Abstract:
Epiretinal and vitreal membrane formation may be considered as a uniform reaction to various etiological factors. As a comprehensive term for the various stages of this intraocular tissue proliferation the term "proliferative vitreoretinal reaction" is proposed. Derived from a clinical and ultrastructural analysis of such membrane formations 3 stages may be differentiated. From findings it is induced that the clinically so important tractional phenomena have their morphologic correlate primarily in cellular contraction.
