In a recent communication1 the results of a series of investigations were reported on the delineation of the retinal perivascular region in animals. The object of that report was to review previous methods by which various workers had attempted to inject the so-called retinal perivascular lymph spaces and to submit the results of other experiments that I had devised.
The conclusions of the work tended to show that when the modified Weed-Wegefarth-Mott technic was used, prussian blue particles could be demonstrated about the retinal vessels. Study of the report mentioned will reveal that the test solution was injected into the anterior vitreous in a great number of experimental animals, dogs and rabbits, and that the results were consistently reproducible.
It is common knowledge that the finer anatomic features of eyes of these experimental animals differ radically from those of human eyes. Reference was made in the original communication
