title: Retinal damages in turner workers of a factory exposed to intraocular foreign bodies.
abstract: Damages caused by an intraocular foreign body (IOFB) to the visual system, mainly the retina, mostly occur during certain occupational activities. Turners are among the laborers who are mostly exposed to IOFB. The aim of the present work is to survey the effect of an IOFB on the visual system, mainly the retina. Fifty laborers of a turner factory who were exposed to IOFB were selected. Electroretinography (ERG) was recorded in all the laborers. Beside these workers, 50 laborers with no incidence of IOFB were also selected. They were also tested using ERG. The results obtained in the two groups were compared together to search for the possible changes in the two groups. The ERG patterns of the case groups were found to be changed in comparison to the control group. The changes were observed in the area under the b-wave of the ERG pattern in the early stage of damage and in the late stages, the latency and amplitude of the ERG b-wave were also affected. Finally, from the result of the present study, one can conclude that ERG is a suitable technique to search for the retinal changes in the laborers exposed to IOFB.
