The purpose of this study is to evaluate the safety and efficacy of both BETAXON and AZOPT in pediatric patients. Patients will dose with study drug at 8 am and 8 pm daily for twelve weeks. Patients will have vision tested, slit lamp exam, blood pressure and pulse checks at each visit. Patients will have a dilated fundus exam and corneal measurements taken at first and last visit.
