Sažetak
Traumatic optic neuropathy (TON) is a serious vision threatening condition that can be caused by ocular or head trauma. Indirect damage of the optic nerve is the most common form of TON occurring in 0.5% to 5% of all closed head trauma cases. Although the degree of visual loss after indirect TON may vary, approximately 50% of all patients are left with "light perception" or" no light perception" vision, making TON a significant cause of permanent vision loss. We present a 47-year old male patient with a history of right eye keratoconus following a motorcycle crash. Visual acuity was of "counting fingers at 2 meters" on the right eye due to keratoconus and "counting fingers on 1 meter" on the left eye as a consequence of trauma. The Octopus visual field showed diffuse reduction in retinal sensitivity and the Ishihara colour test indicated dysfunction of colour perception on the left eye. Relative afferent pupillary defect on the left eye also was present. Computed tomography revealed multifragmental fracture of the frontal sinus and the roof of the left orbit without bone displacement. Based upon the findings conservative corticosteroid therapy without surgery was conducted. The patient responded well to treatment with complete ophthalmological recovery.
