摘要
目的 探讨视网膜计在白内障术前视力预测中的意义和应用价值。方法 随机选择各类白内障患者４８ 例（４８ 只眼） ，术前采用ＬＡＭＢＤＡ １００ 视网膜计检测患眼的预测视力，并与术后３ ｍｏ 时的矫正视力作比较。结果 预测视力与术后视力之间呈良好的正直线相关（ ｒ ＝ ０ ．８０２ ， Ｐ＜ ０ ．００５） ，结果完全一致８ 只眼（１６７ ％ ） ，假阳性１０ 只眼（２０８ ％ ） ，假阴性３０ 例（６２５ ％ ） 。结论 ＬＡＭＢＤＡ１００ 视网膜计能较准确地反映术前视网膜黄斑区的结构和功能状态，是一种较为理想的视力预测检查方法，但应注意减少假阳性或假阴性结果的产生。
Objective To evaluate a retinometer examination, used as a method in the prediction of postoperative visual acuity(PPVA)in patients with cataract. Methods 48 patients(48 eyes) underwent extracapsular cataract extraction with posterior chamber lens implantation.The PPVA was examined on every patient by LAMBDA100 retinometer before operation and compared with the corrected postoperative visual acuity(PVA).Results There was a good positive correlation between PPVA and PVA(r=0.802,P<0.005). Compared with PPVA,8 cases(16.7%)got consistent results,10 cases (20.8)got poorer results and 30 cases (62.5%) got better results.Conclusion The examination by LAMBDA100 retinometer could show the condition of macula area accurately,it is a valuable method in the examination of PPVA before ECCE/IOL. It is also discussed how to reduce the poorer or better result.
