What is the reason for the different pupils?

Heterocoria may be caused by eye trauma, glaucoma, abnormal pupils, genetics, etc. Details are as follows:

1. Eye trauma

When the eye is hit by external impact, it may lead to tympanic membrane damage and heterochromatic binocular phenomenon.

2.

Glaucoma occurs, which will lead to sustained increase in intraocular pressure, which will seriously cause iris pigment loss and induce disease.

3. Pupil abnormality

If the pupil is abnormal, it may lead to iris damage and cause heterocoria.

4. Inheritance

If there is heterocoria in the family, it may carry genetic genes and cause heterocoria.
