Changes of Peripapillary Capillary Density in Patients with Vogt–Koyanagi–Harada Disease Evaluated by Optical Coherence Tomography Angiography

Table 2

Changes of peripapillary capillary density after treatment in VKH patients with or without optic disc swelling.

		Optic disc swelling group (eye number of decreased capillary density/eye number of increased capillary density)	Nonoptic disc swelling group [eye number of decreased capillary density/eye number of increased capillary density]	value (the percentage of decreased vessel density)	value (the percentage of increased vessel density)
RPC	Supranasal	24/0	48/13	0.005^a	0.016^a
	Infranasal	24/0	36/24	<0.001^b	<0.001^b
	Supratemporal	16/7	32/25	0.162^b	0.390^b
	Infratemporal	16/7	24/38	0.014^b	0.012^b
Retinal plexus	Supranasal	20/3	48/13	0.406^b	0.541^a
