In the first of three studies, children (aged 8 to 14 years) were found to perform worse than young and middle-aged adults in unprompted identification of doors, with average performance much like that of elderly adults. Comparisons on other tasks, specifically odor threshold, prompted odor identification, and object naming (Boston Naming Test), across the(More)
Two experiments are reported in which the perceptual interactions between oral pungency, evoked by CO2, and the taste of each of four tastants--sucrose (sweet), quinine sulfate (bitter), sodium chloride (salty), and tartaric acid (sour)--were explored. In experiment 1 the effect of three concentrations of each tastant on the stimulus-response function for(More)
EDITORIAL It is known that pseudophakia is a very frequent condition in ophthalmology. The visual benefit obtained after a cataracts operation can diminish in time due to the progressive development of a posterior capsule opacification (PCO). Even though surgical techniques and the design and materials of intra-ocular lenses have been continuously modified,(More)
PURPOSE To compare central corneal thickness (CCT) results measured by Fourier-domain optical coherence tomography (FD-OCT) and ultrasound pachymetry (USP) in glaucomatous eyes. METHODS In this prospective, observational cross-sectional study, 80 eyes of 80 patients with primary open-angle glaucoma (POAG) and no other ocular abnormality were selected: 28(More)
In the present study, we investigated taste-taste, taste-vehicle, and simultaneous taste-vehicle-taste mixtures. Subjects made estimates of the sweetness and bitterness of 27 stimuli. Sucrose (292, 585, and 1170 mM), caffeine (13, 26, and 52 mM), and binary mixtures of low (292-13 mM), middle (585-26 mM), and high (1170-52 mM) levels of both components were(More)
We observed that taste detection thresholds for caffeine (CAF) are elevated in habitual CAF users relative to nonusers. A series of experiments were carried out to explore that relationship and assess the influences of salivary CAF and acute vs. chronic CAF ingestion. A significant correlation between CAF ingestion and taste threshold was noted in two(More)
PURPOSE This study was designed to evaluate the effect of antioxidant supplementation on diabetic retinopathy (DR) over a 5-year follow-up period. To our knowledge, this is the first such clinical trial performed. METHODS We recruited 105 type 2 diabetic patients with nonproliferative DR. A complete ophthalmic checkup and a plasma determination of(More)
OBJECTIVE To determine the values of, and study the relationships among, central corneal thickness (CCT), intraocular pressure (IOP), and degree of myopia (DM) in an adult myopic population aged 20 to 40 years in Almeria (southeast Spain). To our knowledge this is first study of this kind in this region. METHODS An observational, descriptive,(More)
PURPOSE To evaluate the effect of oral antioxidant supplementation (OAS) on primary open-angle glaucoma (POAG) over a 2-year follow-up period. PATIENTS AND METHODS In this open-label, randomized controlled trial, 117 eyes of 117 patients with mild or moderate POAG and intraocular pressure under control with topical antiglaucoma medications were recruited(More)
