#1
Bojan Pajic, Horace Massa, Erika N Eskina
Today there are different options for correcting presbyopia by corneal laser procedure, but all of them have their benefits and compromises. The Monovision is a pseudoaccommodation procedure which works with an anisometropy of up to 2 D. The smaller the anisometropy is the faster a neuroadaptation will be achieved. There could be a decrease of binocularity. The monovision is not well supported by all patients, thus it is important to simulate this correction by contact lenses before surgery. The PresbyLASIK is a corneal multifocal solution for presbyopia correction for emmetropic, myopic and hyperopic eyes...

BACKGROUND: Lighting is an important component of consistent, high-quality dermatologic photography. There are different types of lighting solutions available. OBJECTIVE: To evaluate currently available lighting equipment and methods suitable for procedural dermatology. MATERIALS AND METHODS: Overhead lighting, built-in camera flashes, external flash units, studio strobes, and light-emitting diode (LED) light panels were evaluated with regard to their utility for dermatologic surgeons...

PURPOSE: To determine whether the yellow filters often used for glare reduction influence retinal straylight measured in healthy eyes. SETTING: Department of Ophthalmology, Antwerp University Hospital, Edegem, Belgium. DESIGN: Prospective case series. METHODS: For each eye, the spherical equivalent (SE) was determined using an autorefractometer, followed by 5 straylight measurements taken with the compensation-comparison method...

AIM: To evaluate the positive effects of blue-violet light filtering lenses in delaying myopia and relieving asthenopia in juveniles. METHODS: Sixty ametropia juveniles (aged range, 11-15y) were randomized into two groups: the test group (30 children, 60 eyes), wearing blue-violet light filtering lenses; and the control group (30 children, 60 eyes), wearing ordinary aspherical lenses. Baseline refractive power of the affected eyes and axial length of the two groups was recorded...

Daniele Zavagno, Luca Tommasi, Bruno Laeng
Pupil diameters were recorded with an eye-tracker while participants observed cruciform patterns of gray-scale gradients that evoked illusions of enhanced brightness (glare) or of enhanced darkness. The illusions were either presented as static images or as dynamic animations which initially appeared as a pattern of filled squares that-in a few seconds-gradually changed into gradients until the patterns were identical to the static ones. Gradients could either converge toward the center, resulting in a central region of enhanced, illusory, brightness or darkness, or oriented toward each side of the screen, resulting in the perception of a peripheral ring of illusory brightness or darkness...

BACKGROUND: Few studies to date report the transcriptional response of biocontrol bacteria toward phytopathogens. In order to gain insights into the potential mechanism underlying the antagonism of the antimicrobial producing strain P. fluorescens In5 against the phytopathogens Rhizoctonia solani and Pythium aphanidermatum, global RNA sequencing was performed. METHODS: Differential gene expression profiling of P. fluorescens In5 in response to either R. solani or P...

OBJECTIVES: Recent programmatic and research efforts on addressing gaps in health systems of low-income countries increasingly see task shifting, i.e. the provision of healthcare by non-medically trained personnel, as a possible solution to increase the availability of specific services and commodities. In Kinshasa, private-sector pharmacies are the primary and preferred provider of family planning (FP) methods, and thus constitute a potential resource for expanding access to specific contraceptives...

PURPOSE: To evaluate clinical outcomes after uncomplicated microincision biaxial cataract surgery and implantation of Incise intraocular lens (IOL). METHODS: This study included 47 eyes of 29 patients (mean age 62.2 ± 8.6 years), who underwent 1.4-mm biaxial cataract surgery with implantation of the Incise IOL (Bausch and Lomb). At third month, surgically induced astigmatism (SIA) was calculated. Three, 6 and 12 months postoperatively, uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), corrected near visual acuity (CNVA) LogMAR ETDRS, spherical equivalent refraction (SER), photopic distance corrected contrast sensitivity (CS) with and without glare (85 cd/m(2)) (CSV-1000) were assessed...

Youth sporting activities have been explored as a way to impact positive personal transformation and development, glaringly demonstrated by world-wide investments in public policies, programs, and projects. We studied positive effects of participation in sports on the developmental assets of 614 adolescents (13.1 ± 1.7 years) actively engaged in extracurricular sport programs targeted at socially disadvantaged youths, from five municipalities across five states of the southern, south-eastern and north-eastern regions of Brazil...

BACKGROUND: The aim was to assess one-year changes in uncorrected and corrected contrast sensitivity (CS) and glare under scotopic conditions after accelerated cross-linking (CXL) using the 18 mW/cm(2) protocol for the treatment of progressive keratoconus and compare results with unoperated controls. METHODS: In this non-randomised clinical trial, 30 eyes were enrolled in the CXL group and 30 were assigned to the control group. Scotopic CS at spatial frequencies (SFs) of 0...

PURPOSE: Palliative care referral is primarily based on clinician judgment, contributing to highly variable access. Standardized criteria to trigger automatic referral have been proposed, but it remains unclear how best to apply them in practice. We conducted a Delphi study of international experts to identify a consensus for the use of standardized criteria to trigger automatic referral. METHODS: Sixty international experts stated their level of agreement for 14 statements regarding the use of clinician-based referral and automatic referral over two Delphi rounds...

Imaging of a weak target hidden behind a scattering medium can be significantly confounded by glare. We report a method, termed coherence gated negation (CGN), that uses destructive optical interference to suppress glare and allow improved imaging of a weak target. As a demonstration, we show that by permuting through a set range of amplitude and phase values for a reference beam interfering with the optical field from the glare and target reflection, we can suppress glare by an order of magnitude, even when the optical wavefront is highly disordered...

The glare effect (GE) is an illusion in which a white region appears self-luminous when surrounded by linearly decreasing luminance ramps. It has been shown that the magnitude of the luminosity effect can be modulated by manipulating the luminance range of the gradients. In the present study we tested the thresholds for the GE on two groups of adults: young (20-30 years old) and elderly (60-75 years old). Purpose of our perspective study was to test the possibility of transforming the GE into a test that could easily measure thresholds for luminosity and discomfort glare...

INTRODUCTION: Refractive surgery in presbyopia tends to achieve spectacle independence with minimal optical disturbances. We compared monovision to multifocality procedures regarding these outcomes. METHODS: We conducted a systematic review of published (till November 21, 2016) randomized controlled trials (RCTs) comparing any monovision to any multifocality method or comparing different monovision/multifocality methods to each other that enabled direct or indirect comparisons between particular monovision and particular multifocality procedures in presbyopic patients undergoing cataract-related or unrelated surgery in respect to spectacle independence, unaided binocular visual acuity (VA), contrast sensitivity (CS), and adverse events...

A novel bacterial strain, S66T, was isolated from eelgrass collected on the coastline of Zealand, Denmark. Polyphasic analyses involving phenotypic, phylogenetic and genomic methods were used to characterize strain S66T. The strain was Gram-reaction-negative, rod-shaped, aerobic, and displayed growth at 10-25 °C (optimum 20-25 °C) and at pH 7-9 (optimum pH 7.5). Furthermore, strain S66T grew on seaweed polysaccharides agar, agarose, porphyran, κ-carrageenan, alginate and laminarin as sole carbon sources...
