A Study for Measurement of the Anterior Chamber Depth and Angle Using Image Analysis Technique in Cataractous Eyes

ABSTRACT

We measured the anterior chamber depth and chamber angle to understand the biological structure of anterior segment and find a possible relation between cataract and angle closure glaucoma on 235 eyes over 40 years old divided into two groups 111 cataract eyes and 124 normal control eyes using the Scheimpflug Camera(EAS-1000, Nidek, Japan) and image analysis technique. The values of the anterior chamber depth and angle of the eye of the young person were greater than those of older person, and the values in the male were deeper(p<0.01) and larger(p<0.05) than those in female in both groups. In cata ract eyes, the mean anterior chamber depth was 2.77mm and mean anterior chamber angle was 30.36 degrees. The mean anterior chamber depth and angle of normal control eye were 2.67mm and 29.10 degrees. The anterior chamber depth and angle in cataract group was deeper(p<0.05) and larger(p<0.05) than in normal control group.
