Anisocoria in the presence of confusion, decreased mental status, severe headache, or other neurological symptoms can forewarn a neurosurgical emergency. This is because a hemorrhage, tumor, or other intracranial mass can enlarge to a size where the third cranial nerve (oculomotor nerve) is compressed, resulting in uninhibited dilatation of the ...

Anisocoria caused by tropicamide instilled into the subject's right eye only. Tropicamide is an antimuscarinic drug that produces short acting mydriasis (dilation of the pupil) and cycloplegia [7] when applied as eye drops. It is used to allow better examination of the lens, vitreous humor, and retina.

The main characteristic that distinguishes physiological anisocoria is an increase of pupil size with lower light or reduced illumination, such that the pupils differ in size between the two eyes. At any given eye examination, up to 41% of healthy patients can show an anisocoria of 0.4 mm or more at one time or another.
Mechanical anisocoria refers to anisocoria, a common eye condition in which the two pupils differ in size, that is the result of damage to the iris dilator muscle, which may be caused by trauma, angle-closure glaucoma, surgery such as cataract removal, or uveitis (inflammation of the eye).
Of all the children in the world, about 19 million of them are estimated to be visually impaired or blind. [28] There is evidence that the prevalence of visual impairment or blindness in children is much higher as many studies use data that are at risk bias and miss many children who fall under multiple categories of disadvantage (i.e. female ...
