What does it mean when your iris moves?
Iridodonesis is a condition in which the iris (coloured part of the eye) vibrates during eye movements. Upon moving the eye rapidly, the iris can appear to ‘dance’, or ‘tremble’ (tremulousness). This occurs when the lens becomes partially detached (lens subluxation) from its suspensory ligaments.
What causes a rip in the iris of the eye?
Traumatic mydriasis: The result of blunt trauma to the eye, traumatic mydriasis are rips in the fabric of the iris that can also lead to unusually-shaped pupils. 10
When does a prolapse of the iris occur?
Iris prolapse can occur when the cornea is perforated due to any cause. In 1995, using flow mechanics and the Bernoulli principle, Allan provided a theoretical explanation of iris prolapse.With a corneal perforation, the aqueous humor rapidly escapes, and a relative vacuum is created in front of the iris, thus leading to iris prolapse.
What is the medical term for involuntary eye movements?
Nystagmus is the medical term used to describe involuntary eye movements. These eye movements may be side-to-side (lateral nystagmus), up and down (vertical nystagmus), or rotary.
Where is the Iris located in the eye?
Located between the cornea and lens, the iris is the pigmented, muscular curtain of the eye. It regulates the amount of light that gets into the eye.

What causes the pupil to move from the center of the iris?
What causes the pupil to move from the center of the iris? I’m not certain that I understand your question. My assumption is that you are asking about irregularly placed pupils, misplaced pupils or multiple pupils. Most commonly, that means that the pupil is not directly centered symmetrically with an equal rim of iris around the pupil.
