The study on the effect of extraction of eyeball wall foreign bodies with vitrectomy

Objective To evaluate the clinical effect of extraction of eyeball wall foreign bodies with vitrectomy. Methods A total of 21 cases (21 eyes) of eyeball wall foreign bodies underwent vitrectomy. Laser photocoagulation and suitable intraocular tamponade were used when needed. Results Foreign bodies were completely taken off from 20 eyes. Foreign body in one eye was forced out of the eyeball and left retrobulbar.Retinas were reattached in 17eyes, while retinal detachment occurred in 4 eyes. After surgery, the best corrected visual acuity improved in 16 eyes, remained in 3 eyes, and decreased in 4 eyes. Conelusions Extraction of eyeball wall foreign bodies with vitrectomy is safe. It is effective to prevent retinal detachment by excising the vitreous completely and checking up the peripheral retina with episcleral indentation carefully.
