在青光眼患者的诊断过程中,视神经乳头局部解剖结构的观察分析起着重要作用。临床实践中常用的方法就是记录视神经乳头的表现,包括描述图形及立体彩色照相。然而,由于这些方法受主观解释及定性特性所制约,不适于辨别那些虽然较小、但却是重要的视神经结构改变。1984年西德Rodenstock 仪器公司研制成一种可用于检查视神经乳头局部解剖结构的新仪器——视神经乳头分析仪(OpticNerve Head Analyzer,ONHA)。该仪器采用可调谐的单色光照明,配有同时相立 In the diagnosis of glaucoma patients, the optic nerve head anatomy of the local anatomy and analysis play an important role. Commonly used in clinical practice is to record the performance of the optic nerve head, including the description of graphics and three-dimensional color photography. However, since these methods are subject to subjective interpretation and qualitative characterization, they are not suitable for discriminating those small but important optic nerve structural changes. 1984 Germany Rodenstock Instruments developed a new device for examining the local anatomy of the optic nerve head - OpticNerve Head Analyzer (ONHA). The instrument uses tunable monochromatic lighting, with simultaneous phase
