【摘要】：目的探討不同對(duì)比度下視力在早期白內(nèi)障患者中的應(yīng)用價(jià)值。方法選取2014年6月-2015年3月貴州省婦幼保健院收治的白內(nèi)障患者49例(84眼)及同期在本院接受檢查的健康者42例(84眼),分別納入白內(nèi)障組和對(duì)照組。比較白內(nèi)障組與對(duì)照組不同對(duì)比度下視力log MAR值,篩選出最佳矯正視力≥0.8的受試者,并再次測(cè)定不同對(duì)比度下視力log MAR值,比較最佳矯正視力≥0.8的白內(nèi)障組患者和對(duì)照組受試者不同對(duì)比度下視力log MAR值。結(jié)果白內(nèi)障組與對(duì)照組最佳矯正遠(yuǎn)視力(t=1.542,P=0.137),最佳矯正近視力(t=0.953,P=0.267),差異無(wú)統(tǒng)計(jì)學(xué)意義(P0.05)。100%(t=2.157,P=0.035)、25%(t=1.994,P=0.047)、10%(t=2.584,P=0.010)對(duì)比度下,白內(nèi)障組患者的視力log MAR值均明顯高于對(duì)照組(P0.05)。對(duì)比度越低,白內(nèi)障組患者和對(duì)照組受試者的視力log MAR值越高(P0.05)。100%(t=2.078,P=0.041)、25%(t=2.285,P=0.023)、10%(t=2.396,P=0.017)對(duì)比度下,最佳矯正視力≥0.8的白內(nèi)障組患者的視力log MAR值均明顯高于對(duì)照組(P0.05)。對(duì)比度越低,白內(nèi)障組患者和對(duì)照組受試者的視力log MAR值越高(P0.05)。結(jié)論不同對(duì)比度下視力能夠準(zhǔn)確評(píng)估早期白內(nèi)障患者視覺功能,其靈敏度明顯高于最佳矯正視力。
[Abstract]:Objective to explore the application value of visual acuity in early cataract patients with different contrast. Methods 49 cases (84 eyes) of cataract treated in Guizhou Maternal and Child Health Hospital from June 2014 to March 2015 were selected and examined in our hospital at the same time. Methods 42 healthy subjects (84 eyes) were included in cataract group and control group. The visual acuity (log MAR) of cataract group and control group were compared with that of control group. The subjects with best corrected visual acuity (BCVA) 鈮，
