PURPOSE We determined if the Bruch's membrane opening (BMO) location changes over time in healthy eyes and eyes with progressing glaucoma, and validated an automated segmentation algorithm for identifying the BMO in Cirrus high-definition coherence tomography (HD-OCT) images. METHODS We followed 95 eyes (35 progressing glaucoma and 60 healthy) for an average of 3.7 ± 1.1 years. A stable group...

PURPOSE This study was performed to evaluate the structure-function relationship between Bruch's membrane opening (BMO) parameters of the optic nerve head (ONH) and visual field (VF) sensitivity. METHODS Forty-six right eyes of 46 patients with open-angle glaucoma (OAG) in the patient group and 12 right eyes in the control group were included. Standard automated perimetry (SAP) and spectral-d...

Purpose: To evaluate the diagnostic value of retinal nerve fiber layer-to-disc ratio (RDR) compared to established parameters including layer thickness (RNFLT), Bruch membrane opening-minimum rim width (BMO-MRW), and area (BMO-MRA) for differentiating between open angle glaucoma (OAG) nonarteritic anterior ischemic optic neuropathy (NAION).Methods: This retrospective study included 23 disc size...

In this paper we show that the theory of Hankel operators in the torus T , for d > 1, presents striking differences with that on the circle T, starting with bounded Hankel operators with no bounded symbols. Such differences are circumvented here by replacing the space of symbols L∞(T) by BMOr(T), a subspace of product BMO, and the singular numbers of Hankel operators by so-called sigma numbers....

PURPOSE To quantify and characterize the difference between automated and manual segmentation of optic nerve head structures with spectral-domain optical coherence tomography (SD-OCT). METHODS Optic nerve head radial scans in 107 glaucoma patients and 48 healthy controls were conducted with SD-OCT. Independent segmentations of the internal limiting membrane (ILM) and Bruch's membrane opening ...

BACKGROUND AND OBJECTIVE To investigate and compare the false-positive (FP) diagnostic classification of the Bruch's membrane opening - minimum rim width (BMO-MRW) and retinal nerve fiber layer (RNFL) thickness in healthy eyes with tilted optic disc. MATERIALS AND METHODS Fifty healthy eyes of 30 participants with tilted optic disc underwent BMO-MRW and RNFL scanning using Spectralis and macu...

We show that Zorboska’s criterion for compactness of Toeplitz operators with BMO symbols on the Bergman space of the unit disc holds, by a different proof, for the Segal-Bargmann space of Gaussian square-integrable entire functions on Cn. We establish some basic properties of BMO for p ≥ 1 and complete the characterization of bounded and compact Toeplitz operators with BMO symbols. Via the Barg...

We study in this article the solutions of the Navier-Stokes equations, with an initial data in ∂BMO. For u|t=0 in the closure of the Schwartz class, we obtain the existence and uniqueness of a global solution, and an estimate on its norm in ∂BMO.

Despite the use of newer and more powerful calendar and collaboration tools, the task of scheduling and rescheduling meetings is very time consuming for busy professionals, especially for highly mobile people. Research projects and commercial calendar products have worked since the early 1990s on implementing intelligent meeting organizers to automate meeting scheduling. However, automated sche...
