| 摘 要： | 目的 评价两种方法 联合预测白内障术后视力的可靠性及临床应用价值.方法 采用视网膜视力计和闪光视网膜电图(F-ERG)两种检查方法 对拟手术的各类型白内障109例(117眼)进行视功能评估,并将视网膜视力即潜视力(Potential visual acuity,PVA)和F-ERG b波振幅值与术后1月的最佳矫正视力(best corrected visual acuity,BCVA)进行分析比较.结果 晶体核轻中度混浊,术前PVA与术后BCVA呈显著的正线性相关性(r=0.587,P<0.01).晶体核严重混浊,术前PVA与术后BCVA无相关性(r=0.037,P>0.05).F-ERG b波振幅值为正常的50%~100%,术后BCVA≥0.5占68.47%,F-ERG b波振幅值低于正常的50%,术后BCVA全部<0.5.结论 视网膜计可以准确的量化预测轻中度晶体混浊的术后视力,但对晶体核或后囊严重混浊者预测偏差较大.而F-ERG的检查结果 不受晶体混浊程度的影响,可以定性判断视网膜的功能状态,因此将两者检查结果 结合起来可以更加准确地预测白内障术后视功能的改善情况.

| Abstract: | Objective To evaluate the joint of two methods predicting the reliability of visual acuity after cataract surgery and clinical application. Methods Retinometer and flash electroretinogram (F-ERG) were used to evaluate the visual function after cataract surgery in 109 cases(117eyes). The regressive analyses between the post-operative best corrected visual acuity(BCVA) and each of the following results. The potential visual acuity (PVA) and F-ERG were performed, respectively. Results The obvious linear-relati... |
