Retinal capillary density in relation to diabetes duration and levels of glycaemia in young patients with type 1 diabetes

Acta Ophthalmologica, EarlyView.
Abstract Purpose To examine retinal capillary plexus characteristics and their correlation with diabetes duration and levels of glycaemia in young type 1 diabetes (T1D) patients. Methods Cross‐sectional analysis of baseline data from an observational, prospective cohort study of 69 patients with T1D aged 6–32 (mean 16) years in T1D duration subgroups ≤

Correcting Axial Length‐Related Magnification Errors in Optical Coherence Tomography Angiography Improves Machine Learning Classification Performance in High Myopia

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background To determine whether axial length‐related magnification correction in optical coherence tomography angiography (OCTA) improves machine learning classification of high myopia and resolves inconsistencies in the values and discriminatory power of OCTA microvascular metrics.

Rethinking diabetic retinopathy: Homeostatic mechanisms for retinal clearance

Diabetic Medicine, EarlyView.
In the healthy retina, balanced production and clearance of metabolic waste and fluid maintain retinal homeostasis and normal visual function. Diabetes disrupts this balance, increasing the accumulation of metabolic waste products, including advanced glycation end products (AGEs) and advanced lipoxidation end products (ALEs), while impairing waste and ...

Distinct ocular microvascular alterations in Alzheimer's disease and cerebral small vessel disease

Alzheimer's &Dementia, Volume 22, Issue 9, September 2026.
Abstract INTRODUCTION While both Alzheimer's disease (AD) and cerebral small vessel disease (CSVD) involve vascular dysfunction, the ocular microvascular differences between them remain largely underinvestigated. METHODS This cross‐sectional study included 650 participants (149 AD, 276 CSVD, and 225 cognitively unimpaired individuals).

Abnormal Glycaemic Fluctuations Associated With Early Microvascular Changes in the Retina and Choroid of Nondiabetic Adults

Diabetes, Obesity and Metabolism, Volume 28, Issue 9, Page 7864-7874, September 2026.
ABSTRACT Aims To evaluate the association between continuous glucose monitoring (CGM)‐derived glycaemic variability indicators and early microvascular changes of the retina and choroid in nondiabetic individuals. Materials and Methods Community‐based individuals at high risk for type 2 diabetes (T2DM) underwent detailed assessments including oral ...

Case series: The role of retinal ischemia in the pathogenesis and clinical manifestation of diabetic retinopathy

Optometry and Vision Science, Volume 103, Issue 8, August 2026.
ABSTRACT Purpose To highlight retinal ischemia as an important component of diabetic retinopathy (DR) pathogenesis, a significant prognostic factor, and a driver of various DR complications, including neovascularization. We aim to describe the main features of ischemic areas that can be identified through fundoscopy, color fundus photography, optical ...
