The purpose of this study was to measure the changes in intraocular pressure (IOP) and refraction following orbital decompression for thyroid orbitopathy.
Methods:Retrospective review of 18 eyes in 10 consecutive patients who underwent orbital decompression including intraconal fat excision for proptosis secondary to thyroid orbitopathy. IOP using tonopen, exophthalmometry, autorefraction and autokeratometry measurements were performed at 1-week, 1-month and 3-months after surgery.
Results:There was no statistically significant difference between the preoperative and postoperative IOP at 3 months. There were no significant differences found between preoperative and post operative keratometry readings or automated refraction following orbital decompression.
Conclusion:Our study did not find a significant change in IOP and refraction following orbital decompression with intraconal fat excision. A larger prospective study is required in order to evaluate the role of intraconal fat excision in reducing IOP due to it’s potential role in patients with concurrent glaucoma
