Term ID:
500052
Name:
Retinopathy of prematurity stage 3
Synonym:
ROP stage 3
Definition:
The neovascularization accumulates at the edge of the vascularized retina and extends into the vitreous (also called extra retinal fibrosis proliferation). In cases of Zone 2 and Zone 3, this may be sausage shaped. In more posterior Zone 1 disease, the stage 3 can appear as a direct extension of the normal retinal vessels but extending tangentially over the avascular retina.
