PURPOSE To evaluate the prognostic value of the cone outer segment tips (COST) and other features using spectral-domain optical coherence tomography (SD-OCT) in patients undergoing epiretinal membrane (ERM) surgery. DESIGN Retrospective observational case series. METHODS Fifty eyes of 49 patients that underwent vitrectomy for idiopathic ERM were(More)
BACKGROUND AND PURPOSE More than half of the retinitis pigmentosa (RP) cases are genetically simplex or multiplex. To date, 37 causative genes of RP have been identified; however, the elucidation of gene defects in simplex or multiplex RP patients/families remains problematic. The aim of our study was to identify the genetic causes of RP in patients with(More)
The role of microglia in neurodegeneration is controversial, although microglial activation in the retina has been shown to provide an early response against infection, injury, ischemia, and degeneration. Here we show that endogenous bone marrow (BM)-derived microglia play a protective role in vascular and neural degeneration in the retinitis pigmentosa(More)
PURPOSE To evaluate status of the external limiting membrane (ELM) as a contributor of visual acuity (VA) in age-related macular degeneration (AMD). DESIGN Hospital-based, cross-sectional study. METHODS We retrospectively reviewed spectral-domain optical coherence tomography images of 158 patients with AMD who had undergone photodynamic therapy and(More)
To evaluate the prognostic value of foveal microstructures as determined using spectral-domain optical coherence tomography (SD-OCT) in eyes with surgically closed macular holes (MHs). Thirty eyes of 30 patients that underwent successful vitrectomy for idiopathic MHs were studied. Best-corrected visual acuity (BCVA) and SD-OCT images of the fovea were(More)
Granulocyte colony-stimulating factor (G-CSF) is a known hematopoietic glycoprotein, and recent studies have revealed that G-CSF possesses other interesting properties. Oxidative stress is involved in many diseases, such as atherosclerosis, heart failure, myocardial infarction, Alzheimer disease, and diabetic retinopathy. This study was designed to examine(More)
PURPOSE To investigate the relationship between subfoveal choroidal thickness, choroidal vascular hyperpermeability, and complement factor H (CFH) gene polymorphism in typical age-related macular degeneration (AMD) and polypoidal choroidal vasculopathy (PCV). METHODS Fifty-eight patients with typical AMD and 63 patients with PCV underwent fluorescein(More)
PURPOSE To investigate whether the major genetic and environmental risk factors of age-related macular degeneration (AMD)-CFH Y402H and LOC387715 A69S and cigarette smoking-are also associated with polypoidal choroidal vasculopathy (PCV) and whether the associations of CFH Y402H and LOC387715 A69S with PCV are modified by smoking. METHODS Three hundred(More)
To evaluate whether the status of the external limiting membrane (ELM) or inner segment/outer segment junction (IS/OS) improves after intravitreal injection of ranibizumab for age-related macular degeneration (AMD). We also evaluated whether the pre-operative values of these parameters are associated with the visual prognosis. This was a hospital-based,(More)
PURPOSE To survey the prevalence of reticular pseudodrusen in late age-related macular degeneration (AMD) using multiple imaging methods, and to investigate the association between reticular pseudodrusen and polymorphisms in complement factor H (CFH) and age-related maculopathy susceptibility 2 (ARMS2) genes. DESIGN Retrospective case series. METHODS(More)
