Optical Coherence Tomography Angiography to Distinguish Changes of Choroidal Neovascularization after Anti-VEGF Therapy: Monthly Loading Dose versus Pro Re Nata Regimen

Table 1

Comparison of categorical variables between baseline and month 3 in groups A (treatment-naive patients undergoing monthly loading phase) and B (treated patients undergoing PRN regimen). Note that there is no statistically significant morphological change between baseline and month 3 (computed value) in either group.

	Feeder vessel	3	3	1	3
	Anastomotic arcade	1	1	0	1
	Dark halo	4	4	2	4
