Pediatric Eye Disease Investigator Group (PEDIG)

General Information about the Pediatric Eye Disease Investigator Group (PEDIG)

The Pediatric Eye Disease Investigator Group (PEDIG) is a collaborative network dedicated to facilitating multicenter clinical research in strabismus, amblyopia and other eye disorders that affect children. The network, which was formed in 1997, is funded by the National Eye Institute (NEI). The NEI is a part of the National Institutes of Health, which is the branch of government that funds medical research. There are currently over 100 participating sites (offices) with over 300 pediatric ophthalmologists and pediatric optometrists in the United States, Canada and the United Kingdom participating in the network.

Five core centers within PEDIG support overall operation and leadership of the network. The core centers are:

  • The office of Network Chair (David K. Wallace, M.D., M.P.H., Duke University Eye Center, Durham, NC)
  • The office of the Past Network Chairs (Michael X. Repka, M.D., Wilmer Eye Institute, Baltimore, MD and Jonathan M. Holmes, M.D., Mayo Clinic, Rochester, MN)
  • The offices of the Network Vice-Chairs (S. Ayse Erzurum, M.D., Eye Care Associates, Poland, OH, and Angela M. Chen, O.D., M.S., Marshall B. Ketchum University Southern College of Optometry, Fullerton, CA)
