Iris defects can be congenital, traumatic or iatrogenic in origin and affect either the base of the iris or the stroma including the pupillary margin. A differentiation must be made between the occlusion of iridodialyses, by which the detached iris must be fixed on the sclera and defects of the stroma of the iris where parts of the iris are combined to cover the defect. A wide variety of suture techniques have been suggested over the years for iridoplasty to cover defects. Nowadays it is normal to use iris sutures with a closed anterior chamber, which have all the advantages of minimally invasive surgery.
