A RAPID proliferative form of stage 3 retinopathy of prematurity (ROP)
located in zone I, as defined by the Committee for the Classification of Retinopathy
of Prematurity,1 developed in an infant
girl born at 23 weeks' gestation with a birth weight of 471 g. This aggressive
form of ROP does not develop according to the architecture described by the
committee, but as a flat, lacy network of extraretinal fibrovascular proliferation
from the advancing vascularized retina.2 The
infant underwent successful bilateral peripheral retinal photocoagulation
with a diode laser at 34 weeks' postconception age.
