511名男性中学生,年龄16～19岁,视力正常,屈光不正度数在-0.50D～+1.00D之间,无自觉症状。用国产隐斜计检查,结果显示各类隐斜的正常范围,外隐斜0～6△,内隐斜0～8△,上下隐斜0～1.5△。各类隐斜的度数与人数频率的分布特征是,正位眼很少,仅占3.7%,其余96.3%均有不同类型不同程度的隐斜,其中内隐斜多于外隐斜,右上隐斜多于左上隐斜(即右下隐斜),且垂直性隐斜者95%以上伴有水平隐斜,而水平性隐斜者60～7O%伴有垂直性隐斜。单纯水平性隐斜或单纯垂直性隐斜者人数较少;隐斜度也较小。本组中各类隐斜的变异系数较大,说明青少年中的各类隐斜是不稳定的。
511 male high school students, aged 16 to 19 years old, normal vision, degree of refractive error between -0.50D ~ + 1.00D, no symptoms. With domestic phoria meter examination, the results showed that the normal range of various types of phoria, external implicit oblique 0 ~ 6 △, hidden implicit 0 ~ 8 △, implicit up and down 0 ~ 1.5 △. The distribution characteristics of various types of phoria and number of frequencies are as follows: there are only few orthoptic eyes, accounting for only 3.7%, while the remaining 96.3% have different types of phoria, of which the implicit oblique is more than the phoria, the right is hidden Oblique more than the left upper phoria (ie, right lower phoria), and more than 95% of the vertical phoria with horizontal phoria, and horizontal phoria 60 ~ 70% with vertical phoria. The number of simple phoria or simple vertical phoria is less; the phoria is also smaller. The coefficient of variation of all kinds of phoria in this group is larger, which shows that all kinds of phoria in teenagers are unstable.
