“…To date most of these angle studies, especially the larger ones, have been performed in adult Asian populations (Usui et al 2011;Shi et al 2012;Hong et al 2013), and only a few such studies have sought to assess the angle in children (Urbak 1999;Jin et al 2016;Fern andez-Vigo et al 2017;Tandon et al 2017). This lack of literature data also means that the possible effects of several factors such as gender, age, refractive error, angle or TM measurements on the size of the anterior chamber angle and its structures have yet to be addressed.…”

Purpose To measure the Schlemm's canal (SC) in vivo by Fourier‐domain optical coherence tomography (FD‐OCT) in a Caucasian paediatric population. Methods Participants of this cross‐sectional study were 290 healthy children. In the right eye of each child, SC cross‐sectional diameter and area measurements were made with the FD‐OCT instrument RTVue® (Optovue Inc, Fremont, CA, USA) in the nasal and temporal quadrants. These SC variables were then assessed for correlation with the factors age, gender, refractive error, anterior chamber angle and trabecular meshwork (TM) metrics. Finally, the reproducibility of the SC measurements was assessed in 30 of the participants. Results Mean participant age was 10.7 ± 3.4 years (range 3–18). SC diameters could be measured in both quadrants in 70.6% and 70.4% of subjects, respectively. Mean SC diameters were similar (p = 0.125) for the temporal and nasal quadrants: 266.7 ± 84.1 μm (range 131–509) and 273.2 ± 77.3 μm (range 124–486), respectively. Mean SC areas were also similar (p = 0.167) for the two quadrants: 9975 ± 3514 μm2 (range 4000–23 000) versus 9688 ± 3297 μm2 (range 3000–24 000). No differences were detected in SC measurements according to gender, refractive error or angle and TM measurements (R ≤ 0.116; p ≥ 0.125). The exception was age which was directly correlated with SC size (p ≤ 0.041). The reproducibility of the SC measurements was excellent (intraclass correlation coefficients ≥0.936). Conclusion FD‐OCT allows the identification of the SC in children. Our data indicate an increase in SC size produced with age.

“…Developmental glaucomas, such as primary congenital glaucoma (PCG) and juvenile-onset open angle glaucoma (JOAG), are known to have anomalies in the angle that manifest as goniodysgenesis and are the cause of glaucoma at an early age in life. Urbak, in 1999, analyzed the angle in JOAG eyes using ultrasound biomicroscopy (UBM) but could not find any changes of angle dysgenesis on UBM despite gonioscopic evidence of dysgenesis in these eyes. 9 We studied the anterior segment of children with PCG and found angle anomalies that could be discerned on UBM.…”
