John Crabb Laboratory

Research

Goals and Projects

• The long-term goal of our uveal melanoma project is the development of a multi-antibody immunological assay for UM metastasis that will complement current cytogenetic and genetic prognostic methods and establish for the first time methods to detect and quantify circulating uveal melanoma tumor cells.
• The long-term goals of our glaucoma projects are to better understand the molecular mechanisms of glaucomatous vision loss, identify therapeutic targets and develop a panel of blood-borne glaucoma biomarkers.
• The long-term goal of our age-related macular degeneration (AMD) project is the development of molecular technology for assessing AMD risk and monitoring AMD therapeutics.
