Retina Diseases and Uveitis

Areas of Research Focus

Retina Injury Protection: Animal Models

  • Ischemic/reperfusion injury model
  • Light induced injury model

We have conducted basic science research in different animals to evaluate how to protect the retina with different chemical compounds from various injuries including genetic, light induced and vascular (blood flow impairment) injuries. This research can help develop new treatments that can help to treat various retinal diseases.

Age Related Macular Degeneration (AMD)

We have conducted basic science research in different animals to evaluate how to protect the retina with different chemical compounds from various injuries including genetic, light induced and vascular (blood flow impairment) injuries. This research can help develop new treatments that can help to treat various retinal diseases.
