Variables recorded at baseline and at 3 and 12 months of follow up in patients with obstructive sleep apnea undergoing continuous positive airway pressure treatment.
| Baseline | 3 Months | 12 Months | P* Raw | P** Adjusted (1) (2) (3) |
|
|---|---|---|---|---|---|
| IOP (mmHg) | 14.65 (±3.27) | 14.13 (±2.41) | 15.27 (±2.93) | 0.039 | 0.241 0.231 0.001 |
| LogMAR | −0.04 (±0.08) | −0.06 (±0.09) | −0.07 (±0.08) | 0.121 | NA |
| VFI (%) | 98.13 (±2.21) | 97.81 (±2.44) | 98.38 (±1.76) | 0.499 | NA |
| VF MD (decibels) | −2.20 (±1.24) | −2.16 (±1.23) | −2.10 (±1.04) | 0.472 | NA |
Data expressed as the mean (±standard deviation). P* raw: significance level obtained through the Friedman test. P** adjusted: significance level adjusted through the Wilcoxon test as a post-hoc test for multiple comparisons. (1) Baseline vs. 3 months. (2) Baseline vs. 12 months. (3) 3 months vs. 12 months. NA: Post-hoc test not applicable for a P* greater than 0.1. Values in bold indicate p < 0.05. IOP = intraocular pressure, LogMAR = logarithm of the minimum angle of resolution, VFI = visual field index, VF MD = visual field mean deviation.
