Risk Functions for Human and Porcine Eye Rupture Based on Projectile Characteristics of Blunt Objects

Blunt projectile impacts to the eye can occur in automobile crashes, sporting impacts, and military events. This study developed injury risk functions for globe rupture of both human and porcine eyes from blunt projectile impacts. The first part of this study was an analysis of data from 57 eye impact tests reported in the literature. In the second part, 126 projectile tests were performed on human and porcine eyes. Projectiles included blunt aluminum projectiles, BBs, foam pellets, Airsoft pellets, and paintballs. In the third part of the study, the data were pooled for a total of 183 eye impact tests, 83 human and 100 porcine, and were analyzed to develop the injury risk criteria. Porcine eyes were found to be significantly stronger than human eyes in resisting globe rupture. The results presented in this paper are useful in estimating the risk of globe rupture when projectile parameters are known. They can also be used to validate computational eye models.
