ABSTRACT
Although coronavirus disease-2019 (COVID-19) is mainly a respiratory system disease, neurological complications due to peripheral and central nervous system involvement may be seen in these patients. In this case report, we described a patient with isolated abducens nerve palsy after COVID-19. The patient was a healthy 28-year-old man who developed isolated abducens nerve palsy 10 days after COVID-19. He had no systemic risk factors. He had 20 PD left esotropia (ET) at distance and 16 PD left ET at near in primary position and ET increasing to 25 PD in left gaze. He had left abduction deficiency. His cranio-orbital magnetic resonance imaging findings were normal. He was diagnosed as left isolated abducens nerve palsy and his findings were recovered after 2 months. COVID-19 may cause ocular motor nerve palsies. Although the pathological mechanism remains unclear, direct viral invasion, inflammatory and immune mechanisms may play role. Further case reports and studies are needed to support these findings.

Coronavirus disease 2019 (COVID-19) is a multisystem, inflammatory condition usually presenting with respiratory symptoms, such as fever, shortness of breath, and severe cough. It may also present with ocular, neurological, and musculoskeletal manifestations. However, since the emergence of the disease in 2019, only a few cases with ocular involvement have been reported in the literature. We present a case of acquired Brown syndrome secondary to COVID-19.
