[Retinal detachment, caused by hyperaemia of the choroid? Remarks on the supposed relationship between retinal detachment and "indirect trauma" (author's transl)]

Abstract

It was recently stressed by Scheerer that retinal detachment in a highly myopic eye may be caused by hyperaemia of the choroid, presumably occuring during heavy physical labour which is performed by a non-trained person. Clinical studies have shown, however, that choroidal detachment, resulting from either hemorrhagic, or serous accumulation of fluid during operative procedures or during postoperative periods, is not followed by retinal detachment. Also experimental occlusion of large choroidal vessels, associated with hyperaemia in the choroidal vasculature, does not lead to retinal changes inducing the separation of the neuroretina from the pigment epithelium layer. Thus, it is concluded that choroidal hyperaemia, possibly occuring during heavy physical labour, has no relationship to the development of a retinal detachment in a "disposed" eye.
