Summary
This study shows that a combined endoscopic and transconjunctival orbital decompression effectively treats thyroid-related orbitopathy, improving vision and reducing proptosis with few complications.
Area of Science:
- Ophthalmology
- Endoscopic Surgery
- Thyroid Eye Disease
Background:
- Thyroid-related orbitopathy (TRO) can cause orbital apex compression, leading to vision loss.
- Surgical decompression is necessary for severe cases, but optimal approaches are debated.
Purpose of the Study:
- To evaluate the efficacy and safety of a combined endoscopic and transconjunctival orbital decompression for TRO with orbital apex compression.
- To assess the impact on visual acuity, proptosis, and diplopia.
Main Methods:
- Retrospective review of 41 patients undergoing 72 combined decompressions between 1992 and 2001.
- Preoperative and postoperative evaluations included visual acuity, exophthalmometry, and diplopia assessment.
- Complications and need for secondary procedures were recorded.
Main Results:
- Visual acuity improved in 89.3% of patients with optic neuropathy and 34.1% without.
- Average proptosis reduction was 3.65 mm.
- Complications were minimal, including transient CSF extravasation and epistaxis.
Conclusions:
- Combined endoscopic and transconjunctival decompression is a safe and effective treatment for thyroid-related orbital apex compression.
- The approach offers rapid visual recovery, reduced proptosis, and short hospital stays.
- Visual improvements were sustained and significant, particularly in patients with optic neuropathy.
