About one-third of individuals with diabetes develop diabetic retinopathy (DR), with one-tenth experiencing vision-threatening conditions such as diabetic macular edema (DME) or proliferative diabetic retinopathy (PDR). Current treatments only show recovery in 50% of cases, and the disease often remains asymptomatic. Therefore, novel early detection methods and new biomarkers are crucial.

Sci Rep

December 2024

Department of Computer Science and Information Engineering, Asia University, Taichung, 413, Taiwan.

Diabetic Retinopathy (DR) stands as a significant global cause of vision impairment, underscoring the critical importance of early detection in mitigating its impact. Addressing this challenge head-on, this study introduces an innovative deep learning framework tailored for DR diagnosis. The proposed framework utilizes the EfficientNetB0 architecture to classify diabetic retinopathy severity levels from retinal images.

DR is a complex complication of DM with multiple biochemical pathways implicated in its genesis and progression. Circulating OS and mitochondrial function biomarkers represent potential candidates in the DR staging system. We conducted a comparative cross-sectional study comparing the OS biomarkers: TAC, GR, NOS, CARB, and hydroperoxydes, as well as mitochondrial function biomarkers: ATP synthase and ATPase activity in healthy volunteers, DM w/o DR, Moderate and Severe NPDR, and PDR.

Diabetic macular oedema (DME) is a major cause of vision impairment in individuals with diabetes mellitus, characterised by fluid accumulation in the macula due to increased vascular permeability. The growing prevalence of diabetes worldwide has led to an increasing burden of DME on healthcare systems. While current treatment options such as anti-vascular endothelial growth factor (anti-VEGF) injections, corticosteroids, and laser therapy exist, the variability in patient responses highlights the need for reliable prognostic tools.

Background: Diabetic retinopathy is a major cause of sight loss in people with diabetes. The most severe form, proliferative diabetic retinopathy, carries a high risk of vision loss, vitreous haemorrhage, macular oedema and other harms. Panretinal photocoagulation is the primary treatment for proliferative diabetic retinopathy.

Prevalence of Diabetic Retinopathy Among Native Americans with Diabetes at a Tribal Clinic in Oklahoma.

J Racial Ethn Health Disparities

December 2024

Dean McGee Eye Institute, University of Oklahoma, 608 Stanton L Young Blvd, Oklahoma City, OK, 73104, USA.

Purpose: Native Americans (NAs) have the highest prevalence of diabetes mellitus (DM) of any racial group in the USA and are therefore at higher risk for diabetic retinopathy (DR) and diabetic macular edema (DME). This study estimated the prevalence of DR and DME among NAs receiving eye exams at the Citizen Potawatomi Nation (CPN) clinic, a tribal clinic in Oklahoma serving members of multiple tribes, and characterized risk markers associated with the presence and severity of DR.

Methods: A retrospective chart review identified tribal members with DM who received dilated retinal fundus exams at the CPN clinic between 2021 and 2023.

Invest Ophthalmol Vis Sci

December 2024

Guangdong Eye Institute, Department of Ophthalmology, Guangdong Provincial People's Hospital (Guangdong Academy of Medical Sciences), Southern Medical University, Guangzhou, China.

Purpose: The purpose of this study was to explore the succession of the central and peripheral neurovascular and microstructural impairments in patients with full-course diabetic retinopathy (DR), consisting of preclinical DR, nonproliferative DR (NPDR), and proliferative DR (PDR).

Methods: Our analysis included 81 participants (including 23 healthy controls, 23 with preclinical DR [diabetes without retinopathy], 13 with NPDR, and 22 with PDR) from the Guangdong Diabetic Retinopathy Multiple Omics Study. Retinal structure and function were evaluated and quantified using ultra-widefield swept-source optical coherence tomography angiography (UWF-SS-OCTA), electroretinography (ERG), and adaptive optics scanning laser ophthalmoscopy (AOSLO).

Purpose: To compare two artificial intelligence (AI)-based Automated Diabetic Retinopathy Image Assessment (ARIA) softwares in terms of concordance with specialist human graders and referable diabetic retinopathy (DR) diagnostic capacity.

Methods: Retrospective comparative study including 750 consecutive diabetes mellitus patients imaged for non-mydriatic fundus photographs. For each patient four images (45 degrees field of view) were captured, centered on the optic disc and macula.

In this case series of two patients, we discuss pachychoroid as a risk factor for predicting exudative retinal detachment (RD) after panretinal photocoagulation (PRP). The first patient was a 55-year-old diabetic male with unstable proliferative diabetic retinopathy (PDR), serous pigment epithelial detachment (PED), and pachychoroid confirmed via fluorescein angiography (FA) and optical coherence tomography (OCT), who underwent PRP. Post-PRP, the patient complained of visual loss in both eyes.

Article Synopsis
  • Empagliflozin may reduce the risk of diabetic retinopathy (DR) by preventing the loss of retinal pericytes, but its effectiveness compared to DPP4 inhibitors in patients with type 2 diabetes (T2D) is not well established.
  • A study was conducted using U.S. insurance claims data from 2014 to 2019, focusing on adults with T2D who were newly prescribed either empagliflozin or a DPP4 inhibitor, and looking at the incidence of nonproliferative DR and its progression.
  • Results showed that among matched patient pairs, empagliflozin's impact on the rates of incident DR and progression was analyzed, with significant data collected over an average

Purpose: To evaluate the effect on outer retina integrity of foveal sparing internal limiting membrane (ILM) peeling compared to standard ILM peeling on proliferative diabetic retinopathy (PDR) eyes affected by diabetic macular edema (DME) and epiretinal membrane (ERM).

Materials And Methods: Eyes diagnosed with PDR, DME and ERM eligible for vitrectomy were prospectively recruited and randomly assigned to either foveal sparing (FS) group and no foveal sparing (nFS) group. Ellipsoid zone (EZ) lesion size, EZ reflectivity and external limiting membrane (ELM) integrity and angular sign of Henle Fiber Layer Hyperreflectivity (ASHH) were assessed preoperatively and 1 year postoperatively.

Purpose: This study aims to explore glucose-6-phosphate dehydrogenase (G6PD) activity in diabetic retinopathy (DR) and its correlation with inflammatory factors, elucidating the regulatory role of G6PD in DR pathology.

Methods: A total of 151 T2DM patients were divided into three groups: diabetes without retinopathy (DNR, n = 59), non-proliferative retinopathy (NPDR, n = 46) and proliferative retinopathy (PDR, n = 49). Plasma G6PD activity was measured by a Randox G6PD kit and compared between these groups.

Importance: Some eyes with proliferative diabetic retinopathy (PDR) treated to stability with panretinal photocoagulation (PRP) continue to lose vision without diabetic macular edema. One presumed cause is macular capillary nonperfusion (CNP)-associated ischemia or infarction. Natural history data of macular CNP might guide treatment trials for it.
