Summary
Microsurgical decompression improved vision in 82% of traumatic optic nerve injury patients. Early intervention (under 14 days) with preoperative visual acuity of 0.01 or more yielded the best outcomes.
Area of Science:
- Neurosurgery
- Ophthalmology
- Trauma Surgery
Background:
- Traumatic optic nerve injury (TONI) can lead to significant vision loss.
- Surgical decompression aims to alleviate pressure on the optic nerve.
Purpose of the Study:
- To evaluate the efficacy of transfrontal intradural microsurgical decompression for TONI.
- To identify predictors of successful surgical outcomes.
Main Methods:
- Microsurgical decompression via a transfrontal intradural approach was performed on 22 patients.
- Visual acuity was assessed preoperatively and postoperatively.
- Outcomes were analyzed based on preoperative visual acuity and time to surgery.
Main Results:
- 50% of patients achieved significant visual acuity improvement (≥0.1).
- 80% of patients with preoperative visual acuity ≥0.01 showed significant improvement.
- 38% of patients with preoperative visual acuity <0.01 showed significant improvement.
Conclusions:
- Transfrontal intradural microsurgical decompression is a viable treatment for TONI.
- Optimal candidates have preoperative visual acuity ≥0.01 and undergo surgery within 14 days.
- Patients with preoperative blindness did not experience improvement.
