes who have a lower risk of STDR.
