To evaluate the image quality of a telemedicine screening program for retinal disease using a nonmydriatic camera among rural island communities in Bocas del Toro, Panama.
In June 2018, a group of three medical students volunteered at clinics operated by the Floating Doctors in the province of Bocas del Toro, Panama. Non-mydriatic images of the retina were obtained using the Pictor Plus (Volk Optical, Mentor OH), randomized, and sent to two board-certified ophthalmologists at the University of California, Irvine for analysis using a modified version of the FOTO-ED scale. Inter-rater reliability was calculated using the kappa statistic.
Seventy patients provided a total of 127 images. Average image quality was 3.31, and most frequent image quality was 4/5 on the FOTO-ED scale. Thirty patients had at least one eye image with ideal quality (42.86%), while only one patient had no adequate photos taken (1.43%). However, high quality images were obtained in both eyes in only 12 patients (17.14%). The inter-rater reliability between the two ophthalmologists was 0.614.
Further improvements are necessary to acquire higher quality images more reliably. This may include further training and experience or mydriasis.
评估在巴拿马博卡斯德尔托罗省的农村岛屿社区使用免散瞳相机进行视网膜疾病远程医疗筛查项目的图像质量。
2018年6月,一组三名医学生在巴拿马博卡斯德尔托罗省由流动医生运营的诊所志愿工作。使用Pictor Plus(沃尔克光学公司,俄亥俄州门托市)获取视网膜的免散瞳图像,进行随机分组,并发送给加利福尼亚大学欧文分校的两名获得委员会认证的眼科医生,使用改良版的FOTO - ED量表进行分析。使用kappa统计量计算评分者间信度。
70名患者共提供了127张图像。在FOTO - ED量表上,平均图像质量为3.31,最常见的图像质量为4/5。30名患者至少有一只眼睛的图像质量理想(42.86%),而只有一名患者没有拍摄到足够的照片(1.43%)。然而,只有12名患者(17.14%)双眼都获得了高质量图像。两名眼科医生之间的评分者间信度为0.614。
有必要进一步改进,以更可靠地获取更高质量的图像。这可能包括进一步的培训和经验积累或散瞳。
