Introduction
An open globe laceration is defined as a full-thickness penetration of the eye by a sharp object.[1] Observational studies suggest that male patients ages 10-19 are at highest risk for this type of injury due to types of sports they participate in, occupations, and involvement in physical altercations.[2,3] Obvious signs of trauma are not always apparent, and a negative Seidel’s test does not rule out an occult intraocular foreign body as the wound may temporarily seal itself if small enough.[4] Decreased visual acuity, chemosis, hypotony, and pain are often the only clues that the patient has an open globe injury.[5] Early diagnosis and evaluation by an ophthalmologist are crucial to preserving vision.[6] In this case report we present an atypical case of a 24-year-old male patient with penetrating eye trauma to his right eye that was not apparent on physical exam or computed tomography.
