Retrobulbar hemorrhage is a rare complication that may occur after mid-face injuries or following soft and hard tissue surgery around the eyes. The cardinal signs and symptoms of retrobulbar hemorrhage are pain, diplopia, ophthalmoplegia, a progression of increasing proptosis, and decreasing visual acuity leading to blindness. The diagnosis can be confirmed with computed tomography (CT) of the orbit or with ocular ultrasound. These diagnostic images are also important to define the size of the hematoma. This report describes a traumatic retrobulbar hemorrhage. In this case there were no signs of acute visual loss, and conservative treatment was possible without surgical intervention.
