Aim: The aim of this study was to establish the correlation coefficient between given parameters of the entering wound and final position of the metallic intraocular foreign body. Material and methods: fifty patients (50 eyes) with a penetrating injury of the eye and present metallic intraocular foreign body were included in this study. Clinically found data of the entering wound and final position of the intraocular foreign body (IFB) as well were transformed with a computer model into the three-dimensional parameters. Both chirurparameters were statistically evaluated by means of correlation analysis, and correlation coefficient and determination coefficient were calculated. Results: The extent of correlation between two variables is called correlation coefficient. The coefficient values range between -1 to +1. The closer is the calculated value to ranges (to -1 or to +1) the more are the two variables more correlated. The coefficient of determination values range from 0 to +1. The closer the results are to +1, the better the model describes the dependence between the two variables. The results obtained by means of correlation analysis were for the correlation coefficient 0.454, and for the coefficient of determination 0.6411 respectively. Results: Results of the correlation analysis show that the knowledge of coordinates of the entering wound has no prediction value for final position of the foreign body in the eye. These two variables are not correlated and so the accurate final position of the foreign body cannot be predicted. The final position of the intraocular metallic foreign body is probably influenced by biophysical factors not included in this study.
