OBJECTIVE To determine the visual outcome of laser treatment in diabetic retinopathy. DESIGN Prospective, non-comparative case series. MATERIALS AND METHODS A total of 80 eyes of 50 patients with diabetic retinopathy in different stages were photocoagulated using diode green laser. Focal laser only was given in 46 eyes and pan retinal photocoagulation only was given in 29 eyes while 3 eyes ...

PURPOSE To determine week 52 efficacy and safety outcomes in eyes with macular edema after branch retinal vein occlusion (BRVO) treated with 2 mg intravitreal aflibercept injection (IAI) compared with grid laser. DESIGN VIBRANT was a double-masked, randomized, phase 3 trial. PARTICIPANTS Eyes randomized and treated in VIBRANT were followed to week 52. METHODS In the IAI group, eyes receiv...

Grid systems have been put to remarkable use in recent years. Finding planets, rendering multi-million dollar movies, and helping to understand disease are just some of the examples grid systems have been used for. With business turning to towards using grid systems and looking to make them global mechanisms for service delivery, they are nicely poised to be an exciting future prospect. However...

We present a parallel Cartesian-grid-based time-dependent Schrödinger equation (TDSE) solver for modeling laser–atom interactions. It can simulate the single-electron dynamics of atoms in arbitrary time-dependent vector potentials.We use a split-operatormethod combinedwith fast Fourier transforms (FFT), on a three-dimensional (3D) Cartesian grid. Parallelization is realized using a 2D decomposi...

a time-of-flight mass spectrometer (tof-ms) developed in our laboratory at isfahan university of technology is described here. the tof-ms instrument uses laser as the ionization source which provides an opportunity to investigate the ions formed in laser ablation or desorption. the tof-ms has an ionization chamber containing an accelerator and an ion lens to focus the ions into a one meter line...

In recent decades, there has been a revolution in energy-based treatment options for skin scarring, rejuvenation, and tightening. One of the most promising developments has been the introduction of fractional photothermolysis, developed by Anderson and Manstein in 2004. Fractionated systems deliver laser energy in a grid-like pattern, creating microscopic columns of ablative and/or coagulative ...

Laser Profiler (LP) data from aerial laser surveys have been increasingly used as topographical inputs to numerical simulations of flooding and inundation in river basins. LP data has great potential for reproducing topography, but its effective usage has not yet been fully established. In this study, flooding and inundation are simulated numerically using LP data for the Jobaru River basin of ...
