Obwohl das primäre Antigen nach wie vor ungewiss ist, dürfte der im Orbitagewebe exprimierte TSH-Rezeptor – möglicherweise durch „molekulares Mimikry” mit bakteriellen oder viralen Epitopen – eine wesentliche Rolle spielen. Nach Toleranzverlust gegenüber dem endogenen TSH-Rezeptor kommt eine T-Zell-abhängige immunologische Entzündungsreaktion in Gang, die über Zytokine, Interleukine und Prostaglandine zu einer Akkumulation von hydrophilen Glykosaminoglykanen (v. a. Hyaluronsäure, Chondroitinsulfat) im orbitalen Binde-, Fett- und Muskelgewebe führt. Neuen Befunden zufolge spielt auch die gesteigerte Rekrutierung, Differenzierung und Ausreifung von orbitalen Präadipozyten zu Adipozyten und die damit einhergehende Expression des TSH-Rezeptors eine wichtige Rolle. Folge hiervon ist eine aus­geprägte Volumenzunahme der orbitalen Gewebe mit zunehmender räumlicher Enge in den knöchern begrenzten Orbitae. Durch den intraorbitalen Druckanstieg kommt es als natürliche Form der Druckentlastung zur Protrusio bulbi bei gleichzeitiger Lidretraktion und zu einem schwellungsbedingten Prolaps der entzündlich veränderten Binde- und Fettgewebsanteile in die Ober- und Unterlider (periorbitale Ödeme). Zusätzlich können Motilitätsstörungen der äußeren Augenmuskeln auftreten, die je nach Ausmaß der asymmetrischen Beeinträchtigung mit Doppelbildern einhergehen. Mit steigender Raumnot entwickeln sich intraorbital zunehmend mechanische Komplikationen, die durch venöse Kongestion, Gewebehypoxie und Bildung von freien Sauerstoffradikalen (Rauchen!) noch verschlimmert werden. Im Extremfall kann die massive Volumenzunahme der Orbita­gewebe zur Expositionskeratitis und Optikusneuropathie führen, die neben den kosmetischen Problemen zu den gravierenden Komplikationen der endokrinen Orbitopathie zählen.</p><p>Interactions of Fibroblasts, Adipocytes and Immunocompetent Cells in the Pathogenesis of Graves’ Ophthalmopathy</p><p><b>Summary:</b> Graves’ ophthalmopathy is thought to result from a complex interplay of genetic and environmental factors.

Cardiovascular-related diseases are the leading cause of death among these patients and responsible for almost half of all deaths in dialysis patients.
