Brief Summary
The purpose of this investigation is to better understand the inflammatory process that occurs in uveitis (eye inflammation) through study of eye tissues. Patients with uveitis sometimes develop cataracts (clouding of the lens of the eye) or clouding of the vitreous-the gel-like material behind the lens-that can impair eyesight. Those who require cataract surgery or vitrectomy are eligible for this study. Samples of eye tissue and fluid normally removed during standard surgical procedures for these conditions will be given to researchers instead of discarded, as is usually done. Before surgery, patients will undergo routine preoperative tests, including chest X-ray, electrocardiogram, blood tests and urinalysis. They will also have an eye examination and photographs taken of the retina. Other tests that may be performed include fluorescein angiography to evaluate the blood vessels of the retina; ultrasound to examine the back of the eye; and a gallium scan to evaluate inflammation. Immune cells in the blood and eye tissue will be compared and categorized by disease. The eye fluid will be examined for substances involved in the inflammatory process. These studies may provide information that will lead to improved methods of diagnosis and treatment.
