摘要：

Two quantitative techniques, Scheimpflug photography and the lens density index (LDI), were used to measure lens density in 52 patients. In the Scheimpflug technique, a digitized slitlamp camera provides peak and average nuclear density based on a densitometric analysis of the lens nucleus. The LDI is a psychophysical measurement of the difference between retinal scotopic thresholds for two wave-lengths of light. Both the Scheimpflug technique and LDI revealed an age-related increase in lens density. Peak and average nuclear density were highly correlated with the LDI.
