AIM: To explore the neuro-ophthalmological characteristics of acute macular neuroretinopathy(AMN)after SARS-CoV-2 infection.METHODS: A total of 8 patients(14 eyes), including 6 females and 2 males, who were diagnosed with AMN in the neuro-ophthalmology department of Xi'an No.1 Hospital(The First Affiliated Hospital of Northwest University)from December 27, 2022 to February 1, 2023 were included in the study. All patients had a history of SARS-CoV-2 infection before the disease, and the results of best corrected visual acuity(BCVA), non-contact indirect intraocular pressure measurement, fundus color photography, near infrared(IR), spectral-domain optical coherence tomography(SD-OCT), OCT angiography(OCTA), fundus fluorescein angiography(FFA), indocyanine green angiography(ICGA), visual field, visual evoked potential(VEP), and electroretinogram(ERG)were collected. Furthermore, the neuro-opthalmology characteristics of the included patients were analyzed and summarized.RESULTS: The included 8 patients aged from 20 to 43, with an average age of(30±6.63)years old. The patients had a history of SARS-CoV-2 infection 3 to 11(mean 5±3.51)d before the disease, and 6 out of 8 patients developed visual symptoms within 5 d of infection with SARS-CoV-2, with manifestated with decreased vision or visual scotoma. The visual acuity varied from 0.08 to 1.0, with visual field defect characterized by central, paracentral or peripheral scotoma. VEP showed prolongation latency of P100 or P2, and ERG revealed impaired function of retinal photoreceptor cell. In the early stage of the disease, the size and shape of early visual acuity, visual field, and extraretinal lesions in patients with AMN associated with SARS-CoV-2 infection may not match, and the lower the visual acuity, the later the VEP peaks.CONCLUSION: The neuro-ophthalmic features of SARS-CoV-2 infection-associated AMN require the attention of clinicians.

ABSTRACT Medical specialties have recognized that breaking bad news assists clinical practice by mitigating the impact of difficult conversations. This scenario also encourages various studies on breaking bad news in ophthalmology since certain ocular diagnoses can be considered bad news. Thus, the objective is to review the scientific literature on breaking bad news in ophthalmology. The literature databases like MEDLINE/PUBMED, EMBASE, LILACS, SCOPUS, COCHRANE, and SCIELO, were screened for related research publications. Two independent reviewers read all the articles and short-listed the most relevant ones. Seven articles, in the formats of original article, review, editorial, oral communication, and correspondence, were reviewed. Conclusively it reveals that ophthalmologists are concerned with communicating bad news effectively but lack related studies. Nevertheless, there is a growing realization that training in breaking bad news can increase physicians' confidence during communication, thus, benefiting the therapeutic relationship with the patient and his family. Therefore, it would be valuable to include breaking bad news training in the curriculum of residencies.

ABSTRACT Purpose: To assess the effect of the coronavirus disease 2019 (COVID-19) pandemic on cataract surgery by residents who had mandatory surgical simulator training during residency. Methods: In this retrospective, observational analytical study, the total number of cataract surgeries and surgical complications by all senior residents of 2019 (2019 class; prepandemic) and 2020 (2020 class; affected by the reduced number of elective surgeries due to the COVID-19 pandemic) were collected and compared. All residents had routine mandatory cataract surgery training on a virtual surgical simulator during residency. The total score obtained by these residents on cataract challenges of the surgical simulator was also evaluated. Results: The 2020 and 2019 classes performed 1275 and 2561 cataract surgeries, respectively. This revealed a reduction of 50.2% in the total number of procedures performed by the 2020 class because of the pandemic. The incidence of surgical complications was not statistically different between the two groups (4.2% in the 2019 class and 4.9% in the 2020 class; p=0.314). Both groups also did not differ in their mean scores on the simulator's cataract challenges (p<0.696). Conclusion: Despite the reduction of 50.2% in the total number of cataract surgeries performed by senior residents of 2020 during the COVID-19 pandemic, the incidence of surgical complications did not increase. This suggests that surgical simulator training during residency mitigated the negative effects of the reduced surgical volume during the pandemic.

