To assess the reliability and accuracy of smartphones in diagnosing transmitted fundus images in comparison with a laptop.
Fundus images captured with a Topcon NW 200 camera were transferred onto a conventional laptop and a smartphone and given to ophthalmologists for diagnosis. The smartphone and the laptop diagnosis were compared with the actual face to face diagnosis statistically to assess their diagnostic accuracy.
Fundus images of 228 eyes of 114 patients (mean age 47 years,73.6% males) were included in the study. 92.5% eyes were correctly diagnosed by both smartphones and laptop. Smartphone analysis revealed 98% sensitivity,57% specificity and kappa value of 0.62 in comparison to laptop, suggessting substantial interrater agreement.
Smartphones are as effective as the laptop in diagnosing fundus pathologies and hold promise for teleophthalmology in future.
与笔记本电脑相比，评估智能手机诊断眼底图像传输的可靠性和准确性。
用拓普康NW 200相机拍摄的眼底图像被传输到一台传统笔记本电脑和一部智能手机上，并交给眼科医生进行诊断。将智能手机和笔记本电脑的诊断结果与实际面对面诊断进行统计学比较，以评估其诊断准确性。
114例患者（平均年龄47岁，男性占73.6%）的228只眼睛的眼底图像被纳入研究。智能手机和笔记本电脑对92.5%的眼睛诊断正确。与笔记本电脑相比，智能手机分析显示敏感性为98%，特异性为57%，kappa值为0.62，表明观察者间有实质性一致性。
智能手机在诊断眼底病变方面与笔记本电脑一样有效，并且在未来的远程眼科中有应用前景。
