Retinopathy of prematurity (ROP) screening criteria in India per NNF guidelines include examination of all preterm infants with gestational age ≤34 weeks OR birth weight ≤2000 g. The screening should begin at:
- A 2 weeks after birth regardless of gestational age
- B 3 weeks after birth for all screened infants
- C 32 weeks postmenstrual age (PMA) or 4 weeks after birth, whichever is later ✓
- D At discharge from NICU
Correct answer: C. 32 weeks postmenstrual age (PMA) or 4 weeks after birth, whichever is later
Explanation
Indian NNF (National Neonatology Forum) guidelines recommend ROP screening beginning at 32 weeks postmenstrual age (PMA) or 4 weeks after birth, whichever is later. This timing is selected because ROP develops from approximately 32–34 weeks PMA as retinal vascularization reaches the periphery. Starting at the absolute maximum of 4 weeks after birth ensures no case is missed in very premature infants. Follow-up intervals depend on findings: zone I requires weekly examination.
