Macular and Peripapillary Retinal Capillary Measurement by OCT Angiography at Baseline, 12 Months, and 24 Months after Plaque Brachytherapy

	All Patients (n = 21)	No Radiation Retinopathy at 24 Months (n = 10)	Radiation Retinopathy at 24 Months (n = 11)
mSVC_VD (% area)
Baseline	48.4±3.6	48.1±4.1	49.0±4.0
12 mos	43.5±5.9 (P = 0.01)	46.8±3.3 (P = 0.232)	40.3±6.1 (P = 0.002)
24 mos	37.4±9.1 (P < 0.001)	42.4±5.1 (P = 0.02)	32.5±9.7 (P = 0.002)
FAZ area (mm²)
Baseline	0.26±0.11	0.26±0.09	0.26±0.12
12 mos	0.35±0.22 (P = 0.009)	0.27±0.08 (P = 0.375)	0.42±0.27 (P = 0.10)
24 mos	0.81±1.03 (P = 0.001)	0.30±0.10 (P = 0.426)	1.33±1.29 (P = 0.004)
NFLP_CD (% area)
Baseline	48.4±4.1	49.5±4.2	47.3±4.1
12 mos	46.7±5.0 (P = 0.04)	47.4±3.8 (P = 0.131)	46.0±6.1 (P = 0.275)
24 mos	44.5±6.1 (P < 0.001)	46.9±4.6 (P = 0.04)	41.7±6.7 (P = 0.008)

FAZ = foveal avascular zone; mSVC_VD = macular superficial vascular complex vessel density; NFLP_CD = peripapillary nerve fiber layer capillary density.

P< 0.05 was used to define significance.
