[Microcirculatory disorder in the bulbar conjunctiva of patients with diabetic retinopathy].

Biomicroscopy was employed to study the state of microcirculation of the bulbar conjunctiva in 166 patients with diabetes mellitus at different stages of the ophthalmoscopic assessment of the fundus of the eye. Disorder in conjunctival microhemodynamics was found in 89.7% of the patients, in the presence of retinopathy in all the cases and in a normal picture of the fundus of the eye in 69.3%. Qualitative and quantitative changes in microcirculation of the conjunctiva were shown to depend on the stage and form of diabetic retinopathies. Values of changes of the total conjunctival index and its constituents were on an increase with aggravation of a pathological process in the fundus of the eye. Vascular changes prevailed in the diabetic-sclerotic and diabetic-hypertensive forms of retinopathies, intravascular changes and perivascular edema prevailed in the diabetic-renal form.
