PURPOSE: Using a new analysis program for scanning laser-Doppler flowmetry (SLDF) with a Heidelberg retina flowmeter (HRF), the authors studied the relationship between flow and visual field or disc morphology. SUBJECTS AND METHODS: In 42 eyes of 21 patients with normal tension glaucoma (NTG), the mean flow of the HRF blood flow parameters at the disc rim was measured and analyzed by a new analysis program for perfusion maps (the SLDF analysis tool), to minimize the influence of large vessels or/and artifacts caused by small eye movements. The authors investigated whether difference in mean flow between a pair of eyes had any relation to differences between a pair of eyes in visual field indices and those in disc morphological measurements of the HRF. RESULTS: The authors found statistically significant correlations between the mean-flow and optic disc parameters (disc area, cup area, height variation contour, cup volume, rim volume, mean RNFL thickness). They found no statistically significant correlations between the mean-flow and visual field parameters (mean deviation, corrected pattern standard deviation). CONCLUSIONS: The results suggested that eyes with less flow in the optic disc rim have more advanced glaucomatous morphological changes. LA: Japanese
