摘要
目的比较三种不同手持式眼底相机拍摄的视神经照片的质量,并评估每种相机垂直杯盘比(VCDR)测量的再现性和一致性。方法从泰国北部一家综合眼科诊所和一家玻璃体内注射诊所招募成年患者进行横断面研究。每个参与者都使用3台手持相机进行了视神经摄影:Volk iNview、Volk Pictor Plus和Peek Retina。两名照片分级员对VCDR图像进行掩蔽分级,第三名照片分级人员对VCDR差异大于0.2的图像进行评估。结果共355眼采用三种不同的手持式眼底相机进行了成像。在130只(37%)用Peek Retina成像的眼睛中,视神经图像被判定为不可解码,而在iNview和Pictor Plus成像的眼睛分别为36只(10%)和55只(15%)。对于193只具有来自所有3台相机的可分级图像的眼睛,每个相机的VCDR测量的评分者间可靠性较差或中等,组内相关系数在0.41至0.52之间。在iNview图像上有6只眼睛、Pictor Plus图像上有9只眼睛和Peek图像上有3只眼睛的VCDR≥0.6,相机之间的一致性较差(例如,在iNview和Pictor Plus的图像上没有一只眼睛被评为VCDR≥0.6%)。结论3台手持式摄像机VCDR分级的评分者间信度较差。相机对哪只眼睛有大的VCDR并不一致。
Comparison of Three Handheld Fundus Cameras for Assessment of the Vertical Cup-To-Disk Ratio.
Purpose To compare the quality of optic nerve photographs from three different handheld fundus cameras and to assess the reproducibility and agreement of vertical cup-to-disk ratio (VCDR) measurements from each camera. Methods Adult patients from a comprehensive ophthalmology clinic and an intravitreous injection clinic in northern Thailand were recruited for this cross-sectional study. Each participant had optic nerve photography performed with each of 3 handheld cameras: the Volk iNview, Volk Pictor Plus, and Peek Retina. Images were graded for VCDR in a masked fashion by two photo-graders and images with > 0.2 discrepancy in VCDR were assessed by a third photo-grader. Results A total of 355 eyes underwent imaging with three different handheld fundus cameras. Optic nerve images were judged ungradable in 130 (37%) eyes imaged with Peek Retina, compared to 36 (10%) and 55 (15%) eyes imaged with the iNview and Pictor Plus, respectively. For 193 eyes with gradable images from all 3 cameras, inter-rater reliability for VCDR measurements was poor or moderate for each of the cameras, with intraclass correlation coefficients ranging from 0.41 to 0.52. A VCDR ≥ 0.6 was found in 6 eyes on iNview images, 9 eyes on Pictor Plus images, and 3 eyes on Peek images, with poor agreement between cameras (e.g., no eyes graded as VCDR ≥ 0.6 on images from both the iNview and Pictor Plus). Conclusions Inter-rater reliability of VCDR grades from 3 handheld cameras was poor. Cameras did not agree on which eyes had large VCDRs.
期刊介绍:
Ophthalmic Epidemiology is dedicated to the publication of original research into eye and vision health in the fields of epidemiology, public health and the prevention of blindness. Ophthalmic Epidemiology publishes editorials, original research reports, systematic reviews and meta-analysis articles, brief communications and letters to the editor on all subjects related to ophthalmic epidemiology. A broad range of topics is suitable, such as: evaluating the risk of ocular diseases, general and specific study designs, screening program implementation and evaluation, eye health care access, delivery and outcomes, therapeutic efficacy or effectiveness, disease prognosis and quality of life, cost-benefit analysis, biostatistical theory and risk factor analysis. We are looking to expand our engagement with reports of international interest, including those regarding problems affecting developing countries, although reports from all over the world potentially are suitable. Clinical case reports, small case series (not enough for a cohort analysis) articles and animal research reports are not appropriate for this journal.
