[Intraocular foreign bodies of a non-magnetic nature. Retrospective study]

The analysis of 243 cases with perforative eye injuries with intraocular foreign bodies was performed. Of them 183 were caused by non-magnetic and 60 by magnetic foreign bodies. The increased number of perforative injuries caused by non-magnetic foreign bodies was observed (71,2%). A large number of non-magnetic foreign bodies contained copper (76%). In 74% cases non-magnetic foreign bodies were found in the posterior eye segment. By introducing modern diagnostical and surgical methods (1976) the percentage of removed non-magnetic foreign bodies is significantly higher (93%) compared to the previous period (1961-1975).
