【摘要】:目的探討青少年屈光參差患者配戴角膜塑形鏡3年后眼軸、中央角膜厚度及角膜內(nèi)皮細(xì)胞密度的變化。設(shè)計(jì)回顧性病例系列。研究對(duì)象2011-2013年在北京同仁驗(yàn)光配鏡中心驗(yàn)配角膜塑形鏡且連續(xù)戴鏡3年以上、按時(shí)復(fù)診的近視性屈光參差青少年患者21例(42眼)。方法依近視度數(shù)將患眼分為高度數(shù)眼組(高于-3.00 D)及低度數(shù)眼組(低于等于-3.00 D),觀察并比較戴鏡前及戴鏡6個(gè)月、1年、2年、3年后各組眼軸、中央角膜厚度及角膜內(nèi)皮細(xì)胞密度等參數(shù)的變化。主要指標(biāo)眼軸、中央角膜厚度、角膜內(nèi)皮細(xì)胞密度。結(jié)果戴鏡前及戴鏡6個(gè)月、1年、2年、3年后高度數(shù)眼組眼軸分別為(25.16±0.78)mm、(25.27±0.81)mm、(25.43±0.91)mm、(25.50±0.85)mm和(25.64±0.87)mm,低度數(shù)眼組眼軸分別為(24.13±0.99)mm、(24.38±0.96)mm、(24.49±1.00)mm、(24.71±0.94)mm和(24.88±1.01)mm,雙眼眼軸均隨時(shí)間增長(zhǎng)(F=48.2;P=0.000),高度數(shù)眼組眼軸更長(zhǎng)(F=10.186;P=0.003)。各時(shí)間點(diǎn)眼軸差異量分別為(1.03±0.45)mm、(0.90±0.40)mm、(0.85±0.39)mm、(0.79±0.41)mm及(0.76±0.44)mm,戴鏡后雙眼眼軸差異量逐漸縮小(F=9.494;P=0.000)。戴鏡前及戴鏡6個(gè)月、1年、2年、3年后高度數(shù)眼組角膜內(nèi)皮細(xì)胞密度分別為(3362.57±278.73)個(gè)/mm~2、(3393.67±325.88)個(gè)/mm~2、(3333.76±288.72)個(gè)/mm~2、(3276.90±240.49)個(gè)/mm~2及(3259.71±357.41)個(gè)/mm~2,低度數(shù)眼組角膜內(nèi)皮細(xì)胞密度分別為(3365.62±352.75)個(gè)/mm~2、(3387.62±363.57)個(gè)/mm~2、(3314.05±270.12)個(gè)/mm~2、(3290.71±327.64)個(gè)/mm~2及(3307.05±357.12)個(gè)/mm~2,隨著戴鏡時(shí)間延長(zhǎng),雙眼角膜內(nèi)皮細(xì)胞密度呈下降趨勢(shì)(F=4.386;P=0.006),雙眼間比較無(wú)統(tǒng)計(jì)學(xué)差異(F=0.007,P=0.932)。戴鏡前及戴鏡6個(gè)月、1年、2年、3年后高度數(shù)眼組中央角膜厚度分別為(548.81±28.34)μm、(531.43±33.30)μm、(526.05±30.84)μm、(523.38±27.54)μm和(525.29±27.92)μm,低度數(shù)組眼中央角膜厚度分別為(549.76±28.72)μm、(536.90±26.51)μm、(534.24±27.67)μm、(534.19±25.84)μm及(531.76±27.16)μm,戴鏡后6個(gè)月中央角膜厚度下降,以后無(wú)變化(F=56.843;P=0.000)。結(jié)論青少年近視性屈光參差患者長(zhǎng)期配戴角膜塑形鏡后雙眼眼軸差距縮小。角膜塑形效果于戴鏡6個(gè)月內(nèi)穩(wěn)定。
