Hypothesis
The reduced mean-D in CADASIL patients mirrors the cerebral microvascular changes associated with the disease.
Conclusion
Fractal analysis is a sensitive tool to assess changes in retinal vessel branching, reflecting early brain microvessel alterations in CADASIL patients.
Supporting Evidence
- Fractal analysis revealed that mean-D value of CADASIL patients was lower than that of controls.
- No correlation was found between mean-D and disease duration or MRI lesion volumes in CADASIL patients.
- The study suggests that retinal fractal analysis could be a diagnostic tool for detecting vascular abnormalities.
Takeaway
The study looked at the blood vessels in the eyes of people with a brain disease called CADASIL and found that their blood vessels were less complex than those of healthy people.
Methodology
The study involved ophthalmoscopic examination and fractal analysis of retinal photographs from CADASIL patients and matched controls.
Limitations
The small number of subjects included in the study precludes any definitive interpretation.
Participant Demographics
10 patients with CADASIL and 10 age- and sex-matched healthy volunteers.
