数字化视网膜照相术在早产儿视网膜病筛查中的应用

Digital retinal camera for screening of retinopathy of prematurity

摘要:

目的：评估数字化视网膜照相术（RetCam）进行眼底检查的实用性及对ROP诊断的有效率。方法：对2007年6月至2008年3月间我科收治的112例早产儿运用间接眼底镜和RetCam同时进行眼底检查，以间接眼底检查诊断ROP的结果为“金标准”，记录RetCam检查眼底结果并进行统计学分析。结果：应用RetCam共检出各期ROP 46眼，其中间接眼底镜检查证实有ROP 43眼，RetCam诊断ROP的敏感度为97.7%，特异度为98.3%，阳性预测值为93.5%，阴性预测值为99.4%，1例ROPⅠ期漏诊，RetCam与间接眼底镜对ROP诊断的一致率为97.3%。结论：RetCam是一种有效的ROP的诊断新方法，可推广应用。［中国当代儿科杂志，2010，12（10）：774-776］

Abstract:

OBJECTIVE: To evaluate the practicability and efficacy of digital retinal camera (RetCam) as a method for early diagnosis of retinopathy of prematurity (ROP). METHODS: One hundred and twelve preterm infants admitted to the First Hospital of Jilin University from June 2007 to March 2008 were enrolled. Fundus examinations were performed by indirect ophthalmoscope and RetCam respectively. The results from RetCam were compared with those from indirect ophthalmoscopy which was a “gold standard” for ROP screening. RESULTS: ROP was identified in 46 eyes by RetCam, and in 43 eyes by indirect ophthalmoscope. The sensitivity of RetCamII was 97.7% (43/44) and the specificity was 98.3% (177/180), and the positive and negative predictive values were 93.5% and 99.4%, respectively. The concordance rate for identification of ROP between RetCam and indirect ophthalmoscopy was 97.3%. CONCLUSIONS: RetCam is an effective method for the identification of ROP and is worth recommending.［Chin J Contemp Pediatr, 2010, 12 (10):774-776］
