Distribution of nine-month grating acuity outcomes among randomized eyes by treatment assignment*
| Outcome | Eyes treated at high-risk prethreshold (n = 336) | Conventionally managed eyes (n = 328) | ||
|---|---|---|---|---|
| Favorable | ||||
| Normal (≥3.70 cycles per degree) | 219 | (65.2) | 203 | (61.9) |
| Below normal (1.85 to <3.70 cycles per degree) | 69 | (20.5) | 60 | (18.3) |
| Unfavorable | ||||
| Poor (measurable but <1.85 cycles per degree) | 15 | (4.5) | 18 | (5.5) |
| Blind/LV (NLP, LP only, LV card only) | 33 | (9.8) | 47 | (14.3) |
| Total | 336 | (100) | 328 | (100) |
LP, light perception; LV, low vision; NLP, no light perception.
