EDITOR—In their randomised controlled trial Clarke et al showed directly for the first time that treatment improves visual acuity, at least for moderate amblyopia.1
However, we take issue with the conclusion that vision of 6/12 in one eye and 6/9 in the other should not be treated. There are several possible reasons why no effect of treatment was found for this group.
