Pars plana vitrectomy in ocular injury with intraocular foreign body.

BACKGROUND

We evaluated 70 cases of ocular injuries with intraocular foreign bodies to determine the results of surgical management.

METHODS

The site of penetration was cornea in 58 (82.9%), sclera in 8 (11.4%), and limbus in 4 (5.7%) eyes. The foreign body was in the vitreous in 40 (57.1%) and embedded in the retina in 30 (42.9%) cases. Before pars plana vitrectomy, the most common findings were found to be lens perforation (77.1%), vitreous hemorrhage (45.7%), endophthalmitis (20%), hyphema (4.3%), and retinal detachment (2.9%).

RESULTS

After pars plana vitrectomy, visual acuity improved in 39 (55.7%), did not change in 19 (27.2%), and decreased in 8 (11.4%) cases. We observed secondary glaucoma in 11 (15.7%), retinal detachment in 10 (14.3%), and phthisis bulbi in 3 (4.3%) cases postoperatively.

CONCLUSION

Pars plana vitrectomy is found to be an effective therapeutic approach in removing intraocular foreign bodies, but the preoperative and postoperative complications determine the visual outcome.
