OBJECTIVE: The aim of the study was to investigate the prevalence and the risk factors of maculopathy detected by optical coherence tomography (OCT) in a Chinese population with diabetes or prediabetes. Methods. 8,155 people were randomly selected to participate in the 2011 annual Health Examination Survey in Beijing. A 75 g oral glucose tolerance test (OGTT) was tested in 3760 subjects with fasting plasma glucose (FPG) ≥ 5.6 mmol/L. Of 3,760 subjects, 583 were also randomly selected to take OCT...

PURPOSE: To determine the association of age-related maculopathy susceptibility2 (ARMS2) gene polymorphisms with the 3-year outcomes of photodynamic therapy (PDT) in wet age-related macular degeneration (wet AMD). METHODS: The single nucleotide polymorphism (SNP) at rs10490924 in the ARMS2 gene of 65 patients with wet AMD who underwent PDT was genotyped using the TaqMan assay. The clinical characteristics and the outcomes of PDT were compared among the three genotypes at rs10490924...

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...

Importance: C-reactive protein (CRP) is a circulating inflammatory marker associated with late age-related macular degeneration (AMD). It remains uncertain whether the association between CRP concentrations and AMD is causal. Objective: To assess whether CRP (OMIM 123260) single-nucleotide polymorphisms that influence circulating CRP concentrations are associated with late AMD. Design, Setting, and Participants: Participants in 2 UK, hospital-based, case-control studies (Cambridge AMD study and Moorfields Eye Hospital AMD study) and 1 pan-European, cross-sectional, population-based study (the European Eye [EUREYE] Study) were recruited between November 6, 2000, and April 30, 2007...

OBJECTIVES: Vitamin D status has been hypothesized to protect against development of early age-related macular degeneration (AMD) via its anti-inflammatory properties and its possible beneficial influence on blood pressure control. We investigated the association between vitamin D status and prevalent early AMD in a community-based cohort. DESIGN: This was a cross-sectional study. SETTING: This was a secondary data analysis of already existing data from the Atherosclerosis Risk in Communities Study (ARIC) cohort collected from 1990 to 1995...

We performed a genome-wide association study on 377 cases of neovascular age-related macular degeneration (AMD) and 1074 controls to determine the association of previously reported genetic variants associated with neovascular AMD in the Thai population. All patients were of Thai ancestry. We confirmed the association of age-related maculopathy susceptibility 2 (ARMS2) rs10490924 (P=7.38 × 10(-17)), HTRA1 rs11200638 (P=5.47 × 10(-17)) and complement factor H gene (CFH) rs800292 (P=2.53 × 10(-8)) with neovascular AMD, all loci passing the genome-wide significance level (P<5...

PURPOSE: To evaluate the efficacy of intravitreal ocriplasmin for the resolution of vitreomacular traction (VMT) with or without a full thickness macular hole (FTMH) in the clinical setting and to assess whether the indication spectrum of this treatment modality can be expanded beyond that of the MIVI-TRUST trials. METHODS: The records of patients with VMT with or without FTMH, who were treated with intravitreal ocriplasmin were reviewed. Patients were divided in two groups...

Age-related macular degeneration (AMD) is a major cause of blindness in older adults in developed countries. It is a multifactorial disease triggered by both environmental and genetic factors. High-temperature requirement A serine peptidase 1 (HTRA1) and age-related maculopathy susceptibility 2 (ARMS2) are two genes that are strongly associated with AMD. Because ARMS2 is an evolutionarily recent primate-specific gene and because the ARMS2/HTRA1 genes are positioned at a locus on chromosome 10q26 in a region with strong linkage disequilibrium, it is difficult to distinguish the functions of the individual genes...

PURPOSE: Age-related macular degeneration (AMD) is one of the leading causes of blindness in the elderly population. Although there are prevalence studies for AMD in Europe, data are scarce for the Slovakian population. METHODS: This was a prospective, multicenter, non-interventional, mobile clinic-based cross-sectional study that assessed age-specific prevalence of AMD in the Slovakian population and risk factors associated with AMD. The type of AMD was graded based on the international age-related maculopathy grading system; optical coherence tomography (OCT) was used for the differential diagnosis...

Purpose: Oxidative stress, characterized by an excessive production of reactive oxygen intermediates has been suggested to play a role in the pathogenesis of age-related macular degeneration (AMD). We examined the association of urinary F2-isoprostanes (F2-IsoPs), a marker of lipid peroxidation and the most reliable marker of oxidative damage with AMD. Methods: We included 238 adults with AMD and 390 age- and sex-matched controls without AMD who participated in a population-based cross-sectional study in Singapore (Singapore Chinese Eye Study, 2009-2011)...

BACKGROUND: Torpedo maculopathy is a rare, congenital maculopathy classically diagnosed funduscopically as a 'torpedo-shaped' lesion located temporal to the fovea. This case describes a torpedo maculopathy with non-classic optical coherence tomographic (OCT) findings and collaborative OCT angiographic (OCTA) findings. CASE REPORT: A 60-year-old Caucasian woman presented with a history of longstanding distortion and paracentral scotoma of the right eye. She had a positive family history of age-related macular degeneration...

Maculopathy is the excessive damage to macula that leads to blindness. It mostly occurs due to retinal edema (RE), central serous chorioretinopathy (CSCR), or age related macular degeneration (ARMD). Optical coherence tomography (OCT) imaging is the latest eye testing technique that can detect these syndromes in early stages. Many researchers have used OCT images to detect retinal abnormalities. However, to the best of our knowledge, no research that presents a fully automated system to detect all of these macular syndromes is reported...

PURPOSE: To conduct an assessment of avoidable blindness and diabetic retinopathy (DR) in Gilan, 2014. METHODS: A cross-sectional population-based survey was performed on a representative sample of urban and rural individuals aged ≥50 years of the province. Blindness was defined as presenting visual acuity (PVA) <3/60 in the better eye. Moderate visual impairment (MVI) and severe visual impairment (SVI) were defined as 6/60 ≤ PVA <6/18 and 3/60 ≤ PVA <6/60 in the better eye, respectively...

Importance: The ocular manifestations and sequelae of Zika virus infection are not well known. Recently, the World Health Organization changed the declaration of Zika as a public health emergency and designated the viral outbreak and related microcephaly clusters as a long-term program of work. This change indicates the urgent need to evaluate and document ophthalmic manifestations in patients for timely management of this disease. In addition, confirmation whether the public health problem in Brazil extends to other regions in South America is needed...

Importance: Understanding the link between ethnicity and health is critical to making appropriate public policy decisions. Few population-level data are available about this connection, however, including the influence of ethnicity on the association between age-related macular degeneration (AMD) and vision-specific functioning (VSF). Objective: To identify the influence of ethnicity on VSF among Chinese, Malay, and Indian patients with AMD.
