The Diagnostic Accuracy of Optical Coherence Tomography Angiography for Neovascular Age-Related Macular Degeneration: A Comparison with Fundus Fluorescein Angiography
Optical coherence tomography angiography (OCTA) of treated choroidal neovascularization. (a) A -mm OCTA en face projection image from an 84-year-old man who was treated with 20 intravitreal anti-VEGF injections. Note the large diameter of the trunk vessels (red arrow). At the periphery there appears to be a defined anastomotic connection around the border (blue arrows). (b) A -mm En face angiogram of the neovascular membrane from a 65-year-old man who were previously treated with 18 intravitreal anti-VEGF injections showing the red dashed circle that encompasses the trunk vessels of the lesion. Note the neovascular complex with vessels radiating in all directions from the center and the terminal loops of the vessels (blue arrows). (c) A -mm OCTA en face projection image from a 65-year-old man who were treated with 16 intravitreal anti-VEGF injections. Note the long extent of the vessels as they reach the edge of the lesion (red arrows).
