Since the end of 2019, novel coronavirus disease (COVID-19) outbreak in Wuhan,China and rapidly spread. The pathogen of COVID-19 is novel coronavirus (2019-nCoV), which is virified to be highly homologous with severe acute respiratory?syndrome coronavirus (SARS-CoV) in 2003, and whether the eye surface infectious is associated with the respiratory disease has attracted the attention of researchers. Up to now, the virulence, transmmision way, and infectivity of 2019-nCoV have been understood, but the invasion mode and pathogenesis is under elucidated. The management of infactious source, cutting out of transmmision route and treatment of patients are the primary goal for prevention and control of COVID-19 *** is very important for ophthalmologists to effectively treat the eye diseases and at the same time to pay close attention for medical environment disinfection and personal pretection during the pandemic. In view of the urgent need of ophthalmologists for the proventional precedure, we publish the ‘Ophthalmic Management and Protective Procedure Under the COVID-19 Epidemic’ by li xiaoxin et al from Xiamen Eye Center and ‘ Strengthening Prevention and Control Measures of Medical Staffs in Ophthalmic Hospital Under the COVID-19 Epidemic’by Zhang Mingzhi et al from Joint Shantou International Eye Center of Shantou University and the Chinese University of Hong Kong as the references for ophthalmologists.
