ABSTRACT
To see properly you need to have normal eyes, eye movements and central visual
connections. Your approach to the examination thus involves determining which of
these three components has failed. The range of possibilities with this introduction
is wide and includes: blindness in one eye, bitemporal hemianopia, homonymous
hemianopia and IIIrd, IVth or VIth nerve palsies. Patients with pupillary abnormalities
and nystagmus will also be considered in this chapter. Many people experience difficulty
in testing the eyes, and some time will be spent in describing techniques which are useful.
