Methods The optical calculation was taken as the following by using the parameter of Gullstrand model eye:①The refraction of silicone filled eye in non-accommodative status;②The refraction of silicone filled eye in non-accommodative status;③The aniseikonia analysis when one eye filled with the silicone oil;④The IOL power re-calculation.

采用Gullstrand模型眼参数进行以下分析：①非调节状态下正常眼球与硅油填充后眼球的屈光状态；②调节状态下正常眼球与硅油填充后眼球的屈光状态；③无晶状体眼玻璃体腔填充后的屈光状态；④正常眼球与填充硅油后视网膜像放大率变化；⑤硅油填充后的白内障人工晶状体植入术人工晶状体度数的变化。

Oogonium develops into early oocyte in the ovary, and then the oocyte leaves the ovary for the coelomic fluid in the form of single cell or cell mass followed by the rapid separation of the group of oocytes into individual ones. Oocyte enters into the nephridium after its maturation. The rupture of germinal vesicle marks the oocyte maturation. Oocyte in the coelom does not have follicle membrane and vitelline membrane is formed and developed by the oocyte itself. Smaller oocyte (0μm in diameter) is round, and larger ones (≥60μm in diameter) is ovate. The short and long diameters of a morphologically mature oocyte are about 115—120μm and 140—145μm respectively, and the vitelline membrane is 7—9μm thick.

卵原细胞在卵巢中发育至早期卵母细胞时期单个或成团脱离卵巢入体腔液中，卵母细胞团细胞很快分离为单个细胞；卵母细胞在体腔液中发育成熟后进入肾管；生发泡破裂是卵母细胞成熟的标志；体腔中卵母细胞无滤泡膜，卵黄膜的形成与发育靠卵母细胞本身；卵径小于60μm的卵母细胞呈圆形，卵径大于60μm 的卵母细胞为卵圆形，形态上成熟的卵母细胞短径约115—120μm、长径约140—145μm、卵黄膜厚7—9μm。

The intravitreous injection of rhIGF-2 has no effect on the degree of myopia and axial length of the non-FD guinea pig, while it can induce significant increases in the degree of myopia and axial length in the FDM guinea pig and the effects are concentration dependent.

rhIGF-2玻璃体腔注射对豚鼠非遮盖眼的屈光度和眼轴长度无影响，但可使形觉剥夺眼近视屈光度增加，眼轴延长，其效应呈浓度依赖性。rhIGF-2可下调豚鼠眼视网膜－脉络膜内源性IGF-2的表达，效应呈浓度依赖性。
