Table 1.
Corneal thickness in the central (2-mm diameter), para-central (2 to 5-mm diameter), and peripheral (5 to 6-mm diameter) cornea in both eyes of 614 normal Chinese children.
Fig 4.
Scatter plot indicating the position of minimum corneal thickness in the area 5 mm from the pupil center in the right eye of 614 normal Chinese children.
Along the vertical axis, a negative number represents the distance inferior to the pupil center, while a positive number represents the distance superior to the pupil center (μm). Along the horizontal axis, a negative number represents the distance temporal to the pupil center, while a positive number represents the distance nasal to the pupil center (μm).
Fig 5.
Scatter plot of the position of minimum corneal thickness in the left eyes of 614 normal Chinese children.
Along the verticat axis, a negative number represents the distance inferior to the pupil center, while a positive number represents the distance superior to the pupil center (μm). Along the horizontal axis, a negative number represents the distance temporal to the pupil center, while a positive number represents the distance nasal to the pupil center (μm).
