iridodialysis commonly occurs secondary to blunt ocular trauma,1 penetrating ocular trauma , and intraocular surgical procedures . in the cases of small iridodialysis
the upper eyelid covers iridodialysis superiorly and prevents symptoms . however , temporal iridodialysis is usually symptomatic .
in addition to visual problems such as diplopia , glare , and photophobia , cosmetic problems such as polycoria and ectopic pupil might occur due to large iridodialysis .
a number of surgical techniques have been described for the repair of iridodialysis.245678 we describe a novel 
cobbler 's technique  for repairing iridodialysis in the right eye of an 18-year - old patient .
following peribulbar anesthesia , a fornix - based localized conjunctival peritomy ( 611 oclock ) was performed in the right eye of a patient with traumatic iridodialysis extending from 7 oclock to 10 oclock position in the inferotemporal quadrant [ figure 1 ] .
a partial thickness scleral tunnel was created 1.5 mm from the limbus along the extent of the iridodialysis .
a limbal paracentesis was created with a stiletto knife at the 2 oclock position , and intracameral pilocarpine was injected into the anterior chamber to place the iris tissue on the maximal stretch .
the 26-gauge needle was passed through the paracentesis and the 10 oclock end of the scleral groove engaging the root of the iris .
the needle was withdrawn into the anterior chamber and taken out at the 9.30 oclock position engaging the root of the iris again .
the prolene suture was pulled out forming a loop through which the free end of the suture was passed to lock the loop .
this step was repeated multiple times until multiple loops laid over the scleral bed [ figure 2 ] .
these loops were then tied [ figure 3 ] and the conjuctival peritomy was closed using 8 - 0 vicryl sutures .

functional symptoms , such as glare and monocular diplopia , result from the polycoria of a pseudo - pupil created by the iridodialysis .
typically , these complaints are most commonly seen when iridodialysis is located in the nasal , temporal , or inferior quadrants , as was seen in our patient .
cosmetic deformities associated with iridodialysis can affect self - esteem adversely and thus have a major psychosocial impact on the patient.910 various methods for surgical repair of iridodialysis2345678 have been described in literature .
most of these procedures require more surgical maneuvers and anterior chamber is often not stable while repairing large iridodialysis .
the advantages of  cobbler 's technique  for repairing iridodialysis as described above include : ( 1 ) it is performed through a small paracentesis wound ; ( 2 ) the anterior chamber remains stable throughout ; ( 3 ) multiple sutures can be passed without withdrawing the needle from anterior chamber ; ( 4 ) large dialysis can be repaired easily ; ( 5 ) the shape of the iris can be controlled ; ( 6 ) only one suture knot is required at the end of the incision which can be easily be buried within the sclera groove minimizing the likelihood of late suture erosion . our novel  cobbler 's technique  for iridodialysis repair allows a maximally functional and cosmetic result .
this technique was named  cobbler 's technique  since it bears great similarity to the way a cobbler repairs shoes .
 we describe a novel  cobbler 's technique  for iridodialysis repair in the right eye of a patient aged 18 years , with a traumatic iridodialysis secondary to open globe injury with an iron rod . 
 our technique is simple with easy surgical maneuvers , that is , effective for repairing iridodialysis . 
 the  cobbler 's technique  allows a maximally functional and cosmetic result for iridodialysis .
