About five years ago, a report of a typical posterior lenticonus which I had studied with the slit-lamp was published in the Archives of Ophthalmology,1 with an analysis of four similar reports, one by Vogt, two by Riedl and one by Whiting, all that had appeared at that time.2 Since then, through the courtesy of Drs. H. H. Tyson and J. Ziporkes, of New York, I have been able to observe two other cases with the slit-lamp, and over twenty slit-lamp studies have been reported under this title. Moreover, in this interval the knowledge of the normal and abnormal lens and neighboring structures has been advanced by many slit-lamp workers and others, so that the time seems opportune for a review of the whole subject of lenticonus posterior.
The number of cases published in the past six years—about half as many as in the previous thirty-five—has raised
