At Childrens Hospital Los Angeles (CHLA), a national survey is being performed to examine the distribution of optic nerve hypoplasia/septo-optic dysplasia (ONH/SOD) cases across the United States. Mark Borchert, M.D., is conducting this research with Pamela Garcia-Filion, MPH, who is a Ph.D. student in Epidemiology at the University of Southern California.

The researchers are asking for your assistance in providing this survey to families that have a child with ONH/SOD. The survey takes less than 15 minutes to complete and participation is voluntary. The Institutional Review Board at CHLA has approved the researchers to collect information from the parents about the:

  1. season and year their child with ONH was born,
  2. census tract for where the mother lived 3 months before conception,
  3. census tract for where the mother lived during the 1st trimester, and
  4. census tract for where the mother lived during the 2nd trimester of the pregnancy.

The survey can be submitted to us by mail or it can be completed over the Internet at any one of the following websites:

If you do not want to complete the survey over the Internet, then you can complete a paper version of the survey provided and return it to us by mail. Our address is:
