AIMS To compare tritan colour contrast sensitivity (CCS), without and with glare, in patients with refractive multifocal intraocular lenses (IOLs) and with monofocal intraocular lenses. METHODS Tritan CCS was determined (Moorfields Vision System, CH Electronics) in 15 eyes (14 patients, 75.7 (+/-6.6) years) with a refractive multifocal IOL (Allergan SA 40N) and in 11 eyes (10 patients, 73.7 (...

OBJECTIVE The present study aimed to compare outcomes of cricopharyngeal myotomy (CPM) in patients with documented cricopharyngeal dysfunction (CPD) and those in whom the diagnosis is complex or in doubt. MATERIALS AND METHODS Retrospective comparative study of all patients undergoing CPM between 2001 and 2010 at a single UK centre. Patients were classified as having either CPD (n = 15) or no...

BACKGROUND Health care professionals have been striving to maintain their competence to deliver the best quality of service. This study intended to determine involvement in continuing professional development of community pharmacists in Gondar, Northwest Ethiopia. METHODS About 46 community pharmacists, each from a different setting, were interviewed using structured questionnaire. Data were ...

Objective To investigate the views and assess motivation, attitudes of pharmacists in Lebanon towards mandatory continuous education (CE), its transition to Continuous Professional Development (CPD), and identify barriers to participation in CPD. Methods A cross-sectional observational study, conducted between February and May 2017, enrolled 591 pharmacists. The questionnaire used in this stu...

Natural marine phytoplankton assemblages from Bahía Bustamante (Chubut, Argentina, 45 degrees S, 66.5 degrees W), mainly consisting of cells in the picoplankton size range (0.2-2 microm), were exposed to various UVBR (280-315 nm) and UVAR (315-400 nm) regimes in order to follow wavelength-dependent patterns of cyclobutane pyrimidine dimer (CPD) induction and repair. Simultaneously, UVR induced ...

Kehrer [Spatial Vision 2 (1987) 247] found that texture discrimination performance sometimes peaks in the parafovea rather than at the fovea, and he referred to this phenomenon as the central performance drop (CPD). Kehrer used a backward mask to limit performance and Morikawa [Vision Res. 40 (2000) 3517] argued that in some cases the temporal aspects of the backward mask may be critical to the...

Both visual acuity (VA) and contrast sensitivity (CS) are important parameters for measuring visual function. In this research, we investigated the CS of patients with ametropic or anisometropic amblyopia, whose corrected visual acuity (CVA) recovered to 1.0. Fifty-five cases with amblyopia and 22 control cases with a normal visual acuity of 1.0 were enrolled. The CS of the patients whose ametr...
