Abstract
PURPOSE: To report a case of corneal edema associated with Descemet membrane (DM) damage likely due to shockwave trauma from a bullet passing by the eye. OBSERVATIONS: A 27-year-old man presented to the emergency department with pain, redness, and severely decreased vision in the left eye immediately following a gun assault. Examination of the eye revealed a temporal conjunctival laceration, corneal edema, hyphema, and vitreous hemorrhage. Bullets were found in the patient's left chest and axilla, and a laceration was present on the bridge of his nose, but no foreign bodies were found in or around the eyes. The intraocular hemorrhage and corneal edema gradually resolved, and it became apparent that there were DM irregularities that possibly represented micro-ruptures. After 7 months, uncorrected visual acuity improved to 20/25, and the cornea was free of edema but had persistent small focal areas of DM thickening and scarring. CONCLUSIONS AND IMPORTANCE: This case illustrates that DM and possibly endothelial cell damage can occur due to shockwave injury from high-speed projectiles. In our case of presumed small central DM micro-ruptures, the corneal edema resolved, and the vision significantly improved with topical therapy and observation, suggesting an overall good prognosis from such injuries.
