Atrophies 'like flows' of the retinal pigment epithelium: a neuroepithelium-draining method of the posterior pole.

17 cases of eyes affected jointly by diseases of the posterior pole (central serous chorioretinopathy, serous detachment of pigmented epithelium, melanoma, osteoma, hemangioma) and flow-like atrophy of the pigmented epithelium, originating from the lesion and always directed downwards, are presented. It is likely that serous detachment of the neuroepithelium constituting the original wound (central serous chorioretinopathy) or the secondary one (serous detachment of the pigmented epithelium) of the posterior pole prolongs itself downwards, leaving a localized atrophy as a mark on the pigmented epithelium. The eventual draining role of serous detachment of the neuroepithelium by this 'flow' is disputed.
