方法：选取PIHS视网膜病变患者262例，观察PIHS分期、年龄、体质量、蛋白尿、平均动脉压、红细胞比容与PIHS视网膜病变的相关性。

结果：视网膜分期随着PIHS级别的增高而增高(χ²_回归=52.13， P<0.05)； 年龄与视网膜病变比较差异无统计学意义(χ²_回归=6.52，P>0.05)； 体质量越大，视网膜病变程度越高(χ²_回归=22.97， P<0.05)； 蛋白尿与视网膜病变线性相关(χ²_回归=40.16，P<0.05)； 视网膜病变程度随着平均动脉压的增高而增高(χ²_回归=44.38， P<0.05)； 视网膜病变程度随着红细胞比容增高而增高(χ²_回归=52.73， P<0.05)。

结论：PIHS分期、体质量、蛋白尿、平均动脉压、红细胞比容均是PIHS视网膜病变的相关危险因素。

METHODS:Two hundred and sixty-two cases with the PIHS retinal lesions were selected, and the correlation between PIHS stage, age, body mass, albuminuria, mean arterial blood pressure, hematocrit value and retinopathy in PIHS were observed.

RESULTS: Retinal stage increased with the increase of the grade of PIHS(χ²_regression=52.13, P<0.05); there was no statistical significance between age and retinopathy(χ²_regression=6.52, P>0.05); the greater body mass was, the higher the degree of retinopathy was(χ²_regression=22.97, P<0.05); albuminuria was associated with retinopathy(χ²_regression=40.16, P<0.05); the degree of retinopathy increased with the increase of mean arterial blood pressure(χ²_regression=44.38, P<0.05); the degree of retinopathy increased with the increase of hematocrit value(χ²_regression=52.73, P<0.05).

CONCLUSION: PIHS stage, body mass, albuminuria, mean arterial blood pressure, hematocrit value are the related risk factors of retinopathy in PIHS.
