Objective To analyze the clinical features and prognosis of isolated trochlear nerve palsy in our hospital.Methods The clinical data of 23 patients with isolated trochlear nerve palsy diagnosed in our hospital from October 2019 to February 2023 were retrospective analyzed.Results In this group,there were 15 males and 8 females.There were 8 cases of microvascular etiology,5 cases of non-specific inflammation,4 cases of trauma,2 cases of ischemic stroke,1 case of cerebral microhemorrhage,1 case of intracranial mass,1 case of idiopathic and 1 case of congenital.Except one case lost to follow-up,the complete recovery rate within 6 months of onset of the other 22 cases was 82％.There was no statistical difference between microvascular causes and non-microvascular causes.Conclusion The etiology and distribution of solitary trochlear nerve palsy are diverse,and isolated trochlear nerve palsy may be a signal of stroke,and the overall prognosis is good after conservative treatment,and the decision on whether to correct it with surgery can be followed up for at least 6 months.
