Reserch progress of neuro-ophthalmic manifestations of coronavirus disease 2019 / 中华眼底病杂志

ABSTRACT

Currently, coronavirus disease 2019 (COVID-19) is still widely prevalent around the world, leading to a major threat to the global public health. COVID-19 mainly involves the respiratory system, but extrapulmonary manifestations including that of the nervous system also exist in the setting of COVID-19. Misdiagnosis and delayed treatment of the disease may easily cause when ocular, especially neuro-ophthalmological symptoms are the first symptoms in early COVID-19, as the neuroophthalmological manifestations are rarely reported. First-line clinicians need to ask about not only respiratory symptoms such as fever, cough and sore throat, but also diplopia, impaired vision, eye motion pain, abnormal gait or other neurological deficits at the first reception, as these extrapulmonary manifestations are often signs of serious infection. The neuroophthalmological manifestations and possible underlying etiology of COVID-19 were summarized in this review, hoping to provide an early identification and effective treatment of COVID-19 for clinicians. More extensive studies are needed in the future to confirm the causal relationship between COVID-19 and neuroophthalmological disease to provide a sufficient basis for a comprehensive understanding of COVID-19.
