Levels of prevention
(diabetic retinopathy)
• Primary prevention:
– Health promotion
Balance diet, exercise (healthy life)
– Specific protection:
For high risk : low GI diet, exercise
• Secondary Prevention
– Early diagnosis & prompt treatment:
- DM screening
- Adequate and continuing treatment
- Avoid complication:
(microvascular, macrovascular) through
maintenance normal blood sugar
to avoid hyperglycemia or hypoglycemia
DM diet
• Tertiary prevention
- Disability limitation
Prevent from blindness caused by
diabetic retinopathy through DM control
- Rehabilitation: to save and rehabilitated
