Importance: The timing and indications for repair of @entity8924 have been controversial. Current practice dictates that @entity174 involving more than 50% of the orbital floor should be repaired. Early management is initiated in such situations to prevent long-term sequelae of @entity9577 and @entity892 . Because @entity174 size as measured by computed tomography (CT) is one of the criteria to determine the need for surgical repair, there is a need to know the reliability of this parameter. Objective: To assess the variability of CT measurements of @entity8924 . Design, Setting, and @entity1 : This study took place between January 1, 2005, and June 1, 2007, at an urban academic medical center. @entity1 with isolated @entity8924 were evaluated by 1 oculoplastic surgeon, and their orbital CT images were subsequently read by 3 neuroradiologists blinded to demographic information and the other readers' measurements. Separately, each was asked to determine the maximal anterior to posterior length and transverse width if a floor @entity174 existed. Main Outcomes and Measures: Intraclass correlation coefficients were calculated for length and width using a 2-way mixed-effects model to evaluate the agreement between radiologists. Results: Twenty-three @entity1 met criteria for inclusion in this study ( @entity8924 thought to be in need of repair, with @entity892 within 30   of primary gaze, and/or @entity9577 >2 mm, and/or 50% of the floor area involved in the @entity174 ). The mean (SD) age of the @entity1 was 31.5 (17.6) years (range, 8-73 years). The magnitude of agreement between the readers as measured by the intraclass correlation coefficient was 0.66 (95% CI, 0.46-0.82) for anterior to posterior length and 0.44 (95% CI, 0.22-0.69) for transverse width, indicating only a moderate degree of concordance. Conclusions and Relevance: Although the literature has long held that a floor @entity174 seen radiographically to involve 50% of the orbital floor has a high likelihood of enopthalmia and should be repaired, this study shows how variable CT measurements of @entity8924 can be in a clinical setting, even in trained hands. We question the @entity734 on such a criterion and reemphasize the importance of making surgical decisions based on clinical findings rather than radiological interpretations.
