An iron foreign body was placed intravitreously in 19 rabbits. In 11 animals the foreign body was surgically removed after approximately 13 weeks and in 8 animals the extraction was performed after about 2 weeks.

Postoperative complications were encountered in 7 animals. The ERG changes of the remaining 12 animals were recorded over a 56 week period after foreign body removal.

All experiments used one eye as the experimental eye and the fellow eye as the control. The a- and b-wave amplitudes of the experimental eye were expressed in % of the control eye.

The results show that removal of the foreign body does not improve the ERG nor prevent its further deterioration.
