Table 2
Relation between amount of visual field loss in both eyes and perception of VALDA in patients with visual acuity better than or equal to 20/40 in both eyes
| Visual field
in both eyes |
No of patients (n=127) | % Of patients referring VALDA (n=35) |
|---|---|---|
| (N, N) | 37 | 2.7% |
| (N,+) | 12 | 8.3% |
| (+,+) | 26 | 23.0% |
| (N,++) | 5 | 25.0% |
| (+,++) | 23 | 39.1% |
| (++,++) | 7 | 50.0% |
| (+,+++) | 11 | 63.6% |
| (++,+++) | 6 | 100% |

↵Visual field loss was separated into four groups by mean deviation (MD); (1) N = normal (MD = <2.6 dB); (2) + = 2.6 dB<MD = <9.5 dB; (3) ++ = 9.5 dB<MD = <18.5 dB; and (4) +++ = MD >18.5 dB.
