Unfortunately, the acknowledgments were omitted from the paper by Hope, Bundey, Proops, and Fielder, which appeared in the January issue (BJO 1997;81:46–53). They read as follows:

This study was generously supported by the British Retinitis Pigmentosa Society and by the Birmingham Eye Foundation. The authors thank Peter Good, neurophysiologist, for carrying out vision function tests at the BMEH, Stuart Burrell and Mary Mills, audiologists, and John Werning, otolaryngology fellow, for undertaking audiovestibular evaluations.

We apologise for this omission.
