Average amount of visual acuity deterioration(SE) and average amount of overall improvement in visual acuity (SE) in the two groups at the long term follow up examination in logMAR values
| Anisometropia | Average deterioration in visual acuity (SE) | Average overall improvement in visual acuity (SE) |
|---|---|---|
| ⩽1.50 D | −0.08 (0.02) | 0.55 (0.04) |
| ⩾1.75 D | −0.28 (0.10) | 0.33 (0.14) |
| p<0.021 | p<0.031 |
↵Deterioration is defined as the difference between the visual acuity score at the long term follow up examination and at the end of treatment, and overall improvement is defined as the difference between the visual acuity score at the long term follow up examination and at the commencement of treatment.
