OCT angiography quantitates differences in lesion responses to anti-VEGF therapy
COLORADO SPRINGS, Colo. — Type 1 neovascular lesions are large, mature and resistant to anti-VEGF therapy, whereas type 3 lesions are small capillary tufts that are highly responsive to just one anti-VEGF injection, according to a study presented here.Using OCT angiography, David Sarraf, MD, and colleagues looked at the quantitative and qualitative effects of anti-VEGF therapy in both types of lesions in cases of age-related macular degeneration.
