ABSTRACT

Ten pafients with iron-containing intraocular foreign bodies were undergone electroretinographic test at Department of Ophthalmology, Siriraj Hospital between November 1992 and March 1995. The changes varied from normal, supernormal, negative, subnormal to extinguished ERG. These changes were not correlated with the harboring time of the intraocular foreign bodies. The electroretinographic test was useful for evaluating retinal function in siderosis bulbi and had a prognostic value. A careful test and interpretation should be carried out in this group of patients.
