Is Anisocoria Genetic

Most often, the diameter difference is less than 0.5 mm, but it can be up to 1 mm. Babies born with different sized pupils may not have any underlying disorder. If other family members also have similar pupils, then the pupil size difference could be genetic and is nothing to worry about.

What is the most common cause of anisocoria?

Generally, anisocoria is caused by impaired dilation (a sympathetic response) or impaired constriction (a parasympathetic response) of pupils. An injury or lesion in either pathway may result in changes in pupil size.

Is pupil size genetic?

CONCLUSIONS Pupil size after mydriasis is largely genetically determined, with a heritability of up to 80%.
