In Brief:
Quantitative analysis of the choriocapillaris flow using swept-source optical coherence tomography angiography shows that eyes presenting with Type 3 macular neovascularization present a decreased choriocapillaris perfusion compared with intermediate age-related macular degeneration eyes, with the percentage of flow deficits, total area, and average size of flow deficits greater than intermediate age-related macular degeneration eyes.
