The Cases of Penetrating Eye Injuries with Large Intraocular Foreign Body

Overview

Aim:
Three consecutive cases of penetrating eye injuries complicated with large (size 9-12 mm) intraocular foreign body are presented as such.

Patients and Methods:
The initial findings, management, surgical procedures and final anatomical and functional outcomes of each particular case are given. Corneal entrance laceration was seen in all three patients. Second scleral full-thickness eye wall laceration was found just posterior to the horizontal muscle insertions in two eyes. Full-thickness exit posterior eye wall laceration obturated with foreign body was diagnosed in one case. This metallic foreign body projected into posterior orbit. Two eyes were injured with metallic radio opaque foreign body. Glass fragment was removed from posterior segment of the eye in one patient. Following primary wound closure pars plana vitrectomy was performed to remove all posterior segment intraocular foreign bodies.

Results:
Silicone oil was used to fill the vitreous cavity at the end of the surgery in two eyes. Gas bubble (perfluoropropane, C₃F₈) was injected into the vitreous space at the end of the vitrectomy in one eye. The authors observed following complications: vitreous cavity haemorrhage, traumatic cataract formation, cystoid macular oedema and peripheral stationary traction retinal detachment.

Conclusion:
Good anatomical results and restoration of good visual functions of injured eye were achieved in all patients despite some inferior initial prognostic factors.

Key words:
large intraocular foreign body, pars plana vitrectomy, laceration of the eye
