PURPOSE: To determine the frequency of the genotypes of single nucleotide polymorphisms (SNPs) in the gene encoding cholesteryl ester transfer protein (CETP) and their associations with age-related macular degeneration (AMD) in the Lithuanian population. STUDY DESIGN: A total of 1264 subjects were examined: 251 patients with early AMD, 206 patients with exudative AMD, and 807 healthy controls. METHODS: The genotyping of CETP (rs5882, rs708272, rs3764261, rs1800775, rs2303790) was carried out using the RT-PCR...

Stargardt disease (STGD1) is the most common cause of inherited juvenile macular degeneration. This disease is characterized by a progressive accumulation of lipofuscin in the outer retina and subsequent loss of photoreceptors and retinal pigment epithelium. The aim of this study was to evaluate the relationship between cone photoreceptor function and structure in STGD1. Macular function was assessed by visual acuity measurement and focal electroretinogram (FERG) recording while spectral domain optical coherence tomography (SD-OCT) imaging was performed to evaluate the integrity of photoreceptors...

PurposeThe goal was to develop a simple model for predicting the individual risk profile for age-related macular degeneration (AMD) on the basis of genetic information, disease family history, and smoking habits.Patients and methodsThe study enrolled 151 AMD patients following specific clinical and environmental inclusion criteria: age >55 years, positive family history for AMD, presence of at least one first-degree relative affected by AMD, and smoking habits. All of the samples were genotyped for rs1061170 (CFH) and rs10490924 (ARMS2) with a TaqMan assay, using a 7500 Fast Real Time PCR device...

PURPOSE: To investigate the association between sex hormone deficiency and soft drusen in women and men. MATERIALS AND METHODS: We retrospectively reviewed the medical records and fundus photographs of subjects who underwent a health screening for additional examination of climacterium and age-related changes including sex hormone status. In women, sex hormone deficiency was defined as cessation of menstruation that had lasted for at least 12 months and follicular stimulating hormone (FSH) levels ≥ 25 mIU/mL; in men, it was defined as testosterone levels ≤ 3...

A 77-year-old woman with exudative macular degeneration underwent bilateral intravitreal injections of "stem cells" at a clinic in Georgia. One month and 3 months after injection, she developed retinal detachments in the left and right eyes, respectively. Increased awareness within the medical community of such poor outcomes is critical so that clinics offering untested practices that have been shown to be potentially harmful to patients can be identified and brought under U.S. Food and Drug Administration oversight...

BACKGROUND AND OBJECTIVE: To investigate the progression of retinal atrophy in patients with retinal pigment epithelium (RPE) tears secondary to neovascular age-related macular degeneration. PATIENTS AND METHODS: In this retrospective case series, patients were analyzed at two high-volume referral centers. The extension of the areas without RPE was analyzed yearly from baseline to last examination through fundus autofluorescence (FAF) imaging using Region Finder (Heidelberg Engineering, Heidelberg, Germany)...

PURPOSE: To compare the detection rate of choroidal neovascularization (CNV) in treatment-naive neovascular age-related macular degeneration by swept source optical coherence tomography angiography (SS-OCTA, Topcon's DRI Triton) working at 1,050 nm wavelength versus fluorescence angiography. METHODS: Cross-sectional analysis of 156 eyes (107 neovascular age-related macular degeneration and 49 dry AMD) in 98 patients, previously diagnosed by multimodal imaging using fluorescein (FA) and indocyanine green angiography (Heidelberg's Spectralis) in a tertiary retina center, evaluated by SS-OCTA 4...

Purpose: There is growing evidence of the importance of nutrition in age-related macular degeneration (AMD), but no prospective studies have explored the impact of vitamin D. We evaluated the association between vitamin D intake and progression to advanced AMD. Methods: Among 2146 participants (3965 eyes), 541 (777 eyes) progressed from early or intermediate AMD to advanced disease (mean follow-up: 9.4 years) based on ocular imaging. Nutrients were log transformed and calorie adjusted...

BACKGROUND AND AIMS: Age-related macular degeneration (AMD) is the worldwide leading cause of blindness among the elderly, especially in developed countries. The possible association between apolipoprotein E (ApoE) polymorphism (ε2, ε3, ε4) and AMD has been extensively investigated with conflicting results, especially when specifying different clinical phenotypes of AMD. Herein, we conducted a meta-analysis by integrating several recent large-sample studies to verify the effect of ApoE polymorphisms on AMD subtypes...

BACKGROUND: Age-related macular degeneration (AMD) is a leading cause of blindness in developed countries. Few studies have investigated its relationship to environmental neurotoxicants. In previous cross-sectional studies, we found an association between pesticide use and self-reported retinal degeneration. OBJECTIVE: We evaluated the association of pesticide use with physician-confirmed incident AMD. METHODS: The Agricultural Health Study (AHS) is a prospective cohort of pesticide applicators and their spouses enrolled from 1993-1997 in Iowa and North Carolina...

Optical coherence tomography angiography (OCTA) has emerged as a novel, non-invasive imaging modality that allows the detailed study of flow within the vascular structures of the eye. Compared to conventional dye angiography, OCTA can produce more detailed, higher resolution images of the vasculature without the added risk of dye injection. In our review, we discuss the advantages and disadvantages of this new technology in comparison to conventional dye angiography. We provide an overview of the current OCTA technology available, compare the various commercial OCTA machines technical specifications and discuss some future software improvements...

BACKGROUND & OBJECTIVES: The enzyme paraoxonase (PON), an antioxidant enzyme that has both arylesterase and thiolactonase activity, is well studied in cardiovascular diseases. Although a few studies have shown altered PON activity in ocular diseases such as age-related macular degeneration and diabetic retinopathy, but the tissue-wise expression of PON in its three gene forms has not been studied. This study was conducted to see the ocular distribution of PON for any altered expression in ocular pathologies such as in cataract and diabetes mellitus...

PURPOSE: To investigate whether vitreomacular adhesion (VMA) affects the outcome of anti-vascular endothelial growth factor (VEGF) therapy for the treatment of exudative age-related macular degeneration (AMD) in Japanese patients. SUBJECTS AND METHODS: Of 88 Japanese AMD patients (28 men and 60 women, mean age: 72.7±7.5 years) who underwent intravitreal injection of ranibizumab for 3 years from 2010 to 2013, this study involved 12 eyes of 12 patients (10 men and two women) in whom VMA was observed based on optical coherence tomography (OCT) findings (VMA [+] group) and 17 eyes of 16 patients (seven men and nine women, control group) in whom no VMA was observed (VMA [-] group)...
