Current status of retrolental fibroplasia.

The improved survival of very premature infants is probably responsible for the moderate increase in incidence of RLF in the past few years. Because of the new cases of RLF, ophthalmologists should continue to focus their attention on this retinopathy of the premature infant. The pathogenesis of RLF and the role of oxygen, along with a brief discussion of newer concepts, are discussed.
