PURPOSE:

To study the results of surgical management of intraretinal foreign bodies (IRFBs) and to identify the factors influential on anatomic and visual outcomes.

METHODS:

The records of patients who underwent vitrectomy and IRFB removal from 1993 to 2002 were reviewed. The effects of different preoperative and intraoperative factors on the visual and anatomic outcomes were evaluated.

RESULTS:

Thirty eyes of 29 patients were included in this study. All patients were male with the age range of 8 to 54 years (average: 28.3 years). The cause of trauma was explosion in 6 eyes (20%) and hammering in 24 eyes (80%). The mean follow-up period was 20.3 months. The IRFBs were ferromagnetic in 25 cases (83.4%). Barrier laser photocoagulation was performed before surgery in 7 eyes. Foreign bodies were removed with intraocular forceps in 17 eyes (56.7%) and with magnet in 13 cases (43.3%). Retinal breaks developed posterior to the sclerotomies in 9 eyes (30%). The retina was attached in all cases at the last follow-up examination. In 21 of 30 eyes, visual acuity improved after surgery. The final visual acuity was 20/40 or better in 12 eyes (40%) and 20/200 or better in 22 eyes (73.3%). There was a positive relationship between preoperative and postoperative visual acuity of 20/40 or better. Macular pucker had a negative relationship with postoperative visual acuity of 20/40 or better.

CONCLUSION:

Despite complex nature of IRFBs, the anatomic and visual results of surgical management have improved in these cases due to progress in surgical techniques and better understanding of the potential complications.
