background: we aimed here to investigate the association between alleles and genotypes of apoe and age-related macular degeneration (amd) development. materials and methods: after ophthalmological examination, 120 patients with confirmed amd and 120 healthy controls were enrolled in the study. the polymorphic segment of apoe gene was pcr-amplified and sequenced to determine the frequency distri...

age-related macular degeneration (amd) is the most common cause of irreversible vision loss and debilitating disease in old age, which involves the central retina/macula among elderly patients. the genetic and environmental factors have important role in this multifactorial disease. oxidative stress and dna damages would have important impact on the onset and progression of amd.  in this study,...

PURPOSE Dietary carotenoids lutein and zeaxanthin may play a protective role against visual loss from age-related macular degeneration (AMD) through antioxidant and light screening mechanisms. We used a novel noninvasive objective method to quantify lutein and zeaxanthin in the human macula using resonance Raman spectroscopy and compared macular pigment levels in AMD and normal subjects. DESI...

As the medical community has accepted that age-related macular degeneration (AMD) is a disease influenced by genetics, so too has it uncovered patterns in patients’ genetic profiles that suggest some individuals are at increased risk for initiation or progression of the disease. However, genetics is not everything, and retina specialists need to remember that AMD is a complex disorder that is a...

The authors conducted a study to determine a way of overcoming the poor-quality demonstration of choroidal neovascularization (CNV) associated with age-related macular degeneration (AMD) on conventional magnetic resonance (MR) imaging studies. The poor MR imaging demonstration of CNV in patients with AMD makes the use of gamma knife surgery more difficult. This difficulty, however, can be overc...

BACKGROUND The neovascular form of age-related macular degeneration (AMD) can rapidly lead to severe loss of central vision and adversely affect the patient's quality of life. During the 1990s the only proven treatment for neovascular AMD was laser photocoagulation. Only a minority of patients are eligible to receive this treatment, however, and the treatment itself can cause acute retinal dama...

BACKGROUND We investigated the serological association of Chlamydia pneumoniae infection with age-related macular degeneration (AMD). METHODS A systematic review and meta-analysis was performed. PubMed, Embase, Web of Science and the Association of Research in Vision and Ophthalmology abstracts were searched to identify studies investigating the serological association of Chlamydia pneumoniae...

AIM To assess the efficacy of pegaptanib as maintenance therapy in neovascular age-related macular degeneration (NV-AMD) patients after induction therapy. METHODS A phase IV, prospective, open-label, uncontrolled exploratory study including subjects with subfoveal NV-AMD who had had one to three induction treatments 30-120 days before entry and showed investigator-determined clinical/anatomic...

BACKGROUND Fibrotic disciform scars represent the end-stage of wet age-related macular degeneration (AMD) and ophthalmologists tend not to treat them. However, reactivation can occur resulting in further worsening of patients. The aim of this study is to describe the clinical outcomes of 10 patients with disciform scars from age-related macular degeneration (AMD) that have subsequently reactiva...

RATIONALE  Choroidal neovascular (CNV) lesions in younger patients are often accompanied by the appearance of a surrounding ring of pigment that is associated with disease regression or slowed disease progression. In older patients with age-related macular degeneration (AMD), however, hypertrophy of the retinal pigment epithelium (RPE) is known to occur but has not previously been reported to b...
