Obstructive MGD | Seborrhoeic MGD | Normal controls | |
Schirmer test (mm) | 5.4 (2.1) | 6.4 (2.3) | 8.5 (3.2) |
Cotton thread test (mm) | 10.4 (4.3) | 12.7 (4.9) | 13.7 (3.1) |
Tear film BUT (s) | 4.4 (1.7) | 4.9 (2.1) | 7.9 (1.9) |
Fluorescein score | 1.7 (1.5) | 0.9 (1.1) | 0 |
Rose bengal score | 0.5 (0.7) | 0.5 (0.6) | 0.1 (0.3) |
Tear lipocalin (mg/ml) | 0.89 (0.19)* | 1.05 (0.22)** | 1.54 (0.23) |
Total protein (mg/ml) | 8.66 (1.50) | 9.16 (1.76) | 9.48 (1.72) |
MCD, meibomian gland dysfunction.
The concentration of lipocalin in patients with obstructive MGD and seborrhoeic MGD was significantly lower than that of normal controls (*p = 0.00021 and **p = 0.00042, respectively).
