BACKGROUND: Diabetic retinopathy (DR) is a sight-threatening retinal disease with pathological mediation by vascular endothelial growth factor (VEGF). Intravitreal anti-VEGF injections are commonly used to manage DR. Ultra-wide-field fluorescein angiography (UWF-FA) can assess DR severity and characterize the amount of non-perfused retina (non-perfusion area, NP), neovascularization (neovascular area, NV), and foveal avascular zone (FAZ). However, the association between anti-VEGF treatment and NP, NV, and FAZ characterized by UWF-FA is not well established.
METHODS: A retrospective, single-center cohort study involved eyes of patients with Type 1 or 2 diabetes mellitus with at least one UWF-FA image. The area of the FAZ, …

Purpose: To study the influence of ultra-widefield fluorescein angiography (FA) on the diagnosis and management of diabetic retinopathy (DR).
Methods: Ten experts in DR completed an online survey in which they were asked to diagnose and manage DR cases using different imaging modalities. Experts independently reviewed 20 cases of DR and provided a diagnosis and management plan for each case, first based on ultra-widefield color-free and red-free images alone and again with the corresponding ultra-widefield FA images. Experts were polled on their diagnostic confidence, use of FA in clinical practice, and opinions on the value of ultra-widefield FA. Based on …

Diabetic retinopathy is a severe complication of diabetes that is capable of causing vision loss or blindness. As a result of hyperglycemia, the disease increases oxidative stress and activates biochemical processes such as the Hippo pathway and the complement system to cause significant damage to the retina. Overexpression of BTG1 and microRNA-183 enables activation of biochemical pathways that lead to negative effects on the retinal vascular endothelium including angiogenesis and inflammation. Conventional methods of diagnosis for diabetic retinopathy include fundus examination, nucleoside detection, and optical coherence tomography angiography. Photocoagulation and hormonal intravitreal injection are the most popular current treatments, while …

PURPOSE: The purpose of this study was to assess the comparability of mean sensitivity (MS) values obtained using the Macular Integrity Assessment (MAIA; CenterVue S.p.A. [iCare], Padova, Italy) and Microperimeter-3 (MP-3; NIDEK CO., Ltd., Gamagori, Japan) microperimetry (MP) devices.
METHODS: This cross-sectional study includes subjects with healthy eyes, eyes with diabetes mellitus without diabetic retinopathy (DM no DR), diabetic retinopathy (DR), and non-exudative age-related macular degeneration (AMD). Patients underwent testing on both MAIA and MP-3 MP devices, using a 10-2 macular grid with 68 stimuli and identical parameters. A diagnosis-adjusted linear regression model and mixed modeling mapped MP-3 MS to …

Introduction: The development of autonomous artificial intelligence for interpreting diabetic retinopathy (DR) images has allowed for point-of-care testing in the primary care setting. This study describes patient and provider experiences and perceptions of the artificial intelligence DR screening technology called EyeArt by EyeNuk during implementation of the tool at Western Maine Primary Care in Norway, Maine.
Methods: This non-randomized, single-center, prospective observational study surveyed 102 patients and 13 primary care providers on their experience of the new screening intervention.
Results: All surveyed providers agreed that the new screening tool would improve access and annual screening rates. Some providers also identified …

Purpose/Background
More than 34 million people in the United States have diabetes. Diabetic retinopathy (DR) is a major complication of diabetes and a leading cause of vision loss. Risk factors for diabetic retinopathy include Type 1 and Type 2 Diabetes, hypertension, smoking, and being African American or Hispanic/Latino. This scoping review seeks to analyze the current research on ways to increase vision screenings, thus reducing cases of diabetic retinopathy in adults.
Methods
Between September 2020 and November 2021, a search was conducted using PubMed, EBSCOhost, Medline, and CINAHL to identify articles using keywords such as diabetic retinopathy and ophthalmology. This …

Diabetic retinopathy and age-related macular degeneration are common retinal diseases with shared pathophysiology, including oxidative stress-induced inflammation. Cellular mechanisms responsible for converting oxidative stress into retinal damage are ill-defined but have begun to clarify. One common outcome of retinal oxidative stress is mitochondrial damage and subsequent release of mitochondrial DNA into the cytosol. This leads to activation of the cGAS-STING pathway, resulting in interferon release and disease-amplifying inflammation. This review summarizes the evolving link between aberrant cGAS-STING signaling and inflammation in common retinal diseases and provides prospective for targeting this system in diabetic retinopathy and age-related macular degeneration. Further defining …

Purpose/Background Diabetic retinopathy (DR) is the leading cause of blindness in adults. Current guidelines recommend that all patients with type 2 diabetes mellitus (T2DM) have a DR screening (DRS) upon diagnosis of T2DM and then annually, but the adherence rate is only approximately 60%. This scoping review aims to evaluate the effectiveness of primary care providers (PCPs) employing strategies to increase compliance with annual DRS among adult patients with T2DM.
Methods Between September 2021 and January 2022, a literature review was performed to collect studies evaluating interventions to increase adherence to DRS. Individual searches of PubMed, SCOPUS, and CINAHL were …

The purpose of this study is to investigate and determine the role of PEDF in the pathogenesis of diabetic retinopathy as induced by advanced glycation end-products (AGEs). Human retinal pericytes were isolated from donors and will be measured for cell proliferation under the influence of PEDF both in the presence and absence of AGEs. Expected outcomes involve both the maintenance and increased survival of HRPs after treatment with PEDF under stimulated hyperglycemic conditions.

Diabetic Retinopathy (DR) is a neurovascular complication associated with diabetes mellitus that affects approximately 120 million people worldwide and its prevalence is expected to reach 190 million by 2030. DR diagnosis is accomplished with fundus ophthalmoscopy often when retinal damage and vision loss have already occurred. A group of biomarker being explored for early detection of diseases are extracellular vesicles (EVs), which are nanometer diameter lipid enclosed vesicles, released from all cell types and containing genetic cargo reflective of releasing cell state. EV biomarkers are currently being explored to help monitor disease predisposition, pathogenesis and response to treatment. While an …

Although numerous hypotheses (and potential risk factors), have been offered to explain the origins and potential mechanism(s) for central retinal vein occlusion (RVO) in patients of diverse ages, there is no agreement. Recently, considerable epidemiological evidence has been brought forth which indicates a strong association between RVO, myocardial infarctions, heart failure, and stroke. Magnesium (Mg) deficiency (mgD) has long-been associated with glaucoma and diabetic retinopathy. Over the past three decades, our laboratories have found strong associations of mgD linked to morbidity/ mortality in cardiovascular diseases such as myocardial infarctions, cardiac failure, atherogenesis, and strokes, both experimentally and clinically. More recently, …
