Gold-decorated, vertically grown ZnO nanorods (NRs) on a flexible graphite sheet (Au/ZnONRs/G) were developed for surface-enhanced Raman scattering (SERS)-based biosensing to identify trace amounts of human aqueous humors. This Au/ZnONRs/G SERS-functionalized sensor was fabricated via two steps: hydrothermal synthesis-induced growth of ZnO NRs on graphite sheets for nanostructure fabrication, followed by e-beam evaporator-induced gold metallization on ZnONRs/G for SERS functionalization. The thi

PURPOSE: To evaluate the efficacy and safety of orally administered grape seed proanthocyanidin extract (GSPE) in patients with non-proliferative diabetic retinopathy (NPDR). METHODS: In this randomized (1:2:2), multicentre, double-blind trial, patients (n = 124; age: 40-78 years) were administered placebo, calcium dobesilate (CD; 750 mg/d), or GSPE (150 mg/d) orally for up to 12 months. All patients had retinal thickening with hard exudates (HEs) that met predefined criteria; the median best-co

Several fabrication methods have been developed for label-free detection in various fields. However, fabricating high-density and highly ordered nanoscale architectures by using soluble processes remains a challenge. Herein, we report a biosensing platform that integrates deep learning with surface-enhanced Raman scattering (SERS), featuring large-area, close-packed three-dimensional (3D) architectures of molybdenum disulfide (MoS 2 )-assisted gold nanoparticles (AuNPs) for the on-site screening

BACKGROUND: To identify disease-specific cytokine and growth factor profile differences in the aqueous humor between wet age-related macular degeneration (AMD) patients and age-matched controls and to correlate their levels with the optical coherence tomography (OCT) findings. METHODS: Aqueous humors were obtained from 13 wet AMD eyes and 10 control eyes. Twenty cytokines and growth factors were measured using a RayBio antibody microarray technology in wet AMD and control eyes. RESULTS: The samp

The ASUWG scoring system is a reliable method of scoring UWFA images with regard to judging the activity of retinal vasculitis in ocular Behçet disease.

PURPOSE: To analyze the incidence of and risk factors for newly developed or increased macular hemorrhage after intravitreal ranibizumab injection (IVR) for neovascular age-related macular degeneration (AMD). METHODS: We performed a retrospective chart review of 220 subjects (220 eyes) from 5 hospitals who received IVRs for neovascular AMD between 1 June 2009 and 30 June 2010. Systemic conditions (age, sex, presence of diabetes, hypertension, cardiovascular disease, smoking, and use of anticoagu

Blinding retinal diseases become more epidemic as the population ages. These diseases, such as diabetic retinopathy and macular edema, are of chronic nature and require protracted drug presence at the disease site. A sustained intravitreal porous silicon delivery system with dexamethasone (pSiO2-COO-DEX) was evaluated in a new rabbit model of proliferative vitreoretinopathy (PVR) in a real treatment design. In contrast to the pretreatment design model, pSiO2-COO-DEX was intravitreally injected i

BACKGROUND: Increasing interest in microincision cataract surgery has led to the use of more flexible intraocular lens (IOL). Flexible IOL may cause more IOL deformation and refractive error when capsule contraction syndrome (CCS) occurred. In this retrospective observational case series study, the aim was to report four cases of hyperopic shift caused by CCS after phacoemulsification with microincision foldable intraocular lens implantation. CASE PRESENTATION: All of four patients underwent pha

BACKGROUND: To determine whether it would be effective in predicting the results of the postoperative full-thickness macular hole (FTMH) closure when intraretinal cyst (IRC) is present. METHODS: Case-control study. Patients with idiopathic FTMH who underwent pars plana vitrectomy with internal limiting membrane peeling were retrospectively reviewed. Preoperative spectral-domain optical coherence tomography was undertaken in all patients. The new parameter, macular hole closing factor (MHCF) was

Abstract In this study, we investigate the biochemical characteristics of oxidative stress in age‐related macular degeneration (AMD) and diabetic retinopathy (DR) by analyzing aqueous humors. Nondiabetic cataract aqueous humor was used as the control. The level of oxidative damage was evaluated based on changes in Raman spectral intensity. Seven prominent peaks were detected at 1002, 1043, 1062, 1352, 1419, 1454, and 1656 cm −1 . We proposed four multimodal biomarkers to distinguish these peaks

PURPOSE: This study used five clinical assessments and Raman spectroscopy to investigate the age- and hyperglycemia-related properties of the murine retina over an eight-week experimental period. METHOD: Acute hyperglycemia and chronic hyperglycemia were assessed with blood glucose (BG) and glycated hemoglobin (HbA1c) levels, respectively. Changes in the retinal thickness and neovascularization were evaluated with optical coherence tomography and fluorescein angiography (FAG). Histological chang
