Gliederung

Text

Objective

To determine the optimal approach to the removal of retained encysted foreign bodies embedded in the posterior pole in order to decrease the risk of proliferative vitreoretinopathy and traction retinal detachment). Positive effect of the laser coagulation around foreign body was noted on the prevention of the traction retinal detachment, proliferative vitreoretinopathy, bleeding and metallosis.

Methods

From 2000 through 2005 we followed 71 patients with the foreign bodies embedded in the posterior pole All the injuries occurred in male patients, with a mean age of 38,2 (range 17 to 58). Most of the injuries occurred in the work place. Post - trauma time interval ranged from 1-2 months to 14 years. Preoperative examination in all patients included the standard methods: visual acuity and visual fields testing, biomicroscopy, indirect binocular ophthalmoscopy. Ultrasonic ocular examination was performed in all 71 patients using Humphrey A/B Scan system 835 with 10-12.5 MHz frequencies and 40 or 60° scan angle. Computed tomography was used in 71 patients with posteriorly located IOFB embedded in the retina. Preoperative (3 session) and late postoperative (1- 3 session) barrier laser coagulation around foreign body (FB) was performed using laser ophthalmic coagulator І Visulas - Argon II. І Intraoperatively we used І Nydec І diode laser DC - 3000.

Results

Transvitreal FB removal following endolaser was performed in 63 patients. For our opinion pars plana vitrectomy prior to IOFB removal may break the state of “pathologic balance” in the injured eye, especially in the presence of the clear vitreous body. Complications: retinal detachment developed in 3 patients. In 8 patients we performed pars plana vitrectomy with one-stage endolaser without attempts of FB removal. All patients underwent postoperative laser coagulation 1 - 2 month's periods.

Conclusions

Combined and consistent argon and diode laser coagulation increases the safety of retained FB removal from posterior pole and contributes to the maintenance and improvement of visual functions in 90.9% of patients.
