OBJECTIVE: To study the results of orbital decompression based on the severity of @entity5768 . DESIGN: A retrospective noncomparative interventional case series. @entity1 : Thirty-nine orbits in 23 @entity1 with thyroid-related orbitopathy at a university-based referral center. INTERVENTION: Graded orbital decompression was performed in all @entity1 based on the severity of preoperative exophthalmometry. MAIN OUTCOME MEASURES: Exophthalmometry, visual acuity, margin-to-reflex distance, prism cover testing, and intraocular pressure. RESULTS: Mean @entity5768 reduction in all orbits was 6.4 +/- 2.7 mm (P < 0.01). In group 1 (preoperative exophthalmometry <22 mm), @entity5768 decreased with a mean of 4.8 +/- 1.3 mm (P < 0.01); mean @entity5768 reduction was 6.0 +/- 2.3 mm (P < 0.01) and 8.9 +/- 3.4 mm (P < 0.01) in group 2 (exophthalmometry between 22-25 mm) and group 3 (exophthalmometry >25 mm), respectively. In four of five eyes with @entity1781 there was an improvement of best-corrected visual acuity of 2 lines or more. Margin-to-reflex distance of the upper and lower lids and intraocular pressure were reduced in all groups. New-onset @entity892 developed in two @entity1 (8.7%); 13 of 15 @entity1 (86.7%) who had @entity892 preoperatively had persistent @entity892 postoperatively. Two @entity1 (13.3%) had relief of @entity892 postoperatively. CONCLUSIONS: Graded orbital decompression based on the severity of preoperative exophthalmometry is useful to determine the type and amount of orbital surgery to be performed.
