After publication of this article [1] it came to our attention that Table 1 was presented incorrectly. The correct table can be found below:
Table 1.
Aberrations (in microns) and dry eye evaluation data compared between migraine (Group 1) and controls (Group 2) using independent sample t- test
| Parameter | Group 1 (Mean ± SD) (N = 60) |
Group 2 (Mean ± SD) (N = 60) |
P value |
|---|---|---|---|
| Total aberrations (RMS) | 1.20 ± 0.66 | 1.01 ± 0.34 | 0.049* |
| Higher order aberrations (RMS) | 0.47 ± 0.03 | 0.38 ± 0.12 | 0.009* |
| Coma (RMS) | 0.25 ± 0.13 | 0.20 ± 0.11 | 0.030* |
| Trefoil (RMS) | 0.26 ± 0.16 | 0.23 ± 0.13 | 0.260 |
| Spherical aberration (RMS) | 0.16 ± 0.20 | 0.10 ± 0.06 | 0.018* |
| Lipiview ICU | 63.18 ± 2.67 | 69.76 ± 5.20 | <0.001* |
| OSI | 1.26 ± 0.02 | 0.921 ± 0.14 | <0.001* |
| TBUT (seconds) | 9.41 ± 1.71 | 9.66 ± 1.51 | 0.398 |
RMS = Root Mean Square; ICU = Interferometric Coloric Units; OSI = Ocular Scatter Index; TBUT = Tear film break up time
N: sample size
*indicates a statistically significant difference between the two groups. A p value < 0.05 was considered statistical significant
