PURPOSE: To evaluate the properties of the microvasculature of bulbar conjunctiva and to assess the function of endothelium of the main arteries in type 1 diabetes mellitus (T1DM).
MATERIAL AND METHODS: The study included 35 patients with T1DM and initial nonproliferative diabetic retinopathy (NPDR). The control group consisted of 30 subjects. In addition to standard ophthalmic examination, all participants underwent digital bulbar capillaroscopy (DBC), pulse wave velocity (PWV) test, and plethysmography for assessment of endothelium function.
RESULTS: According to DBC, in comparison to the control group, diabetic patients with even initial NPDR had disturbances of blood microcirculation manifested as increased average venous vessel width (p=0.04), reduced arterial capillary blood flow (p=0.02), increased blood sludging (p=0.001), and increased duration of blood stasis (p=0.03). Evaluation of vessel endothelium in T1DM patients with NPDR showed increased PWV (p=0.03).
CONCLUSION: Diabetic patients with NPDR showed marked changes of capillary blood flow alongside signs of endothelial dysfunction. The most significant change was increased venous vessel width.
