Biometry and spectral domain optical coherence tomography parameters in children with large cupping

The purpose of this study is to investigate optic nerve head using spectral domain optical coherence tomography (SD-OCT) in children with large cupping. 111 eyes (4–10 years) were divided into three groups according to the cup to disc ratio: group 1, ≤0.3; group 2, 0.4–0.6; and group 3, ≥0.7. The rim area, disc area, average cup to disc ratio, vertical cup to disc ratio, and cup volume were investigated using SD-OCT (Cirrus HD-OCT, Carl Zeiss,...
