The
Vitreous Body in 3-D

M.D.
Euro
Times review
In 1970 a new anatomical structure came to light:
The Bursa Premacularis. Other typical intravitreal structures
followed. The results of the dissections and injections are
illustrated in this vitreous anatomy three-dimensional publication.
The inner part of the eye has a fascinating anatomy. When dissecting
eyes and injecting ink in various parts of the vitreous body,
structures appear, with which only a few people became familiar. The
author combined his profession as an eye surgeon with his
photography hobby. A systems approach of the results appear in this
book. Stereopictures make it possible to view a globe and its
vitreous content, in three -dimensions.
Introduction
The anatomical study of the structure of the vitreous body is
greatly limited by two factors: its transparency and its extremely
high water content, wherefore fixation leads to extreme deformation
and structural loss.
Efforts
in the past to elucidate fine details of semi-macroscopical nature
therefore have escaped notice, except in the hands of ancient
researchers as for instance Petit, Zinn, Martegiani, Berger and
Stilling.
With
the advent of histological techniques hardly any further information
has become available. A serendipitous examination of vitreous body
in 1970 using an ancient subaqueous technique and injection of dyes
revealed a new structure called the Bursa Premacularis.
This
basic anatomical discovery has been left dormant. In particular
because functional correlations with this highly structured
premacular intravitreal structure were difficult to establish.
A
peeling technique has been used whereby the sclera, choroid and
retina are progressively removed and great effort is made to avoid
any damage to the surface and of the membranes in the vitreous.
Simplifications
of the dissection technique: (sub-aqueous dissection and
simultaneous ink injection) have revealed a number of additional
anatomical details, published in the book "Cisternal Anatomy of
the Vitreous" by Worst, Jan G.F. and Los, Leonie I.
The
transparent vitreal structures can best be depicted by
three-dimensional photography.
