Abstract
AIM: To determine the frequency and prognostic value of eye deviation detected on the admission computed tomography (CT) of acute ischaemic stroke patients. MATERIALS AND METHODS: The clinical and imaging data from the Albumin in Acute Stroke (ALIAS) Trials 1 and 2 were analysed. Two reviewers evaluated all admission CT images for the presence of eye deviation, and Alberta Stroke Program Early CT Score (ASPECTS). The admission National Institutes of Health Stroke Scale (NIHSS) scores and 3-month modified Rankin scale (mRs) scores were ascertained. Disability or death was defined as mRS score >2, at 3-month follow-up. RESULTS: Of 1,223 patients included in the present series, 352 (28.8%) had rightward and 331 (27.1%) had leftward eye deviation on admission CT. Patients with eye deviation on CT had higher admission NIHSS score and larger middle cerebral artery (MCA) territory infarct volume (based on ASPECTS). The presence of eye deviation on CT was associated with higher rates of haemorrhagic transformation at 24 hours (19.8% versus 13.5%, p=0.004), and higher rates of disability or death at 3-month follow-up (53.1% versus 35.7%, p<0.001). Mediation analysis showed that radiological eye deviation relation with higher rate of disability or death is predominantly due to its association with higher admission NIHSS scores, lower ASPECTS, and to a lesser extent patients' older age. CONCLUSIONS: The presence of eye deviation on CT examination of acute ischaemic stroke patients is associated with larger anterior circulation stroke volumes, higher risk of 24-hour haemorrhagic transformation, and 3-month disability or death.
