Decreased retinal capillary density is associated with a higher risk of diabetic retinopathy in patients with diabetes

Purpose: To quantify retinal microvascular alterations using optical coherence tomography angiography in diabetic patients, and to evaluate the accuracy of decreased vessel density (VD) in predicting early diabetic retinopathy (DR). Methods: One hundred and two eyes of 51 diabetic patients and 92 eyes of 46 individuals without diabetes were examined. Duration of diabetes, insulin therapy, blood pressure, HbA1C, dyslipidemia, axial length, and the presence of DR were recorded. Retinal VD was measured using optical coherence tomography angiography. The effect of risk factors on VD and on DR was assessed using multivariable regression analyzes. Results: Compared with controls, VD was lower in diabetic patients (P

Authors: Liebenthal R, Butler S, Coppola J, Shah B Abstract BACKGROUND: Use of a universal diagnostic catheter may decrease procedural time and catheter-exchange related spasm when compared with a dual-catheter strategy. The aim of this study was to identify preprocedural predictors of failure to complete a coronary angiogram with a universal catheter alone. METHODS: Consecutive patients (n = 782) who underwent a right transradial/transulnar coronary angiogram with a single operator were retrospectively reviewed. Multivariable predictors of failure to complete the procedure with a universal catheter alone were ...

CONCLUSIONS: Our results indicate that the TCF7L2 rs12255372 and rs7903146 polymorphisms do not influence T2DM in Brazilian patients with the high risk for CAD. Therefore, we assume that these variants may only be relevant for a specific subgroup of T2DM patients or some particular human population. PMID: 31517619 [PubMed - in process]

Abstract PURPOSE: To characterise the non-perfused areas (NPAs) in the superficial and deep capillary layers (sNPAs and dNPAs, respectively) in the posterior pole in proliferative diabetic retinopathy (PDR) on wide-field optical coherence tomography angiography (OCTA) images. METHODS: We retrospectively reviewed 104 eyes of 70 patients with PDR from whom wide-field swept source OCTA images were acquired. sNPAs and dNPAs were manually measured in each quadrant of the inner (1-3 mm diameter), intermediate (3-6 mm), and outer (6-10 mm) rings centred on the fovea. Two qualitative findings, th...

CONCLUSION: Clinical course and long-term prognosis of ISS might be benign. Most cases of ISS could be improved or not aggravated. Control of medical co-morbidity might be important. To the best of our knowledge, our study had more cases with longer follow-up period of time than other reports. PMID: 31484229 [PubMed]

Walking is often touted as a perfect exercise to improve multiple aspects of health. But what if walking causes leg pain? Many people shrug off leg pain when they walk as a normal part of aging. In some cases, though, it’s the sign of peripheral artery disease (PAD), which can put heart and brain health at risk. While PAD doesn’t usually run in families, it’s more likely to occur as people age, or among people who smoke or have high blood pressure, high cholesterol, or diabetes. What causes leg pain if you have PAD? People with PAD have fatty deposits in arteries outside the heart — most often in th...

ConclusionsThis review aims to establish the current application of OCTA to anterior segment disorders of the eye, with an emphasis on exploring its use in iris vessel dilation seen in various forms of iritis, as a predictive factor for further episodes of inflammation. In addition, OCTA can depict neovascularization of the iris secondary to proliferative diabetic retinopathy.

AbstractPurpose of ReviewDiabetic retinopathy (DR) is the leading cause of acquired vision loss in adults across the globe. Early identification and treatment of patients with DR is paramount for vision preservation. The aim of this review paper is to outline current and new imaging techniques and biomarkers that are valuable for clinical diagnosis and management of DR.Recent FindingsUltrawide field imaging and automated deep learning algorithms are recent advancements on traditional fundus photography and fluorescein angiography. Optical coherence tomography (OCT) and OCT angiography are techniques that image retinal anat...
