- Abstract
Purpose: To evaluate several anterior chamber parameters in healthy young adults using spectral-domain optical coherence tomography and to describe the repeatability and reproducibility of this method.Study design: Prospective clinical study.Methods: Fifty-two eyes of 52 healthy volunteers were enrolled. Manual measurements of the anterior chamber angle (ACA500 and ACA750), angle opening distance (AOD500 and AOD750), angle-to-angle distance (ATA), anterior chamber width (ACW), and lens vault (LV) were obtained.Results: The mean nasal ACA500 was 44.87 ± 12.92°; ACA750, 43.94 ± 10.41°; AOD500, 672.54 ± 270.19 µm; AOD750, 881.87 ± 290.55 µm. The mean temporal ACA500 was 41.46 ± 11.20°; ACA750, 41.27 ± 11.31°; AOD500, 603.15 ± 232.28 µm; AOD750, 823.46 ± 308.76 µm. The differences between the corresponding nasal and temporal parameters were statistically significant. The ACW was 11.97 ± 0.42 mm, the ATA was 12.10 ± 0.43 mm, and the LV was 3.71 ± 232.93 µm. The ACA was highly associated with the LV. The intraclass correlation coefficients ranged from 0.984 to 0.999 for the intraobserver repeatability and from 0.966 to 0.998 for the interobserver reproducibility.Conclusions: This study assessed anterior chamber parameters in healthy young adults using spectral-domain optical coherence tomography. This technique reveals the spatial relationships of the ocular structures, provides high-resolution images, and results in high degrees of intraobserver and interobserver repeatabilities.
