Measured Outcome Parameters for Each Cohort of Rats
| Group, Mean (95% CI) | ||||
|---|---|---|---|---|
| Parameter | Young Sham(n = 5) | Young OVX(n = 6) | Middle-Aged Sham(n = 6) | Middle-Aged OVX(n = 5) |
| Outflow facility (nl/min/mm Hg) | 21.2 (11.2 to 40.0) | 12.9 (8.7 to 19.0) | 26.1(23.8 to 28.7) | 19.7 (12.7 to 30.4) |
| β (unitless) | −0.38 (−0.49 to 0.25) | −0.39 (−0.75 to 0.19) | −0.55 (−0.65 to 0.46) | −0.54 (−0.62 to 0.46) |
| Ocular compliance (nl/mm Hg) | 109 (96 to 123) | 131 (111 to 154) | 97 (85 to 111) | 111 (95 to 130) |
| γ (mm Hg) | −8.1 (−11.6 to 4.8) | −6.3 (−9.5 to 3.2) | −5.6 (−7.5 to 3.7) | −6.1 (−9.9 to 2.3) |
The outflow facility at a reference pressure of 15 mm Hg (Cr) and the corresponding nonlinearity parameter (β) describe the outflow facility–pressure relationship. Ocular compliance at a reference pressure of 20 mm Hg (ϕr) and the corresponding nonlinearity parameter (γ) describe the ocular compliance–pressure relationship. Because β and γ take negative values, we report means and confidence intervals.
