Zone I retinopathy of prematurity
W. Tasman
Two (5.4%) of 37 patients with retinopathy of prematurity were noted to
have zone I vascularization of the retina in at least one eye. Three eyes
in the two patients showed plus disease with nonflorid stage 3 ridge
formation and extraretinal fibrovascular proliferation. Two of the three
eyes were not treated and rapidly progressed to total retinal detachment
and blindness. The third eye was treated with cryotherapy and this was
followed by resolution of the plus disease. Although the treated eye did
not develop dragging of the retinal vessels or retinal detachment, it is
unfortunately blind.
