N2 - BACKGROUND: Ocular haemodynamics play a prominent part in many ocular diseases. This leads to the need to determine ocular perfusion. Several studies reveal advantages of colour Doppler imaging (CDI) in ophthalmologic diagnostics. Little is known about correlation of CDI results with other methods. PATIENTS AND METHODS: N = 56 eyes were examined with CDI, laser Doppler flowmetry (LDF) and Langham-OBF (LOBF). Correlations between the methods were identified by the Spearman correlation coefficient (R). RESULTS: LDF correlated with time average maximum (TAMx) and mean (TAMn) velocity assessed by CDI in the long posterior ciliary artery (TAMx: R = 0.466, p = 0.038, n = 20; TAMn: R = 0.462; p = 0.040, n = 20), but not in the short posterior ciliary artery. LOBF correlated with pulsatility index (PI) and resistive index (RI) of CDI in short (PI: R = 0.514, p = 0.002, n = 35; RI: R = 0.438, p = 0.008, n = 35) and long posterior ciliary arteries (PI: R = 0.436, p = 0.009, n = 35; RI: R = 0.506, p = 0.002, n = 35). DISCUSSION: Methods strengthen each other by partial correlation. CDI allows a more detailed insight into ocular perfusion than the other methods.
