In this article, the authors draw attention of readers to the capabilities of the conjunctival microscopy (CM) the method for studying the processes of vascular permeability and microhemorheology in patients with systemic sclerosis (SS). An original simultaneous examination of 48 patients with SS (mean age 51±1,7 years) and a comparable age group (4,74±2,3 years) of the control group of people without any diseases that might affect microcirculation (MC) by the CM-method was performed. The results demonstrated high informativeness of the CM-method in the diagnostics and assessment of vascular permeability and intravascular red blood cell aggregation (RBCA) in SS. The main changes in MC during SS revealed by the CM-method are the increase in vascular permeability and enhancement of RBCA in all types of microvessels. Key words: vascular permeability, intravascular red blood cell aggregation, conjunctival microscopy, systemic sclerosis.
