Long-term Periodic Analysis of Senile Cataract with Computerized Anterior Segment Analyser

ABSTRACT

To evaluate the progression of the cataract, we examined the retroillumination and the slit image of the lens by using EAS-1000 Scheimpflug photography in 50 individuals(91 eyes) with senile cataract from September 1990 to January 1996. We analyzed the cataract progression periodically by retroillumination for opacity area(%) change and Scheimpflug photography for density change of at each eyes at the same time. And we examined cataract type progression by aging and medication effect. In the retroillumination image, the monthly increment of opacity areas were 1.24%. In the Scheimpflug photography(slit image), the monthly incerement was 4.23 CCT. Both the opacity area(%) changes and the density changes at each cataract type were faster in the young age group than other age group. Both the opacity area changes and the density changes were slower in the anticataract medication group than non-medication group, but it was statistically insignificant.
