A study was conducted to evaluate the relationship between ophthalmic artery (OA) color Doppler flow imaging (CDFI) and single photon emission computed tomography (SPECT) in ischemic cerebrovascular diseases.
We examined 32 patients (mean age; 64 years) having ischemic cerebrovascular diseases, who underwent OA CDFI and SPECT within ten days.
The OA CDFI findings showed a normal pattern in 3 patients, a sclerotic pattern in 9, a stenotic pattern in 11, and a reversed pattern in 9. SPECT showed severe hypoperfusion in 8 patients, moderate hypoperfusion in 8, mild hypoperfusion in 6, and normal perfusion in 10. Most of the cases with a normal and sclerotic pattern by OA CDFI showed normal or mild hypoperfusion on SPECT. Among the eleven patients showing the stenotic pattern, six (55%) showed normal or mild hypoperfusion on SPECT. The SPECT findings in the nine patients with the reversed pattern were severe or moderate hypoperfusion.
Among the ischemic cerebrovascular diseases, the cases showing a normal, sclerotic, and reversed pattern by OA CDFI correlated well with the SPECT findings. OA CDFI should be performed with SPECT for a more precise understanding of intracranial hemodynamics.
