Ophthalmology - Edward Chaum

Research Interests

The focus of the basic science research program in our laboratory is in five major areas:

  • Translational research in the development and application of gene therapy to the treatment of retina degenerative diseases,
  • Tissue engineering approaches to understanding and modulating the growth, aging and wound healing responses of ocular retinal pigment epithelial cells (RPE),
  • Molecular analyses of retinal pigment epithelial cell responses to oxidative stress,
  • Characterization of a newly discovered IGF binding protein regulatory system in the RPE, and
  • Tele-ophthalmology and automated diagnostics

Other areas of active research include collaborations on numerous pilot basic science and clinical projects with investigations into:

  • Genomic analysis of RPE gene expression,
  • The role of CD81 in proliferative vitreoretinopathy, wound healing and retinal detachment,
  • The role of Arf gene mutations in the developmental eye anomaly persistent fetal vasculature,
  • Electrochemical quantification of blood metabolites and drugs, and
  • Nanotechnology applications in retinal surgery, and
  • Clinical research studies.
