Stevie Wonder has been blind since shortly after birth. The cause of his blindness is retinopathy of prematurity (ROP), a condition that can occur in premature babies who are born before their retinas are fully developed. ROP can cause the blood vessels in the retina to grow abnormally, leading to scarring and detachment of the retina. In severe cases, ROP can lead to blindness.
