PURPOSE To investigate the effect of 3rd-order aberrations on human vision. SETTING Grupo de Ciencias de la Visión, University of Murcia, Murcia, Spain. METHODS The 3rd-order aberrations coma and trefoil were induced with purpose-designed soft contact lenses, 3 inducing coma (low [0.05 microm], medium [0.13 microm], high [1.03 microm]) and 3 inducing(More)
PURPOSE To examine the relationship between relative accommodation and general binocular disorders and to establish their importance in the diagnosis of these anomalies. METHODS We analyzed data of negative relative accommodation (NRA) and positive relative accommodation (PRA) in 69 patients with nonstrabismic binocular anomalies. RESULTS Statistical(More)
A single colony of the non-native grass Poa pratensis L., which was introduced inadvertently to Cierva Point, Antarctic Peninsula, during the 1954–1955 season, was still present during a survey in February 2012, making it the longest surviving non-native vascular plant colony known in Antarctica. Since 1991, the grass cover has roughly tripled in size, with(More)
Gastroesophageal reflux disease (GERD) has been related with certain psychological dimensions. The influence of mood, emotional intelligence, and perceived quality of life on clinical symptoms and outcome of antireflux surgery was evaluated in GERD patients with and without hiatal hernia. The study included 61 patients who were diagnosed with GERD between(More)
PURPOSE To determine which are the most sensitive tests, together with accommodative amplitude, to classify accommodative insufficiency (Al), we analyzed the relation between monocular estimated method (MEM) dynamic retinoscopy, monocular and binocular accommodative facility (MAF, BAF), and positive relative accommodation (PRA) with or without the presence(More)
Chemiluminescence (CL)-based detection has become in the last years quite a useful detecting tool in liquid chromatography (HPLC) due to its simplicity, low cost and high sensitivity and selectivity, and the development in instrumentation. Minimal instrumentation is required and no external light source is needed; thus, the optical system is quite simple.(More)
This study assesses the proportion of patients presenting with nonvisceral chronic abdominal pain who have thoracic disk herniation as a possible cause. We designed a descriptive transversal study of patients attending our offices between February 2009 and October 2010, with a complaint of chronic abdominal pain of suspected abdominal wall source (positive(More)
A new analytical method based on capillary zone electrophoresis-tandem mass spectrometry (CZE-MS/MS) is proposed and validated for the identification and simultaneous quantification of eight quinolones for veterinary use in bovine raw milk. The studied quinolones include danofloxacin, sarafloxacin, ciprofloxacin, marbofloxacin, enrofloxacin, difloxacin,(More)
PURPOSE To investigate the relationship between accommodation and the optical aberrations of the whole human eye, as a function of age. METHODS Sixty healthy subjects with spherical ametropia in the range +/-3 D, astigmatism less than 1 D, corrected visual acuity of 20/18 or better, and normal findings in an ophthalmic examination were enrolled. Subjects(More)
PURPOSE We evaluate the effect of pupil size on objectively measured amplitude of accommodation (AA). METHODS Pupil diameter and wavefront aberrometry were obtained in 15 eyes when stimulus swept across the range of clear vision in steps of 0.5 diopters. Wavefront refraction techniques were used to compute objective AA as the maximum refractive change.(More)
