Investigating developmental retina vascular diseases

Developmental retina vascular diseases (DRVD) are a leading cause of childhood blindness in developed countries and an emerging problem in developing nations.

Molecular and phenotypic associations between familial exudative vitreoretinopathy (FEVR), a hereditary DRVD, and the more common non-hereditary retinopathy of prematurity (ROP) strongly suggest that elucidating the mechanisms that guide retina vascular development can guide the development of effective therapies for this group of conditions.

Using a model that starts with patients and ends with patients, our multi-disciplinary team of researchers aims to:

  • identify the genes that cause FEVR and other related conditions
  • study the role of the proteins encoded by these genes
  • use genetic models to find new treatments that will prevent childhood blindness
