Kids' vision trouble seeing the blackboard may be part of a problem that goes beyond kids' learning difficulties; it may trigger discipline problems, too. According to the American Optometric Association, one in four school age children have a vision problem, yet just a third of school-agers have ever had an eye exam. In addition, a study found that over 70 % of juvenile offenders have untreated vision problems. In fact, the AOA says nearly all learning from kindergarten through high school is vision based.
A treatment that can be done like an insulin shot is being tested to curb harmful blood vessel growth in the eye. Researchers at Johns Hopkins are studying a way to control VEGF, a substance the body naturally releases to grow new blood vessels. Scientists have modified VEGF, turning it into a sponge of sorts that halts the growth of new blood vessels. The unchecked growth of new, and often leaky, eye blood vessels is often the cause in diabetic retinopathy and wet macular degeneration.
