[A good course of retinopathy of prematurity in an infant weighting 398 g at birth].

BACKGROUND

Recently neonatal mortality of ELBW infants has improved remarkably, but the difficulty in preventing severe retinopathy of prematurity(ROP) or blindness implies that fundamental causes are still not resolved.

CASE: We encountered a case of ROP with a very good natural course in a very low birth weight(398 g) infant.

CONCLUSION

This case suggests the possibility of predicting the course of ROP in extremely low birth weight(ELBW) infants weighing less than 500 g, and of improving their management.
