Comparison of fluorescein angiographic findings in type 1 and type 2 retinopathy of prematurity with intravitreal bevacizumab monotherapy and spontaneous regression.

Peripheral vascular abnormalities probably occur as a result of ROP itself because similar FA findings were detected both in type 1 and type 2 ROP patients with or without treatment, although significantly less in IVB-treated group. Retinal vascularization usually reaches the farthermost limits with time even though it slows down in eyes treated with IVB, indicating the importance of a longer follow-up.
