Summary
Retinal artery disease mirrors changes in small cerebral arteries, indicating shared pathology. This connection between retinal vascular abnormalities and cerebral small-vessel disease (SVD) holds true for both hypertensive and normotensive individuals.
Area of Science:
- Ophthalmology
- Neurology
- Vascular Medicine
Background:
- Cerebral small-vessel disease (SVD) is a significant cause of stroke and cognitive decline.
- Retinal vascular changes are increasingly recognized as potential indicators of systemic vascular health.
Purpose of the Study:
- To investigate the association between retinal artery disease and cerebral small-vessel disease (SVD).
Main Methods:
- Prospective cohort study involving 179 patients with symptomatic atherosclerotic disease.
- Retinal photographs and brain MRI were analyzed for vascular abnormalities.
- Standardized scoring lists were used for assessing retinal arterial narrowing, crossings, sclerosis, and tortuosity.
- White matter lesions (WML) and lacunar infarcts were assessed via MRI.
Main Results:
- 92% of patients with SVD showed at least one retinal vascular abnormality, compared to 77% without SVD (p < 0.01).
- Retinal arterial narrowing and sclerosis were significantly more frequent in patients with SVD.
- In normotensive patients, retinal vascular changes correlated with SVD signs (p = 0.01).
Conclusions:
- Pathological changes in retinal arteries parallel those in small cerebral arteries.
- This parallel suggests a common underlying vascular process affecting both the eye and brain.
- The findings are relevant for both hypertensive and normotensive patient populations.
