Validation of New Glaucoma Diagnostic and Progression Prediction Method

Project Summary

The proposed Temporal Speckle Analysis (TSA-OCT), which monitors the morphology and potentially a function of individual RGC (somas and axons), is very innovative. Proposed studies in animal models will allow its first-ever "Ground truth" validation against in vivo fluorescence SLO (FSLO) and the ex vivo images of the same retinas. Additionally, testing the predictive value of changes in individual RGCs scattering in animal models of glaucoma is also innovative. It will allow the first-ever evaluation of TSA-OCT as a potential clinical biomarker of glaucoma and its progression. Once the study is completed, there are several foreseeable benefits to the general public. First, this result will facilitate the implementation of TSA-OCT as a new biomarker in clinical glaucoma diagnostic, allowing earlier detection and better monitoring of treatment in individual patients. Second, its application to preclinical studies of novel glaucoma treatments will allow reduction of total animals needed for testing, considerably speeding up the validation period and shortening the time before new treatments become available to the general population.
