Table 1.
Comparison of the mean dry-eye symptom scores of the dry-eye and non-dry-eye participants.
| Dry-eye symptom score | P | ||
|---|---|---|---|
| Normal situation | COVID-19 lockdown | ||
| Mean (SD) | Mean (SD) | ||
| Dry-eye participants | |||
| Total | 74.10 (14.55) | 72.16 (15.98) | < 0.001* |
| Age ≤ 60 years | 74.16 (13.94) | 71.96 (15.21) | < 0.001* |
| Age > 60 years | 73.79 (17.73) | 73.21 (19.88) | 0.639 |
| Non-dry-eye participants | |||
| Total | 86.00 (14.95) | 84.25 (16.70) | < 0.001* |
| Age ≤ 60 years | 85.9 (15.36) | 84.05 (17.18) | < 0.001* |
| Age > 60 years | 86.98 (10.15) | 86.23 (10.88) | 0.167 |
*P < 0.05; higher dry-eye symptom score indicates fewer dry-eye symptoms.
