Anisocoria indicates unequal pupil sizes. It is relatively common, and causes vary from benign physiologic anisocoria to potentially life-threatening emergencies. Thus, thorough clinical evaluation is important for appropriate diagnosis and management of the underlying cause.

2021年3月29日 · Anisocoria, or unequal pupil sizes, is a common condition. The varied causes have implications ranging from life threatening to completely benign, and a clinically guided history and examination...

2023年7月31日 · Causes of anisocoria (unequal pupil size) range in seriousness from a normal, physiologic condition to one that is immediately life threatening. When a patient presents with anisocoria, the fear of a serious condition, such as an intracranial aneurysm, often leads clinicians to obtain numerous tests, which are not always necessary.

2023年8月8日 · Anisocoria is a condition characterized by unequal pupil size. The etiology of anisocoria is complex, ranging from benign to potentially life-threatening causes. Potential etiologies of anisocoria include systemic drug use, topical ophthalmic drug use, headaches, trauma, ophthalmologic diseases, and autonomic ganglion pathology.

Anisocoria, or unequal pupil sizes, is a common condition. Approximately 20% of the normal population have physiologic anisocoria. However, pathologic anisocoria indicates disease of the iris, parasympathetic pathway or sympathetic pathway.

2021年10月11日 · Anisocoria is present when an individual's pupils differ in size. If a person's pupils are symmetric there is said to be isocoria. The prevalence of transient physiological anisocoria of >0.4 mm is found in up to 20% population. However persistent anisocoria seems to be rarer, in the same study it was only found in 3% subjects 1.

In addition, the differential diagnosis for anisocoria continuously expands with identification and improved understanding of causal disease processes. Summary: The present article discusses an approach to the classic anisocoria diagnostic algorithm modified by current knowledge from the most recent literature.

A difference in the size of the pupils (anisocoria) is a frequent finding on physical examination. While often a cause for alarm, it is not uncommonly physiologic. In this chapter, we begin by reviewing the innervation of the iris sphincter and dilator muscles.

Unequal pupils (anisocoria) may be physiological, pathological or pharmacological. Importantly, anisocoria can indicate underlying disease of the eye, orbit, brain, neck or chest. Examination of the pupils is therefore a crucial part of any eye examination.

2020年1月27日 · However, the most concerning condition in the differential diagnosis of a child with anisocoria is Horner syndrome, a loss of the sympathetic tone to the eye (oculo-sympathetic paresis). The typical presentation of Horner syndrome includes unilateral ptosis and miosis.
