Anterior Segment Parameters Using Scheimpflug Camera in Korean Adults

Abstract

Purpose : To evaluate the anterior segment parameters (anterior chamber depth: ACD and anterior chamber angle: ACA) according to sex and age in Korean adults. Methods : The average age of the 92 subjects(160 eyes) was 35.38±15.75(20∼68) years old. The anterior segment parameters was measured by a rotating Scheimpflug camera(Pentacam, Oculus, Wetzlar, German). The ACD and ACA at 4 quadrants(superior, inferior, nasal and temporal) were measured and their averages were evaluated. Results : The total ACD was 2.97±0.39 mm in average. As the age increased, the ACD became shallower. The ACD for the nasal(1.87±0.39 mm) and the superior(1.85±0.39 mm) showed the significantly shallow depth than the ones for temporal(2.29±0.40 mm) and inferior (2.20±0.41 mm). In all 4 quadrants, the ACD gradually became shallower as the age increased 20s to 60s. The total ACA was 36.44±6.76°in average. As the age increased, the ACA became narrower. The ACA for superior(34.23±7.52°) and inferior(33.27±6.76°) showed the significantly narrow angle than the ones for the nasal(38.28±7.28°) and temporal (39.98±7.13°). In all 4 quadrants, the ACA gradually became narrower as the age increased 20s to 60s. Conclusion : As the age increases, the ACD and ACA become shallow and narrow but the decreases for 4 quadrants appeared different in tendency.
