Overview

Background:
To evaluate the application of the available diagnostic proceduresin intraocular foreign bodies impacted in the posterior segment of the eye.Materials and methods: Between 1989 - 1993 were treated 51 patients and between1994 - 1998 were treated 74 patients with intraocular foreign bodies in the posterioreye segment at the Department of Ophthalmology, Medical faculty of the ComeniusUniversity in Bratislava. It was evaluated: time of the first medical examination,cause of the injury, time of the right diagnostic and used ancillary testings. In thesecond period (prospective study) was evaluated also foreign body trajectory inthe posterior segment of the eye. The influence on the final visual acuity wasevaluated in no proper diagnosed patients.Results: 50.9 % of patients in the first period and 55.9 % of patients in the secondperiod were injured while at work. Foreign body was metallic in 96 % and 94.7 %respectively. In the first period 12 patients were injured by various explosionsand in the second period 16 patients were injured by working with some circula-ting tools. The most common ancillary testing was plain film testing and Comberglocalisation. In the second period was intraocular foreign body trajectory defined as indirect in 24 eyes (32 %). The foreign body achieved its final intraocularposition after simple or double contact with the retina. Foreign body was unpro-perly diagnosed in 14 patients. The final visual acuity was negative influenced bythis fact in 8 patients.Conclusions: A history and ocular examinationare are still most important indiagnosis of the penetrating eye injury with intraocular foreign body. The basicancilary testing is simple plain film. Ultrasonography is helpful in diagnosis ofother intraocular pathological changes. In justified cases is also possible toperform computed tomography. The peroperative intraocular diagnostics is veryimportant for treatment of the all injured intraocular structures.
