Correlation of blue-on-yellow visual fields with scanning confocal laser optic disc measurements.

摘要: Purpose Visual field defects and changes in the optic nerve head are signs of glaucoma. It has been shown that blue-on-yellow (B-Y) perimetry can reveal visual earlier shows them larger than does white-on-white (W-W) perimetry. The Heidelberg retina tomograph (HRT) produce three-dimensional images disc. aim this study was to find out how B-Y results correlate with disc parameters comparison W-W results. Methods One randomly chosen eye evaluated each 40 normal subjects 37 patients ocular hypertension different stages fields (program 30-2) were obtained a Humphrey perimeter. adjusted for patient's age lens transmission index measured fluorometer. mean deviation (MD) calculated as difference between expected sensitivity values, predicted by regression model fitted subjects. HRT software version 1.11 used acquire evaluate topographic measurements Results cup shape measure showed strongest correlation MD both fields. multiple coefficients from quadratic 0.65 Except peripapillary retinal fiber layer measurements, statistically significant correlations indexes other equal or better those Conclusions MDs well correlated HRT. In early glaucoma, most variables MD.
