Summary
A novel surgical technique combining subciliary anterior orbitotomy and endoscopic medial wall resection effectively treats compressive optic neuropathy from thyroid-related orbitopathy, improving vision with low morbidity.
Area of Science:
- Ophthalmology
- Neurosurgery
- Endocrinology
Background:
- Compressive optic neuropathy is a rare but serious complication of thyroid-related orbitopathy.
- Surgical orbital decompression is necessary to relieve apical crowding and restore vision.
- Existing surgical methods have varying degrees of efficacy and morbidity.
Observation:
- A combined surgical approach using subciliary anterior orbitotomy and endoscopic medial wall resection was developed.
- This technique allows extensive decompression of the orbital apex, medial wall, and orbital floor.
- The infraorbital nerve canal is preserved, and the anterior orbital floor supports the globe.
Findings:
- The combined approach achieved significant decompression of the orbital apex.
- Two patients experienced dramatic improvement in visual function after the surgery.
- The procedure demonstrated low morbidity, similar to endoscopic techniques.
Implications:
- This surgical refinement offers technical advantages for treating thyroid-related compressive optic neuropathy.
- The combined approach provides an effective option for vision restoration in complex cases.
- Further studies may validate this technique as a standard of care.
