Study summary

The goal of this study is to quantify the improvement in completed ophthalmology referrals and quantify the number of children identified and treated for amblyopia or pre amblyopic strabismus resulting from the implementation of a new referral and tracking system.

Read the detailed description

Children who fail instrument vision screens at Dartmouth Hitchcock (D-H) Community Group Practice (CGP) Pediatric Clinics will be scheduled at a community vision specialist office before departure from the Pediatric clinic. If the patient does not attend the appointment (a no show) at the vision specialist office , this will be tracked and the patient will be rescheduled.
