The advantages are its relatively low cost, ease of portability and large 15× magnified view of the fundus. However, with the widespread use of binocular indirect ophthalmoscopes in specialist ophthalmic practices, the use of the direct ophthalmoscope is mostly limited to non-ophthalmic physicians to identify ophthalmic manifestations of vascular or neurological emergencies in emergency rooms, intensive care units and medical clinics [1]. For diabetic retinopathy screening in community general practices, the use of digital fundus photography since the 1990s, with its much more practical wide 45° field of view, has mostly supplanted examination by direct ophthalmoscope. Despite direct ophthalmoscopy still being taught in medical schools around the world, it is important to note the steep learning curve associated with its use. Often, when using the direct ophthalmoscope, medical students struggle to achieve a reasonable view of the fundus and thus are much less competent on picking up and interpreting salient signs of neurological or vascular emergencies [2]. Even with the introduction of new educational tools in the last decade, including simulators (Eyesi; VRmagic, Mannheim, Germany), there remains a general lack of confidence in direct ophthalmoscope use among non-ophthalmic physicians worldwide [3].\nThis article is based on previously conducted studies and does not contain any studies with human participants or animals performed by any of the authors.\nThe coronavirus disease 2019 (COVID-19) pandemic has posed significant challenges to medical education and clinical care [4]. During this panademic period, we identified two main issues with direct ophthalmoscopy. First, as medical educators, we found it extremely challenging to teach direct ophthalmoscopy to medical students through videoconferencing platforms for a number of reasons, all of which we have outlined the reasons in an earlier publication [5]. In particular, learning to use a direct ophthalmoscope requires a substitute patient to practice on; when mandatory social distancing measures are in place, this is difficult to achieve. Furthermore, and more importantly, the examination is performed with the examiner’s own face in close proximity to the patient, requiring the examiner’s own cheek to be touching the patient’s cheek. Our group has recently reported, using ex vivo experiments, that the human conjunctiva is a potential major gateway for the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) to enter the body [6]. This is a significant infection control issue in the context of a highly virulent and transmissible disease. While we do not believe that the pandemic will be the sole reason for the obsolescence of the direct ophthalmoscope, it presents medical educators and clinicians worldwide with the opportunity to identify better long-term solutions for fundus examination by non-ophthalmic physicians.\nThe recent introduction of affordable cameras for non-mydriatic fundus photography, both portable and fixed, such as the Visuscout 100, a mobile fundus camera produced by Carl Zeiss AG (Oberkochen, Germany), has provided a unique alternative in this panademic climate. Such devices allow for accurate, instant wide-field fundus image acquisition by the bedside or in clinics. Rather than spend most of the time and effort on actually finding the fundus, the examiner can be properly trained in fundus photo interpretation of common ophthalmic signs of systemic disease. There are further advantages to this method. Firstly, proper documentation and transfer of fundus findings can be made with the images [7]. Alternatively, the images can be saved for a formal remote evaluation by an ophthalmologist for medico-legal reasons. Newer fundus imaging devices (for example, the Optos Silverstone [Optos, Dunfermline, UK]) produce a wide 200° field of view and come with integrated swept-source optical coherence tomography, thus allowing for state-of-the-art multimodality imaging of the retina and choroid. Furthermore, with the development of deep-learning systems for fundus pattern recognition, the images can be screened by artificial intelligence programs with high accuracy and efficiency. An example of this is the recent validation of an artificial intelligence system in screening for papilledema in ocular fundus photographs [8]. With the COVID-19 pandemic forcing us to re-examine the way we teach ophthalmic skills to medical students, we believe this is one major area that should undergo some long overdue changes that can provide long-lasting benefits to clinical care. In the long run, the pandemic may expedite a shift in focus that will better prepare our medical students to work in an environment where tele-medicine and artificial intelligence become increasingly important aspects of healthcare. Despite these changes, it is important to remember that a systematic approach to patient examination will never be obsolete. At all times we need to consider the whole patient when evaluating the back of the eye."}
