The screening strategy for prevention of blindness from diabetic retinopathy according to the NPCB involves:
Show Hint
Retinopathy only affects diabetics, so you screen only the at risk group.
Updated On: Jun 24, 2026
- Opportunistic screening
- High risk screening
- Mass screening
- Screening by primary care physician
Show Solution
The Correct Option is B
Solution and Explanation
The key idea is to match the screening method to who is actually at risk. Diabetic retinopathy can only develop in someone who already carries diabetes, so the NPCB targets that defined risk group rather than the whole community. Examining only diabetics for early retinal damage is the definition of high risk screening, and it concentrates limited eye care resources where disease will appear. Mass screening of every citizen wastes effort on people with no chance of retinopathy. Opportunistic screening picks up whoever happens to walk in for another complaint and is unreliable for systematic prevention. Leaving the job to a primary care physician alone ignores the need for proper fundus evaluation. Therefore the programme uses targeted high risk screening of diabetics. $$\boxed{\text{High risk screening}}$$
