Retinal microvascular alterations reflect cerebral small vessel disease burden in frontotemporal dementia: a multimodal OCTA–MRI Study

Topic: Risk, prevention and care in population studies
FTD patients demonstrated significantly reduced retinal and choriocapillaris perfusion compared to CU (all p < 0.001). Notably, decreased superficial vascular complex (SVC) density correlated with higher WMH and PVS volumes. Choriocapillaris perfusion showed the highest diagnostic accuracy (AUC = 0.993) for distinguishing FTD from CU. Furthermore, OCTA metrics, particularly reduced SVC density, were significantly associated with increased SVD burden, indicating a link between retinal microvascular changes and cerebral small vessel pathology in FTD. Our findings support a retina–brain microvascular axis in FTD, where retinal microvascular alterations may reflect cerebral SVD burden. These results highlight the potential of OCTA as a noninvasive biomarker for monitoring vascular contributions to frontotemporal neurodegeneration. The study provides a framework that using OCTA-derived metrics may help improve early diagnosis, disease stratification, and monitoring of vascular involvement in FTD.
Key findings
- FTD patients demonstrated significantly reduced retinal and choriocapillaris perfusion compared to CU (all p < 0.001).
- Notably, decreased superficial vascular complex (SVC) density correlated with higher WMH and PVS volumes.
- Choriocapillaris perfusion showed the highest diagnostic accuracy (AUC = 0.993) for distinguishing FTD from CU.
- Furthermore, OCTA metrics, particularly reduced SVC density, were significantly associated with increased SVD burden, indicating a link between retinal microvascular changes and cerebral small vessel pathology in FTD.
- Our findings support a retina–brain microvascular axis in FTD, where retinal microvascular alterations may reflect cerebral SVD burden.
Why it matters
In this cross-sectional study, people with frontotemporal dementia had reduced retinal and choriocapillaris perfusion compared to controls, and these retinal changes correlated with cerebral small vessel disease burden. The findings suggest OCTA could be a noninvasive biomarker for monitoring vascular contributions, but no treatment or prevention is tested.
