| Prominent venous drainage flowa | 52.0% (51/98) | 94.7% (36/38) | 54.0 (11.6–251.7) | <.001 |
| Anterior | 36.7% (36/98) | 78.9% (30/38) | 33.8 (10.7–106.5) | <.001 |
| Lateral | 22.4% (22/98) | 34.2% (13/38) | 3.0 (1.1–7.8) | .030 |
| Posterior | 23.5% (23/98) | 47.4% (18/38) | 9.9 (3.3–30.2) | <.001 |
| Orbital/periorbital soft tissue swelling | 39.8% (39/98) | 84.2% (32/38) | 40.4 (12.5–130.8) | <.001 |
↵a Prominent venous drainage flow indicates the presence of prominent venous drainage flow in at least 1 of the anterior, lateral, and posterior prominent venous drainage flows.
