Combined anterior and posterior segment surgery in the treatment of penetrating eye injuries with small intraocular foreign body

Abstract

Objective To investigate the clinical efficacy of combined anterior and posterior segment surgery in early treatment of penetrating eye injuries with small intraocular foreign body. Methods Twenty-two eyes of 22 patients suffered penetrating eye injuries with small intraocular foreign bodies underwent the combined operations of anterior and posterior eye segment 2-4 days after emergent debridement and suturing and according to their conditions different surgical procedures were preformed. Anterior segment surgery included anterior chamber forming, iris suture laceration, cataract extraction and intraocular lens implantation and posterior segment surgery included vitrectomy, foreign body removal, retinal laser photocoagulation around the injury site and C3F8 gas or silicone oil tamponade. The surgery efficacy and the complications were analyzed from 3months to 12 months. Silicone oil was removed 4-5month after operation. Results Intraocular foreign bodies were removed in once operation in all cases. All the patients got the intraocular lens implantation at the same time during the surgery. No serious complication happened, such as endophthalmitis, intraocular lens shift, uveitis, retinal detachment, choroidal detachment or secondary glaucoma. All the cases got the best corrected visual acuity improved from light perception -0.1 before operation to 0.05-0.8. Conclusion Combined anterior and posterior segment surgery in early treatment of penetrating eye injury with small intraocular foreign body can achieve good clinical efficacy.
