BACKGROUND: A case of unilateral @entity1781 secondary to @entity11283 following a medial orbital wall fracture is presented. CASE REPORT: A 41-yr-old U.S. Air Force aviator presented for a routine periodic health assessment. Evaluation uncovered a suspected acquired color @entity735 ( @entity5771 ). Subsequent discussions with the @entity1 revealed a history of @entity3856 , redness, and proptosis during a flight overseas several years earlier. Local ocular examination demonstrated asymmetric optic nerve cupping, optic nerve pallor @entity5771 , a mild asymmetric color deficit, and a significant @entity227 . Evaluation with magnetic resonance imaging revealed findings consistent with an old medial orbital wall fracture @entity5771 and optic nerve findings consistent with @entity1781 . Follow-up evaluation by neurology and otorhinolaryngology demonstrated only extensive sinus pathology. Based upon these findings, it is postulated that the member suffered a medial orbital wall fracture at altitude during ascent caused by expanding ethmoid sinus gases due to abnormal sinus anatomy with subsequent right @entity18489 leading to an @entity1781 and subsequent visual sequelae. DISCUSSION: This case demonstrates one possible @entity66 while working in the aerospace environment. Several case reports have been published demonstrating the potential link between @entity4858 and working in an environment with fluctuating atmospheric pressure. However, literature addressing the specific in-flight environment causing such complications is lacking. Furthermore, the case supports the need for versatility and a broad knowledge base in practicing flight surgeons to evaluate ocular pathology. Powell MR, Hurley LD, Richardson TC.
