Field experiments with manipulations of natural enemies of plant-feeding insects may show how a diverse enemy group ensures an important ecosystem function such as naturally occurring biological pest control. We studied cereal aphid populations in winter wheat under experimentally reduced densities of: (i) ground-dwelling generalist predators (mostly(More)
PURPOSE To evaluate eyes with age-related macular degeneration and high-risk characteristics for choroidal neovascularization (CNV) with optical coherence tomographic (OCT) angiography to determine whether earlier detection of CNV is possible. METHODS Eyes with drusen, pigmentary changes, and with CNV in the fellow eye were scanned with a 70-kHz spectral(More)
PURPOSE To report on a series of white patients in the United States with polypoidal choroidal vasculopathy (PCV). METHODS This is a retrospective chart review of 27 patients at a single center with PCV. RESULTS The mean age was 74.3 with 48% being male. The most common presenting diagnosis was exudative age-related macular degeneration in 59%, and it(More)
PURPOSE To describe the optical coherence tomography angiography features of diabetic retinopathy. METHODS Using a 70 kHz optical coherence tomography and the split-spectrum amplitude decorrelation angiography algorithm, 6 mm × 6 mm 3-dimensional angiograms of the macula of 4 patients with diabetic retinopathy were obtained and compared with fluorescein(More)
Typical arguments for the use of agent technology in business information systems rely on the heterogeneity of the information landscape, the physical distribution of its components, and the overall complexity of such systems. In the domain of IT support for Knowledge Management, these claims for agent systems typically also hold, but additionally are(More)
PURPOSE To report the change in visual acuity and central retinal thickness by optical coherence tomography (OCT) after intravitreal injections of bevacizumab for the treatment of neovascular age-related macular degeneration (AMD). METHODS A retrospective case series in a university-based practice evaluated patients with subfoveal choroidal(More)
Diabetic macular edema (DME) and choroidal neovascularization (CNV) associated with age-related macular degeneration (AMD) are the leading causes of vision loss in the industrialized world. The mainstay of treatment for both conditions has been thermal laser photocoagulation, while there have been recent advances in the treatment of CNV using photodynamic(More)
OBJECTIVE Infliximab, a monoclonal antibody against tumor necrosis factor alpha, is approved by the US Food and Drug Administration for treatment of numerous autoimmune disorders. We conducted a prospective, open-label phase 2 clinical trial to assess the effectiveness of infliximab in treating refractory autoimmune uveitis. METHODS We prospectively(More)
OBJECTIVE To describe grading procedures for optical coherence tomographic (OCT) images of participants in the Standard Care vs Corticosteroid for Retinal Vein Occlusion (SCORE) Study. METHODS Optical coherence tomograms were taken at clinical sites with the Stratus OCT using fast macular and crosshair scan protocols. Paper prints of images were evaluated(More)
