目的:研究闪光视网膜电图对黑核白内障术后效果的预测意义。方法:对21例28眼黑核白内障施行现代囊外及人工晶体植入术,术前常规行闪光视网膜电图检测,检测结果为:ERG各波形未引出或最大反应引出低平波。结果:白内障术后随访三个月至两年,矫正视力低于0.1者2眼,0.1至0.5者17眼,0.6至1.0者9眼。结论:闪光视网膜电图虽可做为视网膜功能评价的客观指标,可预测白内障术后效果,但该项检查受多种因素的影响,在黑核白内障病人闪光视网膜电图波形可能极差,然而白内障术后却获得了良好的视力,所以该检查不能作为对视网膜功能的唯一评价指标,要结合临床及其它检查结果综合分析,增强黑核白内障病人接受手术的信心。
OBJECTIVE: To study the predictive value of flash electro-optic electroretinography in the detection of postoperative effects of cataract in black nucleus. Methods: 21 cases (28 eyes) with cataract treated by extracapsular and intraocular lens implantation were performed with flash electroretinogram. The results showed that the ERG waveforms were not induced or the maximal response induced low-level wave. Results: All patients were followed up for three months to two years after cataract surgery. The corrected visual acuity was lower than 0.1 in 2 eyes, 0.1 to 0.5 eyes in 17 eyes and 0.6 to 1.0 eyes in 9 eyes. CONCLUSIONS: Although flash electroretinography can be used as an objective indicator of retinal function to predict the postoperative outcome of cataract, this test is influenced by many factors and the waveform of flash electroretinography may be very poor in patients with cataract After cataract surgery has received good vision, so the test can not be used as the only evaluation of retinal function, combined with clinical and other test results comprehensive analysis to enhance the confidence of patients with nuclear cataract surgery.
