Pupillary responses to light in a normal 30-week gestation infant are likely to be:

Explanation:
Pupillary light reflexes in preterm infants are present but not fully mature. At 30 weeks' gestation, the pathways that constrict the pupil are functional, but the parasympathetic control is immature, so the constriction occurs more slowly and with less briskness. The pupil will tighten in response to light, but the response is slower and less robust than in a term infant. That’s why the expected description is sluggish. An absent reflex would indicate more severe immaturity or neurologic injury, and a fully present, brisk reflex would be expected only as the infant matures further.
