Scleritis affects people between the ages of 30 and 60 years old, and is very uncommon in children. Slightly occurs more frequently in women. Affects a population of more than 200,000 people, but less than 1 million.
Scleritis is an inflammation of the sclera, which is the white outer wall of the eye. It is present within the entirety (depth) of the sclera. An eye and/or physical examination with blood tests are used to diagnose this disease. There are four types: › Diffuse anterior: The most common form. Presents with widespread inflammation of the anterior sclera. Accounts for 50% of scleritis cases. › Nodular: There are erythematous (red), tender, fixed nodules, which, in 25% of cases progresses to necrotising scleritis. Commonly reccurs. › Necrotising: 10% of cases- characterized by extreme pain and marked scleral damage. Associated with underlying systemic disease (See:Why?) › Scleromalacia perforans: 5% of cases. Known as necrotising without inflammation . Notable for lack of symptoms.
Blurred vision Sensitivity to light (can be painful) Eye pain and tenderness Tearing of the eye Fever Vomiting Headaches Red patches on the white part of eyeball › Normal cases are mild redness to this area › Severe cases are extreme redness to this area
Normally associated with auto-immune diseases such as: › Rheumatoid arthritis › Systemic lupus erythematosus › Sometimes the cause is unknown
If not treated, significant loss of vision can occur. Normally treated with oral anti- inflammatory medications, corticosteroids, and sometimes immunosuppressive drugs, depending on the evidence of an underlying systemic disease. Doesn’t normally respond to topical eye drop medications. Being based upon certain incurable auto- immune diseases, many cases cannot be cured, but managed.
