Introduction
An irregularly shaped pupil may be caused by conditions such as iridocyclitis, glaucoma, or penetrating corneal injury. Iridocyclitis is a common ophthalmic disease, also known as anterior uveitis. It typically results from direct invasion of the iris and ciliary body by bacteria, fungi, or other pathogens, leading to inflammation. Symptoms include eye pain, photophobia, and decreased vision. Prompt medical treatment at a hospital is necessary.

1. Iridocyclitis: Iridocyclitis is a common ophthalmic condition, also known as anterior uveitis. It typically results from direct invasion of the iris and ciliary body by bacteria, fungi, or other pathogens, leading to inflammation. Symptoms include eye pain, photophobia, and decreased vision. As the condition worsens, posterior synechiae (adhesions between the iris and lens) may develop, causing an irregular pupil shape. Treatment under medical guidance may include oral medications such as levofloxacin hydrochloride capsules or cefuroxime axetil tablets.
2. Glaucoma: Glaucoma is a disease characterized by optic nerve atrophy, visual field defects, and reduced vision. During an acute attack of glaucoma, paralysis of the pupillary sphincter muscle may occur, resulting in pupil dilation and an abnormally shaped pupil. Treatment under medical supervision may involve the use of eye drops such as brinzolamide ophthalmic solution or latanoprost ophthalmic solution.
3. Corneal Penetrating Injury: A corneal penetrating injury is usually caused by sharp objects piercing or cutting through the cornea, resulting in full-thickness laceration and often accompanied by damage or protrusion of intraocular tissues. This may lead to rupture or paralysis of the pupillary sphincter muscle, thereby causing an irregular pupil shape. After eye injury, avoid rubbing the eye, as this may exacerbate prolapse of ocular contents, and do not rinse the eye with large amounts of water. Instead, keep the eye gently closed and seek immediate medical attention at the nearest hospital.
In addition, irregular pupils may also result from congenital developmental abnormalities, which are generally not a cause for concern. If any eye discomfort occurs, prompt medical evaluation and treatment are recommended.
