[Problems in diagnosis of intraocular foreign bodies in the posterior eye segment].
BACKGROUND
To evaluate the application of the available diagnostic procedures in intraocular foreign bodies impacted in the posterior segment of the eye.


METHODS
Between 1989-1993 were treated 51 patients and between 1994-1998 were treated 74 patients with intraocular foreign bodies in the posterior eye segment at the Department of Ophthalmology, Medical faculty of the Comenius University 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 the second period (prospective study) was evaluated also foreign body trajectory in the posterior segment of the eye. The influence on the final visual acuity was evaluated in no proper diagnosed patients.


RESULTS
50.9% of patients in the first period and 55.9% of patients in the second period 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 explosions and in the second period 16 patients were injured by working with some circulating tools. The most common ancillary testing was plain film testing and Comberg localisation. In the second period was intraocular foreign body trajectory defined as indirect in 24 eyes (32%). The foreign body achieved its final intraocular position after simple or double contact with the retina. Foreign body was unproperly diagnosed in 14 patients. The final visual acuity was negative influenced by this fact in 8 patients.


CONCLUSIONS
A history and ocular examinationare are still most important in diagnosis of the penetrating eye injury with intraocular foreign body. The basic ancilary testing is simple plain film. Ultrasonography is helpful in diagnosis of other intraocular pathological changes. In justified cases is also possible to perform computed tomography. The peroperative intraocular diagnostics is very important for treatment of the all injured intraocular structures.
