KNOWLEDGE of the histologic character of the connection between Bruch's membrane and the choriocapillaris of the choroid is still very limited. A number of older authors (Iwanow,1 Arnstein,2 Sattler,3 Schwalbe,4 Smirnow,5 and Wolfrum6) investigated various histologic aspects of these membranes in men and animals but failed to explain satisfactorily the morphology of the unusually close relationship which exists between them.
Iwanow1 stated that the capillaries are so intimately connected with Bruch's membrane by means of delicate connective tissue fibers that a separation is possible only by the use of reagents which dissolve or destroy these fibers. According to Schwalbe,4 a separation of Bruch's membrane is possible in spite of a very intimate connection, but he admitted that it is very difficult. Sattler3 and Arnstein2 confirmed this opinion; none of the authors offered a morphologic explanation of this phenomenon. Smirnow5
