To the Editor.  —The subject of efferent innervation of primate retinas has been a controversial topic. With full realization of this fact, it was not our intention to claim priority or to "rediscover" centrifugal nerve fibers in human retinas. With all deference to Dr. Wolter, we acknowledge that he was the first investigator to document any morphologic evidence for the possible presence of efferent nerve fibers in human retinas. However, his claim that he has been able "to demonstrate conclusively the intraretinal course and pattern which this type of centrifugal nerve fibers take prior to their termination" in humans may be an exaggeration.Figure 13 referred to by Dr. Wolter (Amer J Ophthal51:1123 [May] 1961) is a flat frozen section stained by Del Rio-Hortega's method. When frozen sections of the retina made, the dimension of the specimen, from which the section is cut, does not encompass the entire
