PURPOSE: To address the efficacy of fat-removal orbital decompression to reduce intraocular pressure in patients with Graves disease. METHODS: This cohort study included 64 eyes of 39 patients with Graves disease. Thirteen men and 36 women, with a mean age of 52.5 years (range, 27 to 80 years), underwent fat-removal orbital decompression. Intraocular pressure (applanation) and proptosis (Hertel exophthalmometry) were prospectively investigated before surgery and 1 week and 6 months after surgery. RESULTS: The volume of resected fat was 6.4 ± 4.5 (3 to 12) ml. The intraocular pressure in primary position decreased from 19.3 ± 4.4 mmHg to 17.0 ± 2.9 mmHg at 1 week (p < 0.001) and 15.9 ± 3.7 mmHg at 6 months (p < 0.001). Mean proptosis dropped from 24.3± 2.5 mm before surgery to 19.9±3.0 mm at 1 week (p < 0.01), and 19.9 ±3.1 mm at 6 months (p < 0.01). Intraocular pressure decrease neither correlated to the volume of resected fat nor to proptosis reduction. CONCLUSIONS: Fat removal reduces intraocular pressure in patients with Graves disease, with no correlation to the volume of resected fat.
