Monocular and binocular vision was assessed in patients with glaucoma (n = 21), in patients with ocular hypertension (n = 20), and in age-matched visual control subjects (n = 20) using three tests: color vision with the Lanthony Desaturated D-15 test, low spatial frequency contrast sensitivity with the Pelli-Robson chart, and stereoacuity with the RANDOT(More)
During apoptosis, Bax-type proteins permeabilize the outer mitochondrial membrane to release intermembrane apoptogenic factors into the cytosol via a poorly understood mechanism. We have proposed that Bax and DeltaN76Bcl-x(L) (the Bax-like cleavage fragment of Bcl-x(L)) function by forming pores that are at least partially composed of lipids (lipidic pore(More)
BACKGROUND Intraocular pressure (IOP) measurements obtained with five commercially available portable tonometers (Keeler Pulsair 2000, Tomey Pro-Ton, Tono-Pen XL, Perkins, and Shiotz) were compared to IOPs measured with a Goldmann tonometer in order to predict whether instrument accuracy justified substitution of a portable instrument for the Goldmann in(More)
OBJECTIVE The Farnsworth-Munsell 100-Hue, the Farnsworth D-15, and the L'Anthony D-15 desaturated color tests were administered to patients with glaucoma to determine whether the D-15 or D-15 desaturated color tests could be used to predict performance on the 100-Hue test in clinical populations. METHODS The three color tests were administered to 35(More)
This is an initial report from a study to determine the safety and efficacy of an implant placed within the sclera to relieve elevated intraocular pressure (IOP). It describes the first eight patients to receive the implant. Intraocular pressure and pneumotonometry were evaluated preoperatively and postoperatively for one year. In five patients, IOP(More)
We investigate the dynamics of liquid-liquid phase separation confined in a charged concentric cylindrical geometry. Two main time scales characterize the non-equilibrium interface behavior: (1) the lag time t(L) for forming an interface, and (2) the relaxation time to equilibrium. We find that t(L) increases as parameters (temperature, bulk composition,(More)
We deduce the mixing-demixing phase diagram for binary liquid mixtures in an electric field for various electrode geometries and arbitrary constitutive relation for the dielectric constant. By focusing on the behavior of the liquid-liquid interface, we produce simple analytic expressions for the dependence of the interface location on experimental(More)
Spatially non-uniform electric fields can phase separate initially homogeneous mixtures of liquids. Here, we investigate the dynamics of phase separation using a modified Cahn-Hilliard equation and find three kinetically distinct regimes in the phase diagram: (1) discontinuous and (2) continuous interface formation kinetics and (3) a metastable state.
