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 | 0.005a | 0.016a | Infranasal | 24/0 | 36/24 | <0.001b | <0.001b | Supratemporal | 16/7 | 32/25 | 0.162b | 0.390b | Infratemporal | 16/7 | 24/38 | 0.014b | 0.012b |
| Retinal plexus | Supranasal | 20/3 | 48/13 | 0.406b | 0.541a | Infranasal | 20/3 | 36/24 | 0.019b | 0.024b | Supratemporal | 16/7 | 28/32 | 0.056b | 0.080b | Infratemporal | 16/6 | 32/30 | 0.162b | 0.063b |
