Relative contribution of VRIA to each category of visual impairment
| Visual impairment category | Monocular visual impairment, n (%*) | Binocular visual impairment-better seeing eye, n (%*) | Binocular visual impairment-worse seeing eye, n (%*) |
| Mild (LogMAR >0.3–<0.45) | 29 (3.2) | 10 (3.8) | 2 (2.4) |
| Moderate (LogMAR 0.45–<1.0) | 29 (4.2) | 2 (1.5) | 12 (4.1) |
| Severe (LogMAR 1.0–<1.3) | 2 (2.3) | 0 | 2 (8.0) |
| Blindness (LogMAR >1.3) | 0 | 0 | 1 (16.7) |
| Total | 60 | 12 | 17 |
