Anisocoria is a common condition, defined by a diameter difference of 0.4 mm or more between the sizes of the pupils of the eyes. [2] Anisocoria has various causes: [3] Physiological anisocoria: About 20% of the population has a slight
Physiological anisocoria is when human pupils differ in size. It is generally considered to be benign, though it must be distinguished from congenital Horner's syndrome , pharmacological dilatation, or other conditions connected to the sympathetic nervous system . [ 1 ]
Anisocoria is absent. A Marcus Gunn pupil is seen, among other conditions, in unilateral optic neuritis. [4] It is also common in retrobulbar optic neuritis due to multiple sclerosis but unreliable in bilateral optic neuritis. [4] [5]

This is a list of notable people who have been documented as having heterochromia iridis, a condition when the irises have different colours. People who are frequently mistakenly thought to have heterochromia are not included, but may be listed in the Notes section.
Horner's syndrome, also known as oculosympathetic paresis, [1] is a combination of symptoms that arises when a group of nerves known as the sympathetic trunk is damaged. The signs and symptoms occur on the same side (ipsilateral) as it is a lesion of the sympathetic trunk.
Mydriasis is the dilation of the pupil, usually having a non-physiological cause, [3] or sometimes a physiological pupillary response. [4] Non-physiological causes of mydriasis include disease, trauma, or the use of certain types of drugs.
