Microcirculation of peripheral retina and choroid features in pregnant

Abstract

With the occurrence of new research methods in ophthalmology the view on pathogenesis of rhegmatogenous retinal detachment changed. It is obvious that the cause of the formation of its defects, followed by detachment is not the degree of myopia, but the presence of certain types of peripheral vitreous chorioretinal degradations (PVCD). Methods. The research of microcirculation of peripheral retina and choroid was done in 93 pregnant women aged 18-33 with lamellar and dipnoous retinal perforations, 48 of which suffered from myopia. The microcirculation was tested with the use of computer laser analyzer LAKK-02 (Lazma, Russia). Results. In patients with PVCD there was a significant increase of wide tissue blood filling parameters, heart rate, and muscle tone of precapillar sphincter, and also the decrease of oxygen saturation of microvasculatur, especially at myopia. Conclusions. All patients with symptoms of PVCD associated with myopic refraction should be subjected to a dynamic ophthalmologic control during the whole period of pregnancy considering the microcirculation loss in peripheral retina and choroid, and high risk of new “obligate prelamellar” dystrophic changes.
