A preterm baby of 26 weeks of gestation is born. At what age should screening for Retinopathy of Prematurity (ROP) be done
**Core Concept**
Retinopathy of Prematurity (ROP) is a disease of the eye affecting prematurely born babies, characterized by abnormal growth of retinal blood vessels. The risk of ROP is inversely related to gestational age and birth weight. **Premature infants**, especially those born before 31 weeks of gestation, are at higher risk.
**Why the Correct Answer is Right**
The American Academy of Pediatrics recommends screening for ROP in preterm infants with a birth weight of less than 1500 grams or gestational age of 30 weeks or less. The initial screening examination for ROP should be performed at 31 weeks' postmenstrual age or 4 weeks of chronological age, whichever is later. For a baby born at 26 weeks, the screening should be done at 31 weeks postmenstrual age.
**Why Each Wrong Option is Incorrect**
**Option A:** This option would be too early for the screening.
**Option B:** This option might not be specific enough for the condition.
**Option D:** This option would be too late, potentially missing the critical period for intervention.
**Clinical Pearl / High-Yield Fact**
Remember, the key to managing ROP is early detection and treatment. Regular screenings are crucial for preterm babies at risk.
**Correct Answer:** D. 31 weeks postmenstrual age or 4-6 weeks of age, whichever is later
