More than half of childhood blindness has a treatable cause
A new study conducted by the IRIS Registry found that more than half of children who are blind in the United States have a treatable cause of blindness.
In this cross-sectional study, 961 children were identified as having visual acuity 20/200 or worse in their better seeing eye.
The leading causes of blindness were as follows:
-Retinopathy of prematurity in 31.3%
-Nystagmus is 8.1%
-Cataract in 6.7%
Retina, optic nerve, and lens were the leading anatomic site in 47.7%, 11.6%, and 10%, respectively.
Overall, 52.4% of patients had treatable causes of blindness.
