Table 3. Fluctuations in Corneal Thickness (CT) in µm from baseline to 30min after eye rubbing in allergic subjects [mean age (standard deviation, SD) = 22.9(0.8)y]. Values expressed as mean (standard deviation, SD), of values.
| Time (min) | Central | Inferior | Superior | Temporal | Nasal |
| Baseline | 527.6(37.1) | 577.9 (30.7) | 623.3(37.6) | 578.6(34.0) | 621.2(26.2) |
| 0 | 525.9(34.9) | 572.2(32.9) | 618.3(41.8) | 562.7(39.1) | 619.6 (37.9) |
| 5 | 526.8(33.5) | 573.9(32.9) | 621.1 (33.2) | 578.2(38.3) | 620.3 (31.8) |
| 10 | 529.4(32.5) | 574.8(29.4) | 613.5(45.5) | 580.8(32.9) | 620.8(34.9) |
| 20 | 526.0(44.4) | 575.3(31.4) | 632.2(32.0) | 577.5(28.9) | 614.1 (37.7) |
| 30 | 531. 9(30.3) | 579.4(31.9) | 620.4(36.7) | 580.8 (31.4) | 616.8(31.8) |
| P | 0.33 | 0.16 | 0.24 | 0.85 | 0.59 |
P values are results of Repeated Measures Analysis of Variance (RM-ANOVA) conducted on for example baseline TCT versus TCT at 0, 5, 10, 20 and 30min post-habitual eye rubbing. P<0.05 is considered significant.
