Table 5 Structural outcomes over time.

*Percentage of eyes with unfavourable structural outcome increased between 6 and 9 months. 4A detachments before vitrectomy or buckling surgery were classified as favourable at 6 months. If an eye with a retinal detachment grading 4A then had vitrectomy or buckling surgery, it was reclassified by the protocol as unfavourable at 9 months.

†Numbers differ slightly from published final results⁸ because one additional child that underwent a vitrectomy before 9 months of age was not reported until after the date of the publication.
