The clinician involved in cataract assessment is often faced with a deterioration in visual performance which may or may not be totally attributable to the cataract. Neural changes may occur concurrently and contribute toward the reduced performance. This paper reviews the methods which attempt to discriminate between changes due to cataract development and changes produced by neural degeneration. New techniques have been developed with more emphasis on quantitative rather than qualitative assessment. These techniques are discussed critically with particular reference to their ability to distinguish between the contributions of optical and neural change. This has particular application in predicting the visual outcome after cataract surgery.
参与白内障评估的临床医生常常面临视力下降的情况，这种视力下降可能完全归因于白内障，也可能并非完全如此。神经变化可能同时发生，并导致视力下降。本文综述了一些方法，旨在区分白内障发展引起的变化和神经退行性变产生的变化。已经开发出了新技术，更侧重于定量评估而非定性评估。本文对这些技术进行了批判性讨论，特别提及了它们区分光学变化和神经变化贡献的能力。这在预测白内障手术后的视觉效果方面具有特殊应用。
