目的:探讨分析超声乳化手术前作视觉电生理检查对白内障预后的临床价值。方法:选取2009-01/2010-10在我院行白内障超声乳化手术治疗的白内障患者,针对直接和间接眼底镜下眼底窥不清253例,术前作视觉电生理检查了解视网膜和视神经情况以判断预后。结果:该253例患者中有47例经视觉电生理检查提示预后较差,其中接受白内障手术37例,有35例术后视功能恢复也相应较差(术后视力提高≤2行),2例术后视功能恢复情况相对较好(术后视力提高>2行),另10例放弃手术;206例经视觉电生理检查提示预后较好,其中201例接受白内障手术,有199例术后视功能恢复也相应较好(术后视力提高>2行),2例术后视功能恢复情况相对较差(术后视力提高≤2行),5例因有全身其他疾病不能手术。结论:白内障术前作视觉电生理检查了解视网膜及视神经情况,对于判断手术预后有良好的可预测性。

AIM:To evaluate the examination of visual electroph-ysiology for the prognosis of cataract before phacoemulsification.METHODS:All of 253 cataract patients whose fundus was unclear by direct ophthalmoscope or binocular indirective ophthalmoscope underwent phacoemulsification in our hospital from Jan.2009 to Oct.2010.Retina and optic nerve were preoperatively examined by visual electrophysiology to estimate the prognosis of cataract.RESULTS:The examination of visual electrophysiology showed the prognosis was poor in 47 cases.Phacoemulsification was performed in 37 cases,including 35 cases with poor prognosis(the increase of visual acuity postoperatively≤2),2 cases with well prognosis(the increase of visual acuity postoperatively>2),10 cases gave up the surgery.206 cases had well prognosis through examination and 201 cases underwent phacoemulsification.199 cases had well prognosis(the increase of visual acuity postoperatively>2),poor prognosis in 2 cases(the increase of visual acuity postoperatively≤2),5 cases couldn’t undergo surgery for systemic diseases.CONCLUSION:The examination of visual electrophysiology on retina and optic nerve before phacoemulsification have good predictability in the prognosis of cataract.
