Normal Aging Changes of The Scattering Intensity in The Human Lens

ABSTRACT

This report represents a quantitative analysis of the human lens changes in density correlated with aging using the Scheimpflug Camera(EAS-1000, Nidek) and image analysis technique. We measured the scattering light intensity(biometric; analysis) of the 13 points from the anterior capsule to the posterior capsule in 156 eyes. In generally, the scattering intensity of lens anterior part was greater than that of posterior part. The scattering light intensity of lens was increased with aging except in the posterior subcapsule and posterior capsule. This results will assist the classification and monitoring of human cataracts grade.
