Neovascular age-related macular degeneration (AMD), characterized by the presence of choroidal neovascularization (CNV), accounts for the majority of AMD-related vision loss. Optical coherence tomography (OCT) has become the most frequently used test for AMD evaluation; however, fluorescein angiography (FA), which requires an invasive intravenous dye injection, is needed for initial CNV diagnosis. Using a high-speed OCT system, we have developed an algorithm called “split-spectrum amplitude decorrelation angiography” (SSADA) to non-invasively image and measure both retinal and choroidal blood flow. Preliminary results showed that OCT angiography successfully imaged CNV tissue. The goal of the proposed project is to improve OCT angiography technology and determine its role in AMD evaluation and management.
