AIM: To study the anterior chamber angle data in 52 normal Chinese people with slit-lamp-adapted optical coherence tomography (SL-OCT) and to investigate the difference and the characteristics. METHODS: A total of 102 eyes of 52 normal people were tested by Heidelberg SL-OCT. Quantity of anterior chamber angle was measured in various aspects. Statistic analysis was performed with SPSS software. RESULTS: The relationship among the biologic measure quantities was rectilineal, and the variability of the anterior chamber angle 750 μm° was the smallest. At the superior nasal, nasal, inferior nasal, inferior, inferior temporal, temporal, superior temporal and superior aspect, the anterior chamber angle 750 μm° was 32.26 ± 9.10, 34.97 ± 9.60, 36.41 ± 9.15, 35.30± 9.82, 37.78 ± 10.56, 36.81 ± 9.64, 35.40 ± 9.81 and 35.01 ± 9.73, with the minimal and the maximal values at the superior nasal and inferior temporal aspect, respectively. In the 0-9, 10-19, 20-29, 30-39, 40-49, 50-59, 60-69 and 70-79 years old age groups, the anterior chamber angle 750 μm° was 50.20 ± 6.98, 44.02 ± 5.84, 43.93 ± 5.94, 35.83 ± 6.62, 28.94 ± 6.66, 28.05 ± 7.37, 43.63 ± 9.19 and 29.68 ± 4.54, respectively, with the minimal and the maximal values in the 50-59 and the 0-9 years old age groups. CONCLUSION: According to SL-OCT, the narrowest and the widest aspects of anterior chamber angle are the superior nasal and the inferior temporal aspects. The anterior chamber angle grows wide with the age from 0 to 60 years old, and might grow wide again or keep unchanged after 60 years old. LA: Chinese
