The authors sent questionnaires to ophthalmologists requesting information concerning their personal experience. These contributors of data were distributed throughout the United States. They supplied the medical records of patients they had clinically judged to have uveal melanomas requiring therapy and on whom certain minimal liver-function studies had been made preoperatively. We believe that retrospective studies of this type are almost certainly going to be biased by the selection of
