OBJECTIVES To assess and compare contrast sensitivity function in the previously amblyopic and non-amblyopic "normal" eyes of patients with microtropia and anisometropia who achieved 20/20 visual acuity after occlusion therapy. MATERIALS AND METHODS Contrast sensitivity was tested monocularly on both eyes of 34 successfully treated microtropic and 15 anisometropic subjects (visual acuity 20/2...

BACKGROUND Contrast sensitivity measurement in UK clinical practice is most commonly performed with the Pelli-Robson chart. AIMS To compare the repeatability of two new contrast sensitivity charts and to measure their agreement with the Pelli-Robson charts. METHOD Contrast sensitivity was measured monocularly using two versions of the Mars letter contrast sensitivity chart, two presentation...

PURPOSE The Mars Letter Contrast Sensitivity Test (initially known as the Lighthouse Letter Contrast Sensitivity Test) is similar in design to the Pelli-Robson Test but may offer several advantages. This study evaluates the repeatability of the Mars test and its agreement with the Pelli-Robson test in normal and low-vision subjects. METHODS Fifty-four subjects were tested (age 22-86 years), i...

conclusions according to these findings, antibiotic-resistance patterns have changed, and vancomycin resistance, especially among e. faecium, is rising because of nosocomial infections. consequently, it has become a serious subject for patients admitted into a hospital. results a total of 53 enterococci were isolated from clinical samples of blood, urine, wounds, sputum, and cerebrospinal fluid...

background and objectives: methicillin-resistant staphylococcus aureus (mrsa) is a well-known pathogen with a worldwide distribution. given the increasing rate of mrsa infections, implementing of reliable, accurate and rapid testing for diagnosis of mrsa is necessary. the aim of this study was to compare four diagnostic methods for detection of mrsa isolates. materials and methods: from decembe...

conclusions: silver nanoparticles showed great antibacterial effectiveness on four important foodborne pathogens. therefore, ag nps could be a good alternative for cleaning and disinfection of equipment and surfaces in food-related environments. results: the mic values of ag nps against tested pathogens were in the range of 3.12-6.25 µg/ml. while listeria monocytogenes showed the mic value of 6...

BACKGROUND The purpose of this study was to evaluate the efficacy of neural vision therapy, also termed perceptual vision therapy, in enhancing best corrected visual acuity (BCVA) and contrast sensitivity function in amblyopic patients. METHODS This prospective study enrolled 99 subjects previously diagnosed with unilateral hypermetropic amblyopia aged 9-50 years. The subjects were divided in...
