![]() Iritis may be caused by an eye infection, trauma, and underlying inflammatory disease. It is a form of uveitis, or the inflammation of the eyes, characterized by photophobia, eye redness, pain, constriction of the pupil on the affected eye, and inflammatory cells in the eye. Pathologic anisocoria causes differences in pupil sizes due to underlying conditions such as: Motion sickness and nausea from chemotherapy medications along with some glaucoma eye drops such as transdermal scopolamine patches can also cause anisocoria. Selective serotonin reuptake inhibitors (SSRIs) used to treat depression have been identified as potential causes of pharmacologic anisocoria. This is inequality in pupil size that occurs as a side effect of a medication. This type of anisocoria may also be caused by congenital anomalies in the structure of the iris which include:Īniridia – complete or partial absence of the iris in one eyeĮctopic pupil – displacement of the pupil and lensĬoloboma – gap in the iris which gives off a “keyhole” or “cat-eye” appearance Mechanical anisocoria is a result of damage to the iris or its surrounding structures caused by trauma, tumors, complications of eye surgery, angle-closure glaucoma, uveitis, iritis, and other inflammatory conditions. Simple anisocoria may be intermittent, constant, or sometimes goes away on its own – although the exact cause is still unknown. The difference in pupil size is approximately 1 mm or less and both pupils respond normally to light. It is a harmless condition that affects around 20% of the population. Simple anisocoria, also known as essential anisocoria or physiologic anisocoria, is the most prevalent type of anisocoria. However, if your anisocoria happens all of a sudden, this can be a symptom of a serious condition. In common cases, anisocoria is usually benign and does not need serious concern. ![]() Anisocoria is a condition where the two pupils are unequal in size and may not respond normally to light.
