Purpose: We investigate the reflectance properties of the cone mosaic in adaptive optics (AO) images of healthy subjects and subjects with nonproliferative diabetic retinopathy (NPDR) over time. Methods: We acquired images of the parafoveal cone mosaic over 5 years in 12 healthy subjects and in six patients with mild NPDR. We analyzed the parameters of the cone intensity histogram distribution (mean, SD, and skewness), two metrics of the cone mosaic texture (sharpness and entropy), and two novel metrics (cone/intercone intensity and slope of the variogram)...

The present study aimed to investigate the ability of diffusion-weighted imaging (DWI) to identify injury to the visual centers of the brain in patients with type 2 diabetes with retinopathy. The study included 84 cases (63 patients with type 2 diabetic retinopathy and 21 healthy individuals) that were assessed using DWI. Diabetic patients were equally divided into three groups: Proliferative diabetic retinopathy (PDR), non-proliferative diabetic retinopathy (NPDR) and diabetic without retinopathy. The results demonstrated that individuals in the PDR group had significantly higher disease duration and glycated hemoglobin levels than the diabetic without retinopathy group (P<0...

BACKGROUND: Conjunctival microangiopathy has been described among diabetics similar to retinal vessel angiopathy. Correlation of these conjunctival microangiopathy changes with retinopathy may form the basis of screening by external examination without expert fundus evaluation. METHODS: Conjunctival vessels widths and tortuous segment length of conjunctival vessels of 96 patients with type 2 diabetes mellitus were photographed and measured by the Zeiss Fundus camera Visupac software...

Purpose: To analyze the associations between retinal vessel geometry and the 1-year incidence and progression of diabetic retinopathy (DR) in a Chinese population. Methods: This was a prospective cohort study of adult subjects with diabetes mellitus. Retinal vascular geometry was quantified from fundus photographs using a semiautomated computer-assisted program. Diabetic retinopathy was graded from retinal photographs at baseline and 1 year. Incident DR and 2-step change in DR were analyzed...

AIMS: To assess the relationship between insulin resistance (IR), retinopathy and maculopathy in young adults with Type 1 diabetes mellitus. METHODS: A cross-sectional study at a regional Australian tertiary hospital. Retinal pathology, assessed by colour fundus photography, was correlated with two surrogate measures of IR: estimated Glucose Disposal Rate (eGDR) and Insulin Sensitivity Score (ISS), where lower scores reflect greater IR. RESULTS: 107 patients were recruited, with mean age 24...

Diabetic retinopathy (DR) is a leading cause of vision-loss globally among type 2 diabetes (T2DM) patients. Information on the economic burden of DR in Singapore is limited. We aim to identify the total annual direct medical costs of DR at different stages, and to examine factors influencing the costs. Four hundreds and seventy T2DM patients who attended the Diabetes Centre in a secondary hospital in Singapore in 2011-2014 were included. Digital color fundus photographs were assessed for DR in a masked fashion...

PURPOSE: To measure the concentrations of various cytokines in the aqueous humor from patients with different stages of diabetic retinopathy. METHODS: All selected cataract patients were categorized into 4 groups: the control group (patients without diabetes), nonretinopathy (NDR) group (diabetic patients without retinopathy), nonproliferative diabetic retinopathy (NPDR) group, and proliferative diabetic retinopathy (PDR) group. The aqueous concentrations of interleukin- (IL-) 1β, IL-2, IL-4, IL-5, IL-6, IL-10, interferon-γ, tumor necrosis factor-α, and vascular endothelial growth factor (VEGF) from patients were measured using the cytometric bead array technique...

BACKGROUND: Uric acid is a final breakdown product of purine catabolism in humans. It's a potent antioxidant and can also act as a pro-oxidant that induces oxidative stress on the vascular endothelial cells, thus mediating progression of diabetic related diseases. Various epidemiological and experimental evidence suggest that uric acid has a role in the etiology of type 2 diabetes mellitus. We conducted a cross-sectional study to evaluate the correlation of retinal nerve fibre layer (RNFL) and macular thickness with serum uric acid in type 2 diabetic patients...
