To determine the agreement between two ophthalmologists in the evaluation of two important funduscopic features related to acute retinal artery occlusion: retinal cloudy swelling and visible retinal emboli.
An interobserver variability study in which two ophthalmologists (one trained in glaucoma, the other in neuro-ophthalmology) independently viewed fundus photographs and categorized them with respect to the presence or absence of cloudy swelling and retinal emboli. Inter- and intraobserver agreement was calculated with the kappa statistic.
Retina service at a university-affiliated hospital in Kingston, Ont.
The fundus photographs of 102 patients were included: 60 with acute retinal artery occlusion, 30 with conditions mimicking acute retinal artery occlusion and 12 healthy patients.
Both interobserver and intraobserver agreement as to the presence of retinal cloudy swelling were very high (kappa = 0.835 and 0.866 respectively). More variability was seen for the presence of retinal emboli, but, overall, interobserver and intraobserver agreement were still high (kappa = 0.726 and 0.629 respectively).
Our results suggest that clinicians use similar visual clues to categorize fundi with respect to retinal cloudy swelling and visible retinal emboli.
确定两位眼科医生在评估与急性视网膜动脉阻塞相关的两个重要眼底特征（视网膜混浊肿胀和可见视网膜栓子）时的一致性。
一项观察者间变异性研究，其中两位眼科医生（一位接受青光眼培训，另一位接受神经眼科培训）独立查看眼底照片，并根据是否存在混浊肿胀和视网膜栓子对其进行分类。使用kappa统计量计算观察者间和观察者内的一致性。
安大略省金斯敦一家大学附属医院的视网膜科。
纳入了102例患者的眼底照片：60例急性视网膜动脉阻塞患者、30例疑似急性视网膜动脉阻塞患者和12例健康患者。
关于视网膜混浊肿胀的存在，观察者间和观察者内的一致性都非常高（kappa分别为0.835和0.866）。视网膜栓子的存在显示出更多变异性，但总体而言，观察者间和观察者内的一致性仍然很高（kappa分别为0.726和0.629）。
我们的结果表明，临床医生在根据视网膜混浊肿胀和可见视网膜栓子对眼底进行分类时使用了相似的视觉线索。
