Abstract:
Objective To analyze the clinical,radiological features and risk factors of diplopia in patients with acute lacunar infarction (ALI).Methods Retrospectively retrieved patients of ALI (lesion diameter was less than 1.5 cm in DWI sequence)diagnosed by MR and clinical.We further summarized 13 ALI patients with diplopia and randomly selected 13 ALI patients without diplopia as the control group. SPSS22.0 statistical software was used for statistical analysis.The general clinical data such as sex and age was compared by Ch-i square test and t-test.The risk factors were primarily analyzed by one-way ANOVA and then the risk factors with statistical significance were brought into the logistic regression model for multivariate analysis.Results The incidence of diplopia in ALI patients was about 2.7%(13/489). The infarct sites were all located in the brain stem of the oculomotor-related brain nucleus and the dorsolateral medulla oblongata.Hypertension and hematocrit were negatively correlated with diplopia after infarction (P＜0.05 ).Conclusion The incidence of diplopia is low in ALI patients.The medial longitudinal tract of the dorsolateral medulla is an important area causing diplopia.Hypertension and hematocrit are non-risk factors for diplopia after ALI.
