Purpose. To evaluate the capacity of OCT angiography (OCTA) for detecting infraclinical lesions in parafoveal capillaries in diabetic patients without diabetic retinopathy (DR). Methods. This prospective observational cross-sectional case-control study analyzed the superficial and deep capillary plexuses (SCP and DCP) on macular OCTA scans (3 × 3 mm) centered on the fovea. We compared 22 diabetic patients (34 eyes included) without DR diagnosis on color fundus photographs, with 22 age- and gender-matched nondiabetic controls (40 eyes included). Qualitative analysis concerned morphological ischemic capillary alterations. Quantitative analysis measured foveal avascular zone (FAZ) size, parafoveal capillary density, and enlargement coefficient of FAZ between SCP and DCP. Results. Neither the qualitative nor quantitative parameters were significantly different between both groups. No microaneurysms or venous tortuosity was observed in any of the analyzed images. On the SCP, the mean FAZ area was 0.322 ± 0.125 mm2 in diabetic patients and 0.285 ± 0.150 mm2 in controls, P=0.31. On the DCP, the mean FAZ area was 0.444 ± 0.153 mm2 in cases and 0.398 ± 0.138 mm2 in controls, P=0.20. Conclusion. OCTA did not detect infraclinical qualitative or quantitative differences in parafoveal capillaries of diabetic patients without DR in comparison with nondiabetic controls.

Background: Diabetic retinopathy is a common microvascular complication of diabetes. Previous research has shown that the macrovascular complications of diabetes, including stroke, are often comorbid with shared and, possibly, synergistic pathology. Methods: This is a secondary analysis of the subgroup of patients who enrolled in the ACCORD Eye study of ACCORD. The primary outcome is stroke during follow-up. The primary predictor was presence of diabetic retinopathy on the Early Treatment Diabetic Retinopathy Study Severity Scale as assessed from seven-field stereoscopic fundus photographs at study baseline. We fit adjusted Cox models to the primary outcome to provide hazard ratios for stroke and included interaction terms with the ACCORD randomization arms. Results: We included 2,828 patients with a mean (SD) age of 62.1 years and 61.8% were male. The primary outcome of stroke was met by 117 patients during a mean (SD) of 5.4 (1.8) years of follow-up. Diabetic retinopathy was present in 874/2,828 (30.9%) of patients at baseline, and was more common in patients with stroke versus without stroke (41.0 vs 30.5%, p=0.016). In the Cox model, adjusted for baseline patient age, gender, race, total cholesterol, Hgb A1c, smoking, and randomization arm, we found that diabetic retinopathy remained associated with incident stroke (HR 1.60, 95% CI 1.10-2.32, p=0.015) (Figure 1). This association was not affected by randomization to the ACCORD glucose intervention (p=0.305), lipid intervention (p=0.546), or blood pressure intervention (p=0.422). Conclusion: Diabetic retinopathy is associated with an increased risk of stroke, which suggests that the microvascular pathology inherent to diabetic retinopathy has larger cardiovascular implications.
