Diagnosis and Management of Posterior Segment Intraocular Foreign Bodies.
Pak J Ophthalmol Jan ;15(2):48-56.

A review of posterior segment intraocular foreign bodies (IOFBs) in 32 eyes of 32 patients is presented. All of the foreign bodies were managed by the author during the period from 1992-1997 at AI-Shifa Trust Eye Hospital, Rawalpindi. All the patients were young, between the ages of 18 and 43 years. All were males. Visual acuity at the time of presentation was in the range of perception of light (PL) to 6160 with only one eye having 616 vision. Most of the injuries occurred at work. Fourteen 143.8%1 of the eyes had accompanying corneal, comeoscleral or scleral perforations. Twenty-seven (84.37%) of the patients had associated vitreous haemorrhage varying from mild to severe. An associated retinal detachment was present in 11 eyes (34.37%), while one developed a detachment during foreign body removal. Thirty-one eyes had single foreign bodies, while one eye had two intraocular foreign bodies. Seven (21.9%) IOFBs were in the vitreous. Twenty-five (78%) IOFBs were embedded In the retina and the choroid. Twenty-seven (84.4%) of the foreign bodies were metallic but not necessarily magnetic. In three cases the foreign bodies were stone pieces and in 2 cases glass fragments. Breaks requiring buckling were present in 6 cases, while in 5 cases the breaks were too posterior and silicone oil tamponade was used. Four of the IOFBs were associated with severe localized retinal edema. All except three were removed under direct visualization following a three-port pars plana vitrectomy. Three of the foreign bodies were removed with an external magnet. The final visual acuity after one year of follow-up In the salvaged eyes was in the range of perception of light to 6112 with only one eye retaining 616 vision. Causes of decreased vision were cataracts, macular problems caused by injury or retinal detachment and epiretinal membranes (ERM). Two eyes developed endophthalmitis and could not be salvaged even after removal of the foreign bodies. Three eyes (9.37%) developed late retinal detachment with severe PVR and could not regain useful vision.
