RESUMO
Purpose: Although research on teaching style preferences is available in the literature, there is limited information on the preferences of optometry teachers. The Coronavirus disease 2019 pandemic has impacted educational practices in all sectors. This study focuses on the teaching style preferences and online teaching practices of optometry teachers during the COVID-19 pandemic. Patients and Methods: The study used a case study research design and a self-administered online questionnaire and follow-up semi-structured interview for data collection. The Grasha-Riechmann teaching style inventory was used to explore the teaching style preferences (Expert, Formal Authority, Demonstrator, Facilitator and Delegator). Quantitative and qualitative data were analyzed using descriptive statistics and thematic content analysis respectively. Results: The optometry teachers were aged between 29 and 51 years (median = 45 years) and had between 3 and 25 years of teaching experience (median = 5 years). All teachers scored high in the Expert teaching style and most had scores categorized as high for the Delegator, Facilitator and Formal Authority teaching styles. The teachers reported that the initial adaptation to online teaching was difficult and challenging as they were not prepared for the rapid transition to online learning. They used various resources and materials but felt that student participation and engagement was lower in online teaching. Teachers noted that more time was needed to prepare materials for online teaching than for face-to-face teaching. Conclusion: Optometry teachers adopted a multidimensional approach preferring the different teaching styles to varying degrees. Teachers noted challenges with the initial transition and adaptation to online teaching and used a combination of resources to support student learning.
RESUMO
Keratoconus (KC) is a progressive, asymmetrical corneal disease, characterized by stromal thinning that leads to distortion, causing vision loss. The visual loss is secondary to corneal scarring, irregular astigmatism, and myopia. The prevalence of KC has been reported to differ in different parts of the world. The study aimed to determine the prevalence and profile of patients with KC presenting to a provincial hospital in KwaZulu-Natal, South Africa. A retrospective study design was used to review 412 clinical records of patients attending the McCord Provincial Eye Hospital (MPEH) during a five-year period (2016-2020). Data on age, race, refraction, clinical profile, treatment plan, and diagnosis were ascertained. The prevalence of KC in MPEH was found to be 13.7% with a mean age of 24.7±7.94 years. Black African and females had a higher frequency of KC compared to males and other ethnic groups. Most of the patients presented with a severe stage of KC and referral was the most common management. Central corneal thinning and Munson's sign were the most prevalent clinical signs. There was no statistically significant difference between the worse and better eye when comparing the clinical signs. The prevalence and clinical profile of patients with KC in this study was similar to that reported by previous studies and more in Blacks and females. Population based epidemiological studies are needed to determine the prevalence of KC in South Africa to enable early clinical interventions.
