      1. Rheumatoid Arthritis (most common cause)

    4. Scleral edema
    5. Corneal Ulceration
    6. Scleromalacia (severe cases)
      1. Sclera thins and takes on a bluish hue
  7. Signs: Slit Lamp Exam
    1. Critical to do this exam prior to Fluorescein application
      1. Fluorescein can settle in the stroma and obscure the Scleritis findings and extent
    2. Localized, raised hyperemia of Sclera
    3. Elevated Scleral vessels
    4. Scleritis does not blanch with topical Phenylephrine
      1. Phenylephrine blurs vision for 3 hours

Scleritis (C0036416)

Definition (MSH) Refers to any inflammation of the sclera including episcleritis, a benign condition affecting only the episclera, which is generally short-lived and easily treated. Classic scleritis, on the other hand, affects deeper tissue and is characterized by higher rates of visual acuity loss and even mortality, particularly in necrotizing form. Its characteristic symptom is severe and general head pain. Scleritis has also been associated with systemic collagen disease. Etiology is unknown but is thought to involve a local immune response. Treatment is difficult and includes administration of anti-inflammatory and immunosuppressive agents such as corticosteroids. Inflammation of the sclera may also be secondary to inflammation of adjacent tissues, such as the conjunctiva.
