ABSTRACT
Background: Evaluation of changes in visual field defects in post-stroke patients is very important given the large incidence rate. The aim of this study was to investigate the comparison of visual field defect post ischemic stroke patients.
Methods: The cross sectional is used in this study. In this study, field defects were assessed in patients who had passed the acute phase and the following 3 months. Furthermore, the change in the value of The Visual Field Index (VFI) and Mean Deviation (MD) that occurs in post-ischemic stroke patients is assessed. The number of samples was 18 subjects. Sampling technique with consecutive sampling. Hypothesis test used chi-square test. A two-tailed P-value of <0.05 was considered statistically significant.
Results: The results showed that both the right and left eye experienced improvement in MD after 3 months. In the right eye, the greatest changes were seen in mild degrees (first examination 11.1% to 22.2% at second examination) where moderate severity decreased in number. Whereas in the left eye the greatest change was in mild degrees from 38.9% to 27.75% and normal degrees increased from 22.2% to 38.9%. Comparison of VFI values in the field of view of post-acute ischemic stroke patients, it is known that the right eye (3.5%) has a greater mean increase in VFI values than the left eye (0.89%). There has been an increase in the visual field as assessed by the mean deviation and visual field index in ischemic stroke patients after the acute phase and after the next 3 months (p<0.05).
Conclusion: This analysis confirmed there has been an increase in the visual field as assessed by the mean deviation and visual field index in ischemic stroke patients after the acute phase and after the next 3 months.
