Iridodialysis is a separation of the iris root from its attachment at the eye's internal wall. The tear usually follows blunt trauma but can also appear after certain surgeries. The gap allows light to enter from an abnormal angle, causing glare or double vision. Some people show a visible notch or irregular pupil shape. Treatment depends on symptoms and the size of the tear.
read more about iridodialysis ...Blunt impact to the eye is the most common cause. Surgical manipulation during cataract or glaucoma procedures can also detach the iris root. Sudden pressure changes inside the eye may contribute in rare cases. Tissue weakness from prior eye disease increases risk. Understanding the cause helps determine the best repair approach.
People may notice glare or light streaks due to the abnormal opening. The pupil may appear irregular or displaced. Double vision in one eye can develop when the tear affects light entry. Some experience pain at the time of injury. Symptoms vary based on the tear's size.
Slit lamp exam reveals the detached iris edge. Doctors check pupil shape and reactions. Gonioscopy helps view the angle where the iris normally attaches. Imaging is rarely needed but can document severe cases. Diagnosis guides whether repair is necessary.
Small, symptom-free tears may be monitored. Larger tears may require suturing the iris back to its attachment. Contact lenses can reduce glare temporarily. In severe trauma, combined repairs may be needed. Follow-up checks for pressure changes and stability.
No. The iris does not reattach by itself.
Only if the tear is large or light enters through the gap.
Repairs tend to remain stable long term.
Seek care after eye injury or if glare becomes noticeable.
