| sclerite | A hard plate or spicule which may be composed of chitin or calcium carbonate, often refers to the rigid parts of the arthropod (insects, crustaceans, etc.) exoskeleton. (09 Oct 1997) |
| scleritis | 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 characterised 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. Aetiology 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. (12 Dec 1998) |
