A patient presenting with scleritis should be considered for underlying systemic conditions, as scleritis is frequently associated with systemic autoimmune or inflammatory diseases . Approximately half of all scleritis cases are linked to an underlying systemic disease .

  • Rheumatoid arthritis is a common systemic condition associated with scleritis .
  • Other connective tissue diseases such as Systemic Lupus Erythematosus (SLE) should be considered .
  • Vasculitides are important to investigate, particularly Granulomatosis with Polyangiitis (formerly Wegener's granulomatosis), which can cause severe ocular and systemic disease . Other vasculitides like Polyarteritis Nodosa may also be linked .
  • Spondyloarthropathies, such as ankylosing spondylitis and psoriatic arthritis, are also associated with inflammatory eye conditions .
  • Other conditions that may be considered include inflammatory bowel disease (Crohn's disease, ulcerative colitis) and sarcoidosis .
  • Raynaud's phenomenon, while a symptom, can be indicative of underlying connective tissue diseases that are associated with scleritis .
