The aim of this study was to establish anatomical and functional results of combined injuries of the anterior and posterior segment of the eye caused by penetration of the metallic foreign body.
Material and methods:
The group consisted of 25 eyes with penetrating injury caused by metallic intraocular body. The age at time of the injury in the group was 14–68 years (36.8 ± 10.9) and the average follow up period was 21.0 ± 10.7 months. All injuries were treated by means of suture of the entering wound with immediate or postponed treatment of the pathologic findings in both segments during one or more procedures. The metallic foreign bodies were extracted with forceps or endomagnetic device during the pars plana vitrectomy. Traumatic changes of the retina were treated by means of endodiathermy and endolaser. Silicone oil tamponade was performed, where indicated. The partial or total traumatic cataract was removed by phacoemulsification through the scleral admittance or by endophaco fragmentation with or without intraocular lens implantation.
The most common pathological findings were the penetrating wound of the cornea (72 %) and traumatic changes of the iris (56 %). The total cataract was present in 56 % of cases. In the posterior segment, vitreous hemorrhage was most frequent (36 %). Signs of endophtalmitis were present in 12 % of cases. The period between the primary suture and combined procedure at the anterior and posterior segment was mostly 5–14 days (56 %). In ten cases (40 %), the intraocular lens (IOL) was implanted, 9 times in the posterior and once in the anterior chamber. Out of the early postoperative complications, the fibrin in the anterior chamber was noticed most frequently (16 %), and out of the late ones, the retinal detachment (32 %) and proliferative vitreoretinopathy (24) were most common.
Anatomical and functional result of the combined injury with the foreign intraocular body depends not only on the choice of the surgical technique, but predominantly on the extent of the initial injury and risk of the present infection’s spreading.
