title: Accuracy of referencing in the ophthalmic literature.
abstract: OBJECTIVE
  To investigate the frequency of citation and quotation errors in the ophthalmic literature.
  
  
  METHODS
  Analysis of 200 references from 100 papers published in 10 ophthalmic journals.
  
  
  METHODS
  A sample of 20 references was randomly selected from each of the 10 journals and each reference was checked for accuracy. Quotations were categorized as totally, partially, or not accurate.
  
  
  RESULTS
  There were 35 citation errors in 32 references, only four of which were errors in PubMed. Thirty quotations of references were not accurate; 20 were partially accurate.
  
  
  CONCLUSIONS
  Citation and quotation errors are relatively common within the ophthalmic literature. This may be improved through technical editing.
