role of ultrasonograhy in the differentiation of different types of cataract snd in the assessment of nuclear hardness

ABSTRACT

The aim of this work was to evaluate the role of standardized A-scan as well as B-scan ultrasonography in the differentiation between different types of cataract as well as in the assessment of nuclear hardness. Fifty eyes with senile cataract were examined to determine its clinical type [nuclear, cortical or posterior subcapsular] and the grading of nuclear hardness. Then, the examined eyes were analyzed with standardized A-scan echographic as well as B-scan echographic examinations. Then, the echographic patterns were correlated with the clinical types. The study concluded that standardized A-scan might be helpful in the assessment of nuclear hardness, especially in white cataract. B-scan ultrasonography was less reliable in determining the type of cataract
