Editor,—Biomicroscopic evaluation of the Cloquet’s canal is difficult in a normal eye. Although Goldmann, based on his extensive biomicroscopic studies,1 described as early as 1954 the detailed biomicroscopic anatomy of it, normally only parts of the Cloquet’s canal are available for direct biomicroscopic observation.

In this report I present a case in which not only the entire course of the Cloquet’s canal became visible by a marked cellular infiltration of the vitreous, but the cell infiltration itself dramatically improved the visibility of fine structures of the surrounding vitreous.
