B超诊断早产儿视网膜病有效性分析

目的:评估B超进行眼底检查的实用性及对ROP诊断的有效率。方法:2007年6月1日～2008年3月8日对112例早产儿运用B超和间接眼底镜检查,以间接眼底检查诊断ROP的结果为"金标准",记录B超检查眼底结果并进行统计学分析。结果:应用B超诊断224只眼睛,检出ROP病变13只眼睛,11只被间接眼底镜证实患有ROP,其敏感度为25%,特异度为98.9%,阳性预测值为84.6%,阴性预测值84.4%。结论:B超不是目前ROP筛查的理想手段,可在一定条件下进行早产儿的ROPⅢ期的随访,但由于其操作简单、安全性好,故此技术应继续深入研究。

Efficiency analysis on B-ultrasound diagnosis for retinopathy of premature infants

Objective: To evaluate the efficiency of B-ultrasound diagnosis for fundus examination and its effective rate for reti-nopathy. Methods: From June 1, 2007 to March 8, 2008, B-ultrasound and fundus examination were carried out on 112 premature in-fants, fundus examination was golden standard, then the results were recorded and analysed. Results: 13 eyes were diagnosed as retinopathy by B-ultrasound among 224 eyes, 11 eyes were identified by indirect ophthalmoscope, the sensitivity was 25%, specificity was 98. 9%,positive and negative predictive values were 84. 6% and 84. 4%, respectively. Conclusion: B-ultrasound isnt an effective method in the screening of retinopathy, which can be used to follow up in some special conditions, but the technique should be enhanced continually be-cause of its simple and safe operation.
