Clinical Assessment of Scleral Canal Area in Glaucoma Using Spectral Domain Optical Coherence Tomography

Purpose To investigate anterior scleral canal (ASC) area in the eyes with glaucoma using spectral-domain optical coherence tomography (SD-OCT). Design Cross-sectional study. Methods This study included 206 eyes of 103 patients with glaucoma classified as 66 eyes of 33 patients with unilateral glaucoma and 140 eyes of 70 patients with bilateral glaucoma. Radial scan enhanced depth imaging SD-OCT centered on the optic disc was performed, and parameters that present ASC area such as ASC opening and the largest ASC area were obtained in each eye. The largest ASC area was the largest cross-sectional area of the ASC region identified between ...
