Longitudinal diabetic retinopathy screening data

This data set contains repeated 4-field color fundus photos (1120 in total) of 70 patients in the diabetic retinopathy screening program of the Rotterdam Eye Hospital (Rotterdam, The Netherlands); the result of intra- and inter-visit registration by two methods (i2kRetina and WeVaR); and the grading and ranking of these results by two graders. ### Inclusion criteria: All patients with diabetes who were screened for diabetic retinopathy during one week in June 2013. ### Exclusion criteria: First-time patients and Patients who were not examined in the year before. Fundus image of both eyes of each patient were acquired using a non-mydriatic digital fundus camera (Topcon TRC-NW65) with a 45 degrees field of view after pupil dilation. Images of each visit were registered by two methods: WeVaR (see Adal et al, A Hierarchical Coarse-to-Fine Approach for Image Registration) and i2k Retina (DualAlign LLC; see here). Image mosaic movies were created from the registered, normalized fundus images

本数据集包含荷兰鹿特丹眼科医院（鹿特丹，荷兰）糖尿病视网膜病变筛查项目中的70位患者的重复4字段眼底彩色照片（共计1120张）；通过两种方法（i2kRetina和WeVaR）进行访视内和访视间的注册；以及由两位评分员对这些结果进行评分和排名。### 纳入标准：所有在2013年6月一周内接受糖尿病视网膜病变筛查的糖尿病患者。### 排除标准：初次就诊患者和在过去一年内未接受检查的患者。每位患者的双眼眼底图像均使用非散瞳式数字眼底相机（Topcon TRC-NW65）以45度视野进行拍摄。每个访视的图像通过两种方法进行注册：WeVaR（参见Adal等人《一种自顶向下的粗到细的图像配准方法》）和i2k Retina（DualAlign LLC；参见此处）。从已注册和归一化的眼底图像中创建了图像拼贴电影。
