Abstract
PURPOSE: The purpose of this study was to compare the histopathologic inflammation and fibrosis of orbital adipose tissue in orbital inflammatory disease (OID) specimens.
METHODS: In this retrospective cohort study, inflammation, and fibrosis in orbital adipose tissue from patients with thyroid-associated orbitopathy (TAO), granulomatosis with polyangiitis (GPA), sarcoidosis, nonspecific orbital inflammation (NSOI), and healthy controls were scored by 2 masked ocular pathologists. Both categories were scored on a scale of 0 to 3 with scoring criteria based on the percentage of specimens containing inflammation or fibrosis, respectively. Tissue specimens were collected from oculoplastic surgeons at 8 international centers representing 4 countries. Seventy-four specimens were included: 25 with TAO, 6 with orbital GPA, 7 with orbital sarcoidosis, 24 with NSOI, and 12 healthy controls.
RESULTS: The mean inflammation and fibrosis scores for healthy controls were 0.0 and 1.1, respectively. Orbital inflammatory disease groups' inflammation (I) and fibrosis (F) scores, formatted [I, F] with respective p -values when compared to controls, were: TAO [0.2, 1.4] ( p = 1, 1), GPA [1.9, 2.6] ( p = 0.003, 0.009), sarcoidosis [2.4, 1.9] ( p = 0.001, 0.023), and NSOI [1.3, 1.8] ( p ≤ 0.001, 0.018). Sarcoidosis had the highest mean inflammation score. The pairwise analysis demonstrated that sarcoidosis had a significantly higher mean inflammation score than NSOI ( p = 0.036) and TAO ( p < 0.0001), but no difference when compared to GPA. GPA had the highest mean fibrosis score, with pairwise analysis demonstrating a significantly higher mean fibrosis score than TAO ( p = 0.048).
CONCLUSIONS: Mean inflammation and fibrosis scores in TAO orbital adipose tissue samples did not differ from healthy controls. In contrast, the more "intense" inflammatory diseases such as GPA, sarcoidosis, and NSOI did demonstrate higher histopathologic inflammation and fibrosis. This has implications in prognosis, therapeutic selection, and response monitoring in orbital inflammatory disease.
