Summary
Surgical orbital decompression effectively reduces proptosis in Graves' orbitopathy patients. Both antral-ethmoidal and transconjunctival methods offer safe and beneficial outcomes for vision and eye muscle function.
Area of Science:
- Ophthalmology
- Endocrinology
- Surgical Science
Background:
- Graves' orbitopathy (GO) is an autoimmune condition causing orbital inflammation and tissue expansion.
- Proptosis, diplopia, and optic neuropathy are common GO manifestations requiring intervention.
- Surgical decompression is considered after medical management failure.
Purpose of the Study:
- To review the authors' experience with surgical decompression for Graves' orbitopathy.
- To evaluate the safety and efficacy of different surgical approaches.
Main Methods:
- Retrospective study of 126 consecutive primary orbital decompressions.
- Tertiary care university hospital setting.
- Antral-ethmoidal or transconjunctival decompression techniques were employed.
Main Results:
- Mean proptosis reduction: 5.3 mm (antral-ethmoidal) and 3.6 mm (transconjunctival).
- Visual acuity improved in 34 orbits; ocular motility improved or remained stable in 21 of 30 patients.
- Complications were infrequent, indicating a favorable safety profile.
Conclusions:
- Antral-ethmoidal and transconjunctival orbital decompression are safe and effective treatments for Graves' orbitopathy.
- These surgical interventions can significantly improve proptosis and preserve or enhance visual function and ocular motility.
