Prediction of visual morbidity from perinatal data
| Visual impairment | Perinatal factor | Odds ratio (95% CI) | P value |
|---|---|---|---|
| Visual acuity <6/9 | |||
| at 6 m | Birthweight (kg) | −20.1 (−1.8 to −221.4) | 0.014 |
| at 0.3 m | No predictive variables | ||
| Poor contrast sensitivity (at any spatial frequency) | Birthweight (kg) | −6.7 (−1.1 to −40.4) | 0.035 |
| Myopia | Birthweight (kg) | −99 (−3.3 to −2980) | 0.007 |
| SGA | 5.4 (1.3 to 22.8) | 0.02 | |
| IVH | 4.6 (1.1 to 19.3) | 0.03 | |
| Hypermetropia | No predictive variables | ||
| Squint | IVH | 5.1 (1.2 to 21.5) | 0.02 |
| Absent stereopsis | Apgar score (1 minute) | −1.3 (−1.1 to −1.16) | 0.003 |
-
SGA: Small for gestational age; IVH: intraventricular haemorrhage.
