Abstract

Aims-To evaluate the clinical features as well as the visual and anatomical outcome in eyes with magnetic posterior segment foreign bodies,to identify prognostic factors after removal using an electromagnet. Methods-The records of 40 patients with posterior segment foreign bodies were retrospectively reviewed for 6 years (1989-94). Post-traumaticcataracts and secondary retinal detachments were treated using conventional surgical techniques. Pars plana vitrectomy was used only for late complications. The mean follow up was 30 months (6-71). Clinical factors were studied using univariate analysis. Results-The most common findings before treatment of these 40 eyes were lens wound, hyphaema, vitreous haemorrhage, and retinal impairment. The foreign body was in the vitreous (85%) or minimally embedded in the retina (15%). Initial visual acuity was worse or equal to 20/40 in 70% of the cases. Subsequent to surgical treatment, a cataract was reported in 60% of the patients. Postoperative complications included retinal detachment (15%) andphthysis (5%). The prognosis was worse in cases with intraocular foreign body of largest diameter greater than or equal to 3 mm, an initialvisual acuity less than 20/200, or the presence of post-traumatic retinal detachment. Presence of initial intravitreous haemorrhage, hyphaema, or intraocular tissue prolapse did not appear to affect the prognosis. Conclusion-The long term visual acuity results indicated that wound repair associated with conventional magnet extraction in an emergency is a viable treatment for posterior segment magnetic foreign bodiesin this selected group. At the time of diagnosis, size of foreign body (<3 mm) and initial visual acuity greater than or equal to 20/200 were predictors of good visual outcome after primary magnetic extraction.
