Introduction:
This study aimed to describe retinal microvascular changes in patients diagnosed to
have stroke and determine the association between retinal microvascular changes and type of
stroke (lacunar and non-lacunar).
Methods:
This is a cross-sectional descriptive study conducted among stroke patients seen at the
Neurology Ward and Neurology Out-Patient Clinic of the UERM Memorial Medical Center. The
patients' demographic characteristics and risk factors were obtained through a standardized
questionnaire. Retinal photographs of both eyes were taken in eligible patients who consented to join
the study. Retinal vascular changes were identified and their association with the type of stroke was
determined.
Results :
Thirty-seven patients, 64% of whom had small artery occlusion type of lacunar stroke, were
enrolled in the study. The most prevalent retinal abnormalities for each type of stroke were AV
nicking and focal arteriolar narrowing. The prevalence of abnormal retinal findings between
patients with lacunar stroke and non-lacunar stroke were compared and showed insufficient
evidence to demonstrate a statistical significance between abnormal retinal findings and lacunar
stroke.
Conclusion
There is no significant association between abnormal retinal findings and lacunar
stroke.

Vascular endothelial growth factor (VEGF) has been shown to play a central role in the pathophysiologic
process underlying neovascular eye diseases. As such, anti-VEGF-based pharmacologic agents have emerged as a
highly effective treatment modality for various visually debilitating retinal and choroidal vascular pathologies. The
introduction of these pharmacologic agents directly into the vitreous cavity by means of an injection through the
pars plana has become a widely performed ophthalmic procedure both locally and overseas.
