What this trial studies

This longitudinal observational study focuses on patients admitted with acute ischemic stroke at the Regional Stroke Unit at Oslo University Hospital. It aims to determine the prevalence of visual impairment in these patients during the acute phase and after three months, comparing those treated with endovascular therapy (EVT) to those who are not. The study will utilize the Vision Screening Assessment (VISA) tool to evaluate visual impairment and assess its sensitivity and specificity. A total of 120 patients will be included based on specific eligibility criteria.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who have experienced an acute ischemic stroke with a National Institute of Health Stroke Scale (NIHSS) score of less than 20.

Not a fit: Patients with more severe neurological deficits or those unable to provide consent will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the understanding and management of visual impairment in stroke patients, leading to better rehabilitation strategies.

How similar studies have performed: While there is limited data on similar observational studies specifically focusing on visual impairment post-stroke, the approach of using the VISA tool has shown promise in other contexts.
