Children with amblyopia, hydrocephalus and born prematurely (IRB# 22229EP)

Status: Completed



  • Joel M. Weinstein, M.D. (retired)
  • Marianne Boltz, O.D.



Penn State Hershey Eye Center's Joel Weinstein, M.D.(retired), and Marianne Boltz, O.D., are trying to develop an objective test that can be used to accurately measure vision in children of all ages, including those who are not able to read and speak.

Children are needed to participate in this research study of cerebral visual impairment in children. This study uses brain wave recordings to measure vision, does not involve any medications, or cause any significant discomfort.

Children aged five to seventeen who were born prematurely (before 32 weeks gestation) or who have been treated for hydrocephalus and who can identify simple pictures used to measure vision are eligible to participate.

Compensation is provided for participation.
