CT was defined as the vertical distance between the outer surface of the retinal pigment epithelium and the junction of the choroid and sclera.

(A)黄斑中心凹及距离黄斑中心凹1 mm、2 mm、3 mm 鼻侧、颞侧的RT及CT测量位点(绿色水平线);(B)黄斑中心凹及距离黄斑中心凹1 mm、2 mm、3 mm 上方、下方的RT及CT测量位点(绿色垂直线)。
(A) The central fovea of the macula and the RT and CT measurement sites 1 mm, 2 mm, and 3 mm away from the central fovea of the macula on the nasal and temporal sides (green horizontal line); (B) The central fovea of the macula and the RT and CT measurement sites 1 mm, 2 mm, and 3 mm above and below the central fovea of the macula (green vertical line).
The Bland-Altman diagram of two rounds of central concave CT measurement before (A) and after (B) 1% atropine gel was used. The solid line represents the average difference, while the dashed line represents the 95% consistency limit (1.96 × SD). The examiner did not find any trend of difference in both examinations.
