the eye itself, such as a corneal abrasion or hyphema Injury to the eye from a high-speed soft object such as a tennis ball will often result in a hyphema Hard objects striking the orbit at a high speed, such as a baseball or a fist, are likely to result in an orbital blowout fracture High-impact mechanisms, such as those encountered when the face strikes the dashboard in a motor vehicle collision, are likely to result in complex orbital and midface fractures
