Average scleral strains at different pressure levels
| Strain | 15 mmHg | 25 mmHg | 35 mmHg | 45 mmHg | |
|---|---|---|---|---|---|
| Axial a | Meridian | −2.4 ± 0.8% | −3.4 ± 1.2% | −4.2 ± 1.2% | −5.1 ± 1.5% |
| Circum | −3.1 ± 1.6% | 4.1 ± 1.8% | 5.0 ± 1.9% | −5.9 ± 2.2% | |
| Lateral a | Meridian | 1.4 ± 0.6% | 1.8 ± 0.7% | 2.1 ± 0.6% | 2.2 ± 0.7% b |
| Circum | 1.1 ± 0.5% | 1.1 ± 0.5% | 1.2 ± 0.6% | 1.2 ± 0.6% b |
a
The axial strains were significantly greater than the lateral strains at all pressure levels, P < 0.01.
b
For lateral strains, the circumferential was significantly smaller than the meridian at 45 mmHg, P < 0.05.
