TRAUMATIC OPTIC NEUROPATHY – CASE REPORT WITH DISCUSSION ON DIAGNOSTIC PROCEDURES AND THERAPY

Traumatic optic neuropathy (TON) is a serious vision threatening condition that can be caused by ocular or head trauma. Indirect damage to 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 signifi cant 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 fi ngers at 2 meters’ on the right eye due to keratoconus and ‘counting fi ngers at 1 meter’ on the left eye as a consequence of trauma. Th e Octopus visual fi eld showed diff use reduction in retinal sensitivity and the Ishihara color test indicated dysfunction of color perception on the left eye. Relative aff erent pupillary defect was also present. Computed tomography revealed multifragmentary fracture of the frontal sinus and the roof of the left orbit without bone displacement. Based on the fi ndings, conservative corticosteroid therapy without surgery was conducted. Th e patient responded well to treatment with complete ophthalmologic recovery.
