Age related macular degeneration

At a late stage in the publication process we inadvertently introduced an authorship error into this editorial by Neil M Bressler (9 December, pp 1425-7). The published article was attributed to two authors—Professor Bressler and a Professor James P Gills. In fact, Professor Bressler is the sole author, and he is the James P Gills professor of ophthalmology. We apologise for the confusion.
