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¡¾15.75(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¡¾0.39 mm in average. As the age increased, the ACD became shallower. The ACD for the nasal(1.87¡¾0.39 mm) and the superior(1.85¡¾0.39 mm) showed the significantly shallow depth than the ones for temporal(2.29¡¾0.40 mm) and inferior (2.20¡¾0.41 mm). In all 4 quadrants, the ACD gradually became shallower as the age increased 20s to 60s. The total ACA was 36.44¡¾6.76¡Æin average. As the age increased, the ACA became narrower. The ACA for superior(34.23¡¾7.52¡Æ) and inferior(33.27¡¾6.76¡Æ) showed the significantly narrow angle than the ones for the nasal(38.28¡¾7.28¡Æ) and temporal (39.98¡¾7.13¡Æ). 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.
