[The origin of papillary neovascularization in patients with proliferative diabetic retinopathy].
Vestn Oftalmol. 2004 Jul-Aug; 120(4):7-11.VO

Abstract

The case study covers examinations of 63 patients with diabetes mellitus (DM), type 1, and with proliferative diabetic retinopathy (PDR). According to the results of fluorescence angiography, the patients were shared between 3 groups: Group 1--early contrasting of papillary vascular neoplasms; Group 2--late contrasting; and Group 3--mixed contrasting. We explained the available differences by that the vascular neoplasms of the optic nerve disk (OND) originate from 2 main blood supply basins, i.e. choroidal and retinal ones. They reflect, with respect to the above stated, the hemodynamic properties of the choroidal mycocirculation, which is characterized by a higher hemodynamic load and a higher intravascular pressure, or the retinal hemomicrocirculation. The pathological signs of diabetic retinopathy in the choroidal system may fail to correlate with changes in the retinal vascular system itself. Therefore, the findings of fluorescence angiography do not always represent the genuine scope of pathological manifestations occurring in the hemomicrocirculation system in case of PDR.
