To evaluate a reference set based grading system for retinal nerve fiber layer photographs.
A total of 1,941 retinal nerve fiber layer photographs (Canon non-mydriatic camera) were evaluated using a reference grading system. The reference system consists of 25 photographs of the retinal nerve fiber layer (Canon CF60U camera) of normals and patients with glaucoma. Each reference photograph represents a score for the visibility of the nerve fibers. Superior and inferior regions of the 1,941 photographs of the sample of the normal population were matched separately to the references.
The standard deviation of between eyes differences was 2.76. This standard deviation compared reasonably to the standard deviation of 1.0 to 1.9 for real repeated measurements in an earlier study and indicates that the grading system has good accuracy in relation to the total range of 1 to 25. A clear relationship between photograph score and age was established.
The photographic grading system demonstrated that it is viable in a different setting. Therefore, evaluation of retinal nerve fiber layer photographs with a photographic reference set might help ophthalmologists and technicians to integrate retinal nerve fiber layer photography in their clinical practice.
评估基于参考集的视网膜神经纤维层照片分级系统。
使用参考分级系统对总共1941张视网膜神经纤维层照片（佳能免散瞳相机拍摄）进行评估。该参考系统由正常人和青光眼患者的25张视网膜神经纤维层照片（佳能CF60U相机拍摄）组成。每张参考照片代表神经纤维可见度的一个分数。正常人群样本的1941张照片的上半部分和下半部分区域分别与参考照片进行匹配。
双眼差异的标准差为2.76。与早期研究中实际重复测量的1.0至1.9的标准差相比，该标准差较为合理，表明该分级系统在1至25的总范围内具有良好的准确性。建立了照片分数与年龄之间的明确关系。
该照片分级系统证明了其在不同环境下的可行性。因此，使用照片参考集对视网膜神经纤维层照片进行评估可能有助于眼科医生和技术人员将视网膜神经纤维层摄影纳入其临床实践。
