The effectiveness of smartphone ophthalmoscope compared to direct ophthalmoscope as a teaching tool

Abstract

Introduction: The direct ophthalmoscope is a standard tool for fundus examination but is underutilised in practice due to technical difficulties. Although the smartphone ophthalmoscope has been demonstrated to improve fundus abnormality detection, there are limited studies assessing its utility as a teaching tool for fundus examination in Southeast Asian medical schools. This study explored the perception of medical students' toward using a smartphone ophthalmoscope for fundus examination and compared their abilities to diagnose common fundal abnormalities using smartphone ophthalmoscope against direct ophthalmoscope. Methods: Sixty-nine Year-4 undergraduate medical students participated in the study. Their competencies in using direct ophthalmoscope and smartphone ophthalmoscope for fundus examination on manikins with ocular abnormalities were formatively assessed. The scores were analysed using the SPSS statistical software. Their perceptions on the use of smartphone ophthalmoscopes for fundus examination were obtained using a questionnaire. Results: The students' competency assessment scores using the smartphone ophthalmoscope were significantly higher than those using the direct ophthalmoscope. A significantly higher percentage of them correctly diagnosed fundus abnormalities using the smartphone ophthalmoscope. They were confident in detecting fundus abnormalities using the smartphone ophthalmoscope and appreciated the comfortable working distance, ease of use and collaborative learning. More than 90% of them were of the view that smartphone ophthalmoscopes should be included in the undergraduate medical curriculum. Conclusion: Undergraduate medical students performed better in fundus examination on manikins with ocular abnormalities using smartphone ophthalmoscope compared to direct ophthalmoscope. Their positive perceptions toward smartphone ophthalmoscope support its use as a supplementary teaching tool in undergraduate medical curriculum.
