title: Tritan pedigree without optic-nerve atrophy.
abstract: Results of several previous reports have questioned the occurrence of the tritan color deficiency independently of dominantly inherited optic atrophy. This report describes the results of testing 34 members of a pedigree (including four tritans) for whom optic atrophy can be ruled out according to criteria previously described by Krill et al.
