Introduction. Penetrating injury is characterized by the existence of entry
wound only, and it can be with or without an intraocular foreign body (IOFB).
IOFB can lead to a mechanical injury of the eye and to cause infection or to
manifest other toxic effects on intraocular structures. Iron and copper can
dissolve and cause siderosis, i.e. chalcosis of the eye. Ocular siderosis is
diagnosed by clinical and electroretinogram (ERG) findings. Outline of Cases.
The first patient was a 37yearold male who was injured by a metal foreign
body. He presented at the Clinic two years after the injury. Visual acuity of
the right eye (VOD) on admission was VOD=L+P+ (light projection). Pars plana
phacovitrectomy with IOFB extraction was done. Visual acuity on discharge was
VOD=3/60 cc + 7.50 Dsph=0.2. The second patient was a 55yearold male who
presented at the clinic 18 months after injury. On admission visual acuity in
his left eye was VOS 1/60. Pars plana phacovitrectomy with IOFB extraction
was done. Visual acuity on discharge was VOS=0.7 through the stenopeic slit.
Conclusion. In penetrating injuries caused by a metal IOFB pars plana
vitrectomy with IOFB extraction is indicated. In cases with IOFB, when visual
acuity is preserved, the lens is transparent, while the eye is without signs
of infection, urgent pars plana vitrectomy is not necessary. Such patients
need regular followup with obligatory ERG findings.
