Summary
This study details a Japanese patient with traumatic optic neuropathy (TON). Quantitative Goldmann visual fields (GVFs) helped assess recovery after steroid pulse therapy and optic canal decompression surgery.
Area of Science:
- Ophthalmology
- Neuroscience
- Trauma Surgery
Background:
- Unilateral traumatic optic neuropathy (TON) presents a significant challenge in visual recovery.
- Assessing functional recovery in TON requires sensitive and quantitative methods.
Observation:
- A 70-year-old Japanese male experienced TON in his left eye after a fall.
- Initial visual acuity was 0.2, with orbital wall fracture but no clear optic canal fracture.
- Treatment involved steroid pulse therapy followed by optic canal decompression surgery.
Findings:
- Steroid therapy showed minimal visual acuity improvement and reduced Goldmann visual fields (GVFs).
- Optic canal decompression led to significant visual acuity improvement (0.2 to 0.6) and expanded GVFs.
- Six months post-surgery, visual acuity reached 0.8, though GVFs remained subnormal.
Implications:
- Quantitative assessment of GVFs provides valuable insights into TON recovery dynamics.
- This case highlights the potential efficacy of combined steroid therapy and surgical decompression for TON.
- Developing quantitative GVF indices can aid in evaluating treatment effectiveness for optic nerve disorders.
