Fig. 1 Finite element analysis (FEA) correlated with motion analysis of impacts on human eyes. A–C. BB, moving right to left at 92.0 m/s (301.8 ft/s; 0.58 J) impacting a human cadaver eye held in an artificial orbit with clear gelatin. The sequence will be continued in the section on BBs to follow. D–F. FEA of the BB impact to a point just before globe penetration. G–I. Baseball, moving left to right at 41.2 m/s (92.2 mph; 124.3 J) impacting a human cadaver eye held in an artificial orbit with clear gelatin. Note globe rupture (dark area) at equator of the globe starting in (H) and enlarging in (I) See Figure 5 for the baseball rebound. J–L. FEA of the baseball impact to a point just before globe penetration. This FEA model has potential usefulness as a simulation tool for ocular injury and it may provide useful information for developing protective measures against sports, industrial and traffic ocular injuries.
