BACKGROUND: Indirect Traumatic optic neuropathy (ITON) is a severe disease characterized by a sudden decline of visual function after craniofacial injury. However, the best treatment for ITON is unknown. Endoscopic transnasal optic canal decompression (ETOCD) has gradually been used for ITON treatment worldwide in recent years.
OBJECTIVE: To assess the effect of ETOCD on visual acuity in patients with ITON and identify factors that affect prognosis.
METHODS: In this study, clinical characteristics of 44 ITON patients who underwent ETOCD in Qilu Hospital of Shandong University were retrospectively analyzed. Factors affecting prognosis were also evaluated.
RESULTS: ETOCD treatment improved the vision of 20 (45.5%) patients with no patient suffering from vision deterioration. The mean value of visual acuity (VA) scores improved from 1.57 to 2.39 (P < 0.001). Patients with residual vision had a better VA improvement percent than those without light perception (66.67% versus 34.48%, χ2 = 4.13, P = 0.042). Although shorter duration before ETOCD was associated with better improvement score in ITON patients (r = -0.30, P = 0.044), optic canal fracture (OCF) and optic nerve sheath incision did not affect the prognosis of these patients. Five ITON patients with cerebrospinal fluid rhinorrhea were treated with free nasal mucosal flap during the surgery, and no other severe surgical complication occurred.
CONCLUSIONS: ETOCD can effectively and safely improve the vision of ITON patients, patients with residual vision and those treated earlier may benefit more from this surgery.
