Ronald P. Danis, Amitha Domalpally, Ellie Corkery, Ruth Shaw, Ashwini Narkar, Jim White Abstract Purpose: Given that baseline area and configuration of GA are associated with its progression rate, we hypothesized that a non circular configuration has a higher growth rate. Index of non circularity was developed on color photographs and was a strong predictor …
Jeong W. Pak, Amitha Domalpally, Dawn Myers, Xiufen Yang, Ashwini Narkar, Yijun Huang, and Ronald P. Danis Abstract Purpose: To characterize drusen morphology and retinal layer abnormalities by simple, ordinal description and to associate these features with drusen progression over one year on SD-OCT scans. Methods: Twenty two pairs of SD-OCT macular volume scans at …
