Hyperdeviation in Subjects with SO Palsy
| Hyperdeviation in Upright Position | BHTP | Unilateral BHTD | |
|---|---|---|---|
| Atrophy (n = 8) | 13.1 ± 3.7 | 20.1 ± 5.5 | 7.0 ± 4.5 |
| Nonatrophy (n = 9) | 7.6 ± 5.0 | 10.3 ± 5.6 | 2.7 ± 2.4 |
| P | 0.02 | 0.003 | 0.02 |
Mean ± SD (degrees). Unilateral BHTD, unilateral Bielschowsky head tilt difference (difference in hypertropia between ipsilesional head tilt and upright head position). Statistical analysis comparing groups with versus without atrophy was performed by Student’s t-test.
