Identifying and Exploring the Cognitive Nature of Threshold Concepts in Pharmacology to Improve Medical Students' Learning.

Pharmacology is a fundamental healthcare discipline, but it can be difficult and counterintuitive for learners to learn. Navigation toward understanding pharmacology can be troublesome, but once the threshold to comprehension is crossed, learners can experience a transformative shift in their ways of thinking and practicing. We conducted an in-depth examination of threshold concepts within pharmacology, aiming to identify and prioritize their learning to improve the medical curriculum and enhance medical treatment and patient safety.

Vision-Related Quality of Life Among Diabetic Retinopathy Patients in a Hospital-Based Population in the Sultanate of Oman.

Background: The global prevalence of diabetic retinopathy (DR) among individuals with diabetes is 22.27%. This highlights the likelihood of developing burden of retinopathy within the at risk population and can have a detrimental impact on an individual's quality of life (QoL).

Profile of contact lens prescribing in GCC countries.

Purpose: This study aimed to report the pattern of contact lens prescribing from the Gulf Cooperation Council (GCC) countries.

Methods: Optometrists in the GCC region were contacted to participate in a web-based survey hosted on Qualtrics XM (Provo, Utah, USA). The survey methodology was adapted from the International Contact Lens Prescribing Consortium, and participants were asked to report their last five lens fits.

Exploring the use of metacognitive monitoring cues following a diagram completion intervention.

Studying texts constitutes a significant part of student learning in health professions education. Key to learning from text is the ability to effectively monitor one's own cognitive performance and take appropriate regulatory steps for improvement. Inferential cues generated during a learning experience typically guide this monitoring process.

Twelve tips for applying the think-aloud method to capture cognitive processes.

The think-aloud method is an established technique for studying human thought (cognitive) processes. Problem-solving and decision-making are essential skills for medical professionals, and the cognitive processes underlying these skills are complex. Studying these thought processes would enable educators, clinicians, and researchers to modify or refine their approaches and interventions.

Barriers and Perception Towards Spectacle Wear among a Student Population of University of Buraimi, Oman.

Objectives: The study aimed to evaluate the barriers and perceptions towards spectacle wear among the student population of the University of Buraimi, Oman.

Methods: A descriptive, questionnaire-based and cross-sectional study was conducted between December 2017 and May 2018. Ophthalmic examination and a standard spectacle prescription protocol were used to identify those with inappropriate spectacle coverage.

Concept Animation - a potential instructional scaffolding.

This article was migrated. The article was marked as recommended. Concept animation - the graphical array of pictures accompanied by text as speech balloons, can help to improve learner's comprehension from basic to advanced levels concepts.

Trend of soft contact lens prescribing in an optometry centre in India: a 6-year analysis.

This six-year retrospective longitudinal study was conducted to examine the changes in the pattern of prescribing soft contact lenses in an optometry centre located in a University in South India. Details regarding the type of lenses, lens material, wearing pattern and the clinical diagnoses were analyzed from January 2006 to December 2011. A total of 1273 soft contact lens fits (n=1273) were analyzed.

Contact lens prescribing pattern in India--2011.

Purpose: To understand the pattern of prescribing contact lenses (CL) among Indian practitioners.

Methods: Survey forms were sent to 257 practitioners across the country to collect information about their last 10 CL fits, location and type of practice, years of experience and educational qualification. A logistic regression analysis was performed to determine any association of various factors to the lens fitting pattern and chi-square test was used to compare proportions.

Reliability of a modified logMAR distant visual acuity chart for routine clinical use.

Background/aim: Acuity charts that follow the principle of logarithmic size progression (logMAR charts) are considered to be the gold standard for the assessment of distant vision. But it is not well accepted for routine eye examinations due to increased testing time and the complexity of scoring. This study was designed to check whether a modified logMAR chart with three optotypes would provide a reliable acuity assessment compared to standard logMAR charts for routine eye examination.

Contact lens compliance among a group of young, university-based lens users in South India.

Purpose: To investigate the rate of compliance with the soft contact lens care and maintenance procedures with a focus on contact lens wearing habits, cleaning and disinfecting procedures, and maintenance of lens care accessories in a group of young, university-based contact lens wearers

Methods: Two hundred and sixteen young soft contact lens wearers with an age range of 18-22 years were selected conveniently from the student population of Manipal University, Manipal, India. After receiving informed consent from the participants, their level of compliance with contact lenses was assessed using a questionnaire.

Results: The mean (±SD) age of the participants was 21.

The effect of smoking on the ocular surface and the precorneal tear film.

Background: Smoking, both active and passive, creates a plethora of health-related problems, which primarily affect the cardiovascular and respiratory systems. There is very little evidence on the effects of tobacco smoke on the eye, especially regarding anterior ocular surface related pathology. This study was undertaken to determine the effects of smoking on the ocular surface and the tear film in smokers.

Efficacy of a remote based computerised visual acuity measurement.

Aim: To determine the efficacy of a remotely operated computer-based logarithmic (logMAR) visual acuity chart.

Methods: Visual acuity was tested using a laptop or computer-based logMAR chart (COMPlog) for all subjects by two different methods. The methods differed by the physical presence and absence (remote) of an optometrist and in the mode of instructions provided.
