An author's error occurred in the editorial in the December issue of the BJO (1997;81:1025). in the fourth paragraph, line 9, in the sentence that states "The definitive surgical treatment seems to be a combination of ipsilaterial inferior rectusstrengthening, ipsilateral superior rectus weakening, and contralateral inferior oblique weakening, all muscles adjustable sutures", the muscle specified should be inferior rectus. The author apologises for any confusion caused.
