Secondary Effects of Orbital Decompression in Thyroid Eye Disease: A Review.

PURPOSE

Orbital decompression is mainly performed in thyroid eye disease to reduce proptosis and retrobulbar pressure, to improve venous congestion, and to relieve optic nerve compression. Secondary effects of orbital decompression are also occasionally encountered. The aim of this study was to review the secondary effects of orbital decompression.

METHODS

This is a comprehensive literature review that summarizes the secondary effects of orbital decompression.

RESULTS

Decreased intraocular pressure, inter-pupillary distance, and eyelid pressure, and improvement of eyelid retraction, lateral flare, orbital discomfort, and psychosocial condition after orbital decompression are favorable changes for patients. In contrast, refractive changes in some patients and decreased Bell's phenomenon and nasal function worsen patients' condition.

CONCLUSION

These favorable changes may reduce the patients' burden for treatment of thyroid eye disease. In contrast, as some of the adverse effects significantly worsen the patients' disease condition, we should carefully monitor these changes.
