In the examination of the human optical system, the diagnosis of an eye defect known as the Relative Afferent Pupillary Defect (RAPD) can be concluded through qualitative tests performed by an ophthalmologist. He/She would manually observe the reaction of both pupils, while repeatedly shifting a light source quickly between them. A patient is likely to suffer from RAPD if stimulating the affected eye causes a slight dilation in both eyes, instead of a constriction. In this regard, the determination of the said defect is pivotal in the detection of various conditions, such as optic nerve tumour or brain death. As with any other form of cancer, early detection is crucial in order to have a better chance of curing it.
