Evaluating the Risk of Eye Injuries: Intraocular Pressure During High Speed Projectile Impacts

Abstract: Intraocular pressures dramatically above normal physiological pressure were observed for high speed projectile impacts. These pressure data provide critical insight to chronic ocular injuries and long-term complications such as glaucoma and cataracts.

“…[45]. Recently, Alphonse et al [46] calculated the injury risk for an increased IOP using correlation between the projectile normalized energy and the IOP by Duma et al [47]. The calculated percentage of injury risks corresponding to the maximum IOP value 0.42 MPa for our simulation are around 98%, 14%, 0%, 0%, 0.02% respectively, for corneal abrasion, hyphema, lens dislocation, retinal damage and globe rupture.…”

“…Ms Alphonse and colleagues stated, "Although it is suggested that the pressure wave (ie, blast overpressure) can cause eye injury (scleral bleeding and globe rupture), there is no clear evidence to support this." 1 We are surprised that the described experiment did not induce these types of injuries.…”

“…Previous research has shown that projectiles can cause serious eye injuries due to considerable deformation, penetration, or perforation of the eye. [1][2][3] Our experiments were designed to evaluate overpressure (ie, pressure wave) from a firework explosion as a potential eye injury mechanism.…”

“…A bag of lactated Ringer solution attached to the tube provided an initial physiological human intraocular pressure of 1.99 kPa (14.95 mm Hg). 5 Four pressure sensors (Model 113B21, 1379 kPa, PCB Piezotronics) were mounted around the eye. The total sensor, oriented perpendicular to the blast wave front, measured both dynamic and static pressure; the other 3 sensors, oriented parallel to the blast wave front, measured static pressure.…”
