Abstract
The aim of this study was to investigate the role of systolic blood pressure (SBP)
and diastolic blood pressure (DBP) in the development of diabetic retinopathy (DR) in type 1 and
type 2 diabetes and to determine the differences between these two types of diabetes. This cross-sectional
study included 84 patients with type 1 diabetes (T1DM) and 107 patients with type 2 diabetes
(T2DM). Ophthalmologic retinal examination included indirect slit-lamp fundoscopy, color fundus
photography according to EURODIAB (EUROpe and DIABetes) protocol and optical coherence
tomography. Blood pressure was measured with a mercury sphygmomanometer after a 10-minute rest
period. In T1DM, DR was positively associated with SBP (p = 0.035), HbA1cmedian (p < 0.001) and
hypertensive retinopathy (p < 0.001), while in T2DM DR was positively related only to HbA1cmedian
(p = 0.021). Binary logistic regression analysis (no DR/DR) showed that diabetes duration and
HbA1cmedian were the main predictors of DR in both types of diabetes. In contrast, SBP (OR = 1.05,
p = 0.045) and hypertensive retinopathy (OR = 3.75, p < 0.001) were the main predictors/indicators
of DR only in T1DM. In conclusion, blood pressure is associated with DR in type 1 but not in type 2
diabetes.
