thinning of the sclera in a patient with recurrent scleritis. Note: the patient also has trabeculectomy.
This condition is seen mainly in women with rheumatoid arthritis. The eye may be tender and you need to elevate the lid gently.
There is exposure of the underlying dark uveal tissue (usually covered by the upper lid) with thinning of the surrounding sclera. The uvea is covered by thin connective tissue and conjunctiva. There are large abnormal blood vessels crossing areas of scleral loss.
This condition is caused by necrotizing scleritis without inflammation and is seen in patients with long-standing rheumatoid arthritis.