Introducción: La oftalmología es la ciencia de la medicina que se encarga del estudio del sistema visual y el órgano de la visión, así como de sus anexos. Para ello es dotada de un conjunto de tecnologías de avanzada que permite describir las múltiples patologías que tienen los pacientes. En la actualidad se nutre del uso de los dispositivos móviles, fundamentalmente en la gestión del conocimiento, pero no se explotan sus otras dimensiones. Objetivo: Identificar los referentes que fundamentan el uso de la telefonía móvil en el proceso de enseñanza aprendizaje del residente de oftalmología. Métodos: Se realizó una investigación de desarrollo tecnológico en el campo de la educación médica superior. Se utilizaron como métodos teóricos el histórico-lógico, el analítico-sintético y el método sistémico estructural funcional. Resultados: La telefonía móvil constituye una nueva tendencia en la educación superior cubana y en la educación médica como alternativa para desarrollar los procesos de enseñanza aprendizaje, a través de su uso para la socialización, la comunicación entre los estudiantes, y la gestión de la información, como medio de enseñanza aprendizaje y herramienta de trabajo. Conclusiones: Existe una contradicción entre la formación que deben tener los residentes en oftalmología en cuanto al uso de las tecnologías, y la preparación que poseen para su utilización en función de su especialidad. A pesar de que existen varios estudios que demuestran la importancia del uso de la telefonía móvil en la formación de los residentes de oftalmología, como objeto de estudio y herramienta de trabajo, no se ha establecido la vía para incluirla como una de las tecnologías dentro de la residencia de oftalmología en Cuba(AU)
Introduction: Ophthalmology is the medical science dealing with the study of the visual system and the organ of vision, as well as its annexes. For this purpose, it is equipped with a set of advanced technologies that allow describing the multiple pathologies presented by patients. Nowadays, it is nourished by the use of mobile devices, mainly in knowledge management, but its other dimensions are not exploited. Objective: To identify the references that support the use of mobile telephony in the teaching-learning process of ophthalmology residents. Methods: A technological development research was carried out in the field of higher medical education. As theoretical methods, the historical-logical, the analytical-synthetic, and the systemic-structural-functional methods were used. Results: Mobile telephony is a new trend in Cuban higher education, as well as in medical education, as an alternative to develop teaching-learning processes, through its use for socialization, communication among students, and information management, as a teaching-learning means and a work tool. Conclusions: There is some contradiction between the training that ophthalmology residents should receive with respect to the use of technologies and the preparation that they have for their usage in accordance with their specialty. Although there are several studies that demonstrate the importance of using mobile telephony in the training of ophthalmology residents, as an object for studying and a work tool, there has not been a way to include it as one of the technologies within the ophthalmology residency in Cuba(AU)

Background: In 1978, the advent of magnetic resonance imaging (MRI) was a remarkable volte-face in the world of diagnostics. Employing the phenomenon of nuclear resonance enables us to exploit the properties of differential protons in living tissues. The ability of providing higher and variable contrast and the absence of ionizing radiations make it superior to computed tomography. Being the diagnostic tool of choice, it is an indispensable part of assessment of the location and characteristics of different ocular and orbital pathologies (vascular, inflammatory, and neoplastic). Purpose: The intrinsic and extrinsic properties of MRI provide multi-parametric imaging, making it of paramount importance in ophthalmological evaluation. Also, MRI-dynamic color mapping provides non-invasive and quantitative assessment of soft tissues in motion. An in-depth knowledge of the basic principle and technique of MRI aids in diagnosing as well optimal planning of surgical interventions. Synopsis: In this video, we shall be displaying the anatomical, clinical, and radiological aspects of MRI with an overlap to make it easier to understand the implications of this miraculous invention. Highlights: A good understanding of MRI analysis makes the ophthalmologists independent and helps in ruling out the differential diagnoses, exact extent and invasion, precise surgical planning and therefore, avoiding tragic outcomes. This video is an attempt to simplify and emphasize on the importance of MRI interpretation for an ophthalmologist.

Purpose: During the coronavirus disease 2019 (COVID?19) pandemic, private practice, inpatient consult services, and academic residency programs in ophthalmology saw a decrease in patient encounters. This study elucidates how community hospital ophthalmology consult (OC) services were affected during the pandemic. We aim to determine whether there was a change in resident OC volume in a community?based ophthalmology program consult service during the COVID?19 pandemic. Secondary objectives included analyzing the change in the types of diagnoses and the number of patients seen for diabetic retinopathy over the same time. Methods: A retrospective cross?sectional study was conducted reviewing the electronic health record (EHR) charts from OCs for the period 2017–2021. Records were categorized by referral source and the nature of OCs (trauma, acute, or chronic); OCs were further grouped by year and weak of referral. An intermonth analysis of weekly OC counts in each category was performed for the average number of consults in February–April 2017–2019 and for February–April 2020. A one?tailed t?test was performed. All t?tests assumed equal variances. Results: Weekly OCs in 2020 revealed no statistically significant differences in overall cases or in acute or chronic cases when the volume before the COVID?19 pandemic was compared to the volume after the onset of the pandemic. However, a statistically significant increase in the average weekly trauma cases was noted when 2020 (an average of 2.7 cases per week) was compared to the weekly average for the same weeks of years 2017– 2019 (0.4; P = 0.016). This statistically significant increase in trauma in 2020 disappeared when comparing weeks 11–17 in 2020 (2.2 cases per week) and the average of 2017–2019 (1.1).Conclusion: This report outlines no significant change in OCs before and after the onset of the pandemic compared to three previous years. There was, however, an increase in trauma consults during the pandemic and an increase in the number (though not the proportion) of diabetic retinopathy (DR+) patients seen by residents. This report uniquely describes no significant changes in the resident volume of patients seen during the COVID?19 global pandemic
