Abstract

A quantitative method to analyze phase-resolved, raw backscatter echo data or the envelope of phase-resolved, raw backscatter echo data to characterize vitreous inhomogeneities as they relate to normal aging and vitreo-retinal disease. The technique can be applied to 2D or 3D data acquired from the vitreous. The approach provides an objective end value to characterize the vitreous and provide a tool for early diagnosis, monitoring and planning treatment of vitreo-retinal diseases.
