Abstract
BACKGROUND

A subtype of the Omicron variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is suggested to be responsible for the outbreak in Northern China since the quarantine was lifted in December 2022. The coronavirus disease 2019 virus is primarily responsible for the development of respiratory illnesses, however, it can present a plethora of symptoms affecting a myriad of body organs. This virus has been theorized to be linked to demyelinating lesions of the peripheral and central nervous system including transverse myelitis and acute retrobulbar optic neuritis (ARON). For example, magnetic resonance imaging (MRI) of the orbit and brain showed enlargement of the retrobulbar intraorbital segments of the optic nerve with high T2 signal, and no abnormalities were seen in the brain tissue. In this case series, we analyzed the connection between SARS-CoV-2 infection and the onset of ARON.

CASE SUMMARY

Fifteen patients, and a teenage boy who did not have any pre-existing ocular or demyelinating diseases suddenly experienced a loss of vision after SARS-CoV-2 infection. The patients expressed a central scotoma and a fever as the primary concern. The results of the fundus photography were found to be normal. However, the automated perimetry and MRI scans showed evidence of some typical signs. Out of the 15 patients diagnosed with ARON after SARS-CoV-2 infection, only one individual tested positive for the aquaporin-4 antibody.

CONCLUSION

Direct viral invasion of the central nervous system and an immune-related process are the two primary causes of SARS-CoV-2-related ARON.

Core Tip: Our study is the first to elucidate the relationship between the Omicron variant of severe acute respiratory syndrome coronavirus 2 and acute retrobulbar optic neuritis in China, which may be attributed to two main factors: Immune involvement in the process and direct viral infiltration of the central nervous system. In addition, hypoxia and ischemia may be associated with the appearance of this disease. Further investigation is needed to gain a more complete picture of this relationship.
