Abstract

Anisocoria is the difference between the size of the two pupils, it is physiological in 20 percent of the population. When a patient presents with anisocoria, the necessity to rule out a serious condition, such as an pontine haemorrhage, often leads clinicians to obtain numerous tests, which are not always necessary. A logical and step wise clinical approach appreciating the mechanisms of anisocoria permits prompt recognition of true emergencies and often obviates the need for invasive and costly testing.
