[Application of Color Doppler ultrasonography in the evaluation of the blood flow in the ocular vessels in patients with anterior ischemic optic neuropathy--the preliminary report].
Klin Oczna. 2006; 108(7-9):290-3.KO

Abstract

PURPOSE

Anterior ischemic optic neuropathy (AION) is one of the most common causes of acute loss vision in the middle-aged and elderly persons. It occurs due to hypoperfusion in the short posterior ciliary arteries supplying the optic nerve head. The aim of our study was evaluation of the usefulness of colour Doppler ultrasonography in diagnostics of AION.

MATERIAL AND METHODS

Color Doppler imaging of the ophthalmic artery, central retinal artery and posterior ciliary arteries were performed in 10 patients with clinically evident AION. The peak-systolic velocity (PSV), end-systolic velocity (EDV) and resistance index (RI) were measured.

RESULTS

No significant differences in the mean values of PSV, EDV and RI of ophthalmic arteries and posterior ciliary arteries between the affected and non-affected eyes were found. Reduction of mean flow velocities as well as significantly increased resistance index were observed in the central retinal artery in eyes with AION.

CONCLUSIONS

The Color Doppler findings in the ciliary arteries do not reflect the ischemic changes in patients with AION. It is probably due to anatomical limitation of this method in evaluation of the blood flow in posterior ciliary arteries supplying the optic nerve head. Abnormal blood flow parameters in the central retinal artery are secondary changes due to optic disc oedema.
