Clinical Trial: Tissue Studies of Human Eye Diseases

This study is currently recruiting patients.

Sponsored by: National Eye Institute (NEI)
Information provided by: Warren G Magnuson Clinical Center (CC)


The purpose of this study is to better understand the processes involved in the development of various eye conditions, such as uveitis, disorders of the conjunctiva, cornea, vitreous and retina, metabolic or genetic eye diseases or eye tumors, in order to develop better methods of diagnosis and treatment.

Patients who require eye surgery to treat an eye disease or other disease in which the eye is involved may participate in this study. Samples of eye tissue and fluid that are normally removed and discarded during eye surgery will instead be given to researchers for study. The tissues will be examined under microscope and studied using sophisticated chemical and biological tests. Immune cells from blood samples may also be examined. These studies will help better understand and diagnose the various eye diseases and to develop more attractive therapies.

Expected Total Enrollment:  3000

Study start: March 5, 1992

The purpose of this project is to diagnose and evaluate ocular tissues with various diseases such as uveitis, conjunctival, corneal, vitreoretinal disorders, ocular metabolic or genetic diseases and tumors. These will be studied using light microscopy, electron microscopy, confocal microscopy, immunohistochemical techniques, in situ hybridization and the molecular pathological techniques including polymerase chain reaction. Lymphocyte subsets in the peripheral blood as well as other involved biopsied tissues and ocular tissue will be compared and categorized by disease. Cytokines in the blood and ocular fluids will be also analyzed. Elucidating the relationship between the infiltrating cells, ocular resident cells, and their products in various diseases will increase our understanding of human ocular disorders.


Genders Eligible for Study:  Both


All specimens either male or female of any age with ocular disease that are collected at the NEI or its collaborating institutes, will be included in the study. Specimens would consist of material obtained from surgical specimens, biopsy specimens, and from post mortem materials. These would include but would not be limited to cases involving uveal, conjunctival, corneal, vitreo-retinal, orbital disorders, tumor, and metabolic abnormalities.
