PURPOSE To evaluate the safety and efficacy of switching from bevacizumab to ranibizumab in patients with neovascular age-related macular degeneration. METHODS Retrospective study of patients with neovascular age-related macular degeneration initially treated with bevacizumab and switched to ranibizumab. Visual acuity and central retinal thickness (CRT)(More)
Let Dd,k denote the discriminant variety of degree d polynomials in one variable with at least one of its roots being of multiplicity ≥ k. We prove that the tangent cones to Dd,k span Dd,k−1 thus, revealing an extreme ruled nature of these varieties. The combinatorics of the web of affine tangent spaces to Dd,k in Dd,k−1 is directly linked to the root(More)
We present new evidence about the long-run relationship between state capacity and economic performance in Europe, the birthplace of modern economic growth. Our database is novel and spans 11 countries and 4 centuries from the Old Regime to World War I. We argue that national governments undertook two political transformations over this period: fiscal(More)
We present new evidence about the long-term links between state capacity and economic performance. Our database is novel and spans 11 countries and 4 centuries in Europe, the birthplace of modern economic growth. A dynamic simultaneous equation panel model indicates that the performance effects of states with modern extractive and productive capabilities(More)
Abnormal angiogenesis is the hallmark feature of retinopathy of prematurity (ROP), and contributes to the severe visual loss that accompanies this disease. Thalidomide is a well-known anti-angiogenic drug. We tested the assumption that injection of intraperitoneal thalidomide could reduce the severity of oxygen-induced retinopathy (OIR) in a mouse model.(More)
IMPORTANCE Assessing the effect of ocriplasmin availability on the management of full-thickness macular holes (MHs) is important for vitreoretinal surgeons and their patients. Such an assessment can indicate whether the use of ocriplasmin will bring a paradigm shift in treating MHs or will be just an additional option relevant to a small group of patients.(More)
OBJECTIVE To assess the outcome and risk factors for failure of pneumatic retinopexy (PR) in eyes with primary rhegmatogenous retinal detachment (RRD). METHODS Data of patients who underwent PR for the repair of primary RRD, from January 1, 2000, through June 30, 2011, were retrieved from medical records and retrospectively analyzed. Patients with a(More)
OBJECTIVE The objective of the study was to compare the efficacy and safety of topical dexamethasone sodium phosphate 0.1% (Sterodex) to diclofenac sodium 0.1% (Voltaren Ophthalmic) after combined phacotrabeculectomy with mitomycin C. METHODS This prospective, randomized, double-masked clinical trial includes 42 patients with glaucoma and cataract who(More)
The European Society of Cataract & Refractive Surgeons (ESCRS) study reported a decrease in endophthalmitis rates from 0.34 % to 0.08 % with the use of intracameral cefuroxime. The purpose of this study was to compare the endophthalmitis rates before and after the introduction of intracameral cefuroxime (ICC) routinely at the end of cataract surgery. A(More)
