背景视网膜出血是一个重要的发现，在儿童虐待和意外头部外伤。没有标准化和有效的协议来以一致的方式描述它们。这项基于网络的研究的目的是建立一个新的视网膜出血描述工具的可靠性和有效性。材料和方法我们的工具是一个全面的问卷调查，这是应用视网膜示意图，将视网膜分为四个独立的区域。四个独立的观察者从80张视网膜照片中对视网膜出血进行评分。使用Fleiss κ统计量计算评估者间和评估者内一致性（每位检查者重复评估10张照片）。结果评价者间对乳头周围区出血的一致性较高，而对所有其他区的一致性仅为一般。仅后极的评估者内一致性较高。照片可能是一种不可靠的记录视网膜出血的方法，特别是从周边视网膜，因此强调了彻底的临床检查的重要性。结论本研究表明，该工具实现了一定的有效性描述出血的后视网膜。它在外围区域的表现不太好。
Background Retinal haemorrhages are an important finding in children with abusive and accidental head trauma. There are no standardised and validated protocols to describe them in a consistent manner. The aim of this web-based study was to establish the reliability and validity of a new retinal haemorrhage description tool. Materials and method Our tool is a comprehensive questionnaire, which is applied using a retinal schematic that divides the retina into four independent zones. Four independent observers scored retinal haemorrhages from 80 retinal photographs. Inter- and intra-rater agreement (by repeat assessment of 10 photographs for each examiner) were calculated using Fleiss κ statistics. Results A high inter-rater agreement was noted for haemorrhages in the peripapillary zones, whereas agreement was only fair for all other zones. Intra-rater agreement was high only for the posterior pole. Photographs may be an unreliable way of documenting retinal haemorrhages particularly from the peripheral retina, thus underscoring the importance of a thorough clinical examination. Conclusion This study shows that the tool achieves some validity for describing haemorrhages in the posterior retina. It performs less well in the peripheral zones.
