Cerebral Visual Impairment

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).

Restorative visual rehabilitation is frequently used to enhance the visual development and function of children with low vision. An important strategy within this field is visual stimulation, which is particularly used for infants and toddlers with low vision, as well as for children who have both developmental disabilities and low vision.This study has two primary objectives.The first objective is to examine the effect of using intensive, specific, and flickering black-and-white checkerboard patterns to enhance visual function in children with mild to moderate low vision. The second objective is to develop a visual stimulation program tailored for children with severe or profound multiple disabilities and visual impairments, and to evaluate its effectiveness.
