The current method of grading the optic disc cannot replace stereoscopic photography. The present method of describing the optic disc is misleading and does not supply as much information as could be provided. The proposed method adds both vertical and horizontal dimensions. It takes very little time to record and supplies both the reader and subsequent examiner with a more detailed description of the disc, cup, disc ratio.
目前对视盘进行分级的方法无法替代立体摄影。当前描述视盘的方法具有误导性，且提供的信息不如所能提供的那么多。所提出的方法增加了垂直和水平维度。记录所需时间极少，能为读者及后续检查者提供对视盘、视杯、视盘比更详细的描述。
