目的：探讨眼科广域数字成像系统(Retcam3)筛查早产儿视网膜病变(ROP)的能力及与眼压变化的关系。

方法：选取2017-08/2019-08我院收治的80例符合筛查标准的早产儿为研究对象，分别采用双目间接检眼镜和Retcam3系统检查，以前者检查结果为金标准，统计Retcam3系统筛查的灵敏度、特异度、阳性和阴性预测值，同时比较筛查前后患儿眼压变化情况。

结果：双目间接检眼镜检查ROP患儿37例69眼，Retcam3系统筛查ROP患儿35例65眼，Retcam3检查灵敏度为100%，特异度为95.8%，阳性预测值为94.2%，阴性预测值为100%。Retcam3筛查后左眼和右眼眼压均高于散瞳前(P<0.05)。

结论：Retcam3系统能较为准确地筛查ROP患者，但筛查后可引起眼压升高。

METHODS: A total of 80 premature infants who met the screening criteria admitted to our hospital from August 2017 to August 2019 were selected as subjects. They were screened by binocular indirect ophthalmoscope and Retcam3 system respectively. The former method was chosen as the gold standard, the sensitivity, specificity, positive and negative predictive values of Retcam3 system screening was calculated, the intraocular pressure changes before and after screening was compared.

RESULTS:A total of 37 children with ROP were examined by binocular indirect ophthalmoscopy. 35 infants with ROP were screened by Retcam3 system. The sensitivity of Retcam3 was 100%, the specificity was 95.8%, and the positive predictive value was 94.2%, the negative predictive value is 100%. The intraocular pressure of left eye and right eye after Retcam3 screening was higher than that before dilation, and the difference was statistically significant(P<0.05).

CONCLUSION: The Retcam3 system can accurately screen patients with ROP, while it can cause an increase in intraocular pressure after screening.
