Quantitative OCT angiography findings according to pattern classification of type 1 neovascularization exudative age-related macular degeneration.

After pattern classification, type 1 NV patterns with fine branching vessels were considered to have exudative activity compared to NV without fine branching. The quantitative analysis of type 1 NV according to patterns showed the presence of peripheral tiny branching vessels was associated with NV activity.
