Children born prematurely may develop a characteristic retinal disease named retinopathy of prematurity (ROP). This disease could lead to retinal detachment and blindness. ROP was traditionally treated with laser, but injection with a medication (A-VEGF) has become more common. In this study, the researchers will explore whether treatment of ROP affects visual function and retinal development. To explore this, the study group will examine children with ROP (but not treated) with children treated with either laser or injection. The researchers will compare the children's visual functions (e.g. visual acuity and visual field) and their retinas (e.g. central and peripheral retina).
