Child growth and development in the eye, the eye grew from a small, axial length gradually increase, if the eyeball as a sphere, it has three axes, namely, longitudinal, transverse, sagittal axis, a sphere is the length of the three-axis equivalent.

儿童的眼睛在生长发育中，眼球由小长大，眼轴逐渐增长，如果将眼球看成一个球体，它有三个轴，即纵轴、横轴、矢状轴，一个正球体的三个轴的长度相等。

Methods A prospective study of 48 patients with thoracolumbar junction burst fracture (T12-L2), 15 with and 33 without neurologic deficit were included. Computed tomographic scans were used to measure the sagittal and transverse diameters and the surface area of the spinal canal at the level of injury, as well as one level above and another level below the fracture level. Injury severity scores were calculated for both groups.

Result: Scoliosis was identified in 58 cases with Marfan syndrome (38 males and 20 females), the prevalence rate was 42.03%, male-female sex ratio was 1.18:1, 6 cases were in younger than 10-year-old group. 12 cases were in 11~20-year-old group, 19 cases were in 21~30-year-old group, 11 cases were in 31~40-year-old group, 7 cases were in 41~50-year-old group, 3 cases were in 51~60-year-old group. Mean magnitude of Cobb angle in coronal plane was 26.8°±27.8°, the types of scoliosis curve included thoracic curve (36 cases), thoracolumbar curve (11 cases), lumbar curve (2 cases), double curve (6 cases) and triple curve (3 cases), apex vertebraes were convex to the right side among single curves in 38 cases while 11 cases were convex to the left side. Mean magnitude of kyphosis in sagittal plane was 14.3°±13.2°, 5 patients had thoracic lordosis and 40 patients had hypokyphosis and 12 patients had normal kyphosis.
