Immune Responses to Antigens in Non-infectious Eye Inflammatory Diseases

July 25, 2018 updated by: National Eye Institute (NEI)

Evaluation of Immune Responses to Different Antigens in Non Infectious Ocular Inflammatory Diseases

This study will collect blood samples from patients with non-infectious eye inflammatory diseases a spectrum of eye disorders that can produce sight-threatening vision loss. The blood will be analyzed for substances that may provide a better understanding of the nature of these disorders, possibly leading to improved treatments. Treatment is not offered under this protocol.

Patients 6 years of age and older with an eye inflammatory disease, including non-infectious uveitis, ocular cicatricial pemphigoid, non-infectious scleritis, episcleritis, Stevens Johnson syndrome, Moorens ulcer, peripheral ulcerative keratitis and keratoconjunctivitis sicca, may be eligible for this study. Patients may or may not currently be participating in a treatment trial.

Participants will have blood drawn through a needle in an arm vein. More samples may be collected if patients enrolled in another study are scheduled for additional visits. No more than 4 teaspoonfuls of blood will be collected at any one time.

Conditions

Detailed Description

Ocular inflammatory diseases can lead to visual loss in adults as well as in children. These conditions are usually characterized by repeated exacerbations and remissions. The underlying cause of majority of these conditions is not clear even though an autoimmune mechanism has been implicated. Various studies have reported an altered immunological profile in these patients. An underlying immune mechanism has been thought to be playing a role in at least some of the ocular inflammatory diseases. In addition, evidence from literature also suggests inflammatory disease may be an important mechanism leading to Age related macular degeneration and Diabetic retinopathy, two leading causes for vision loss. However, very little is known about the involvement of immune components in these patients.

This protocol proposes to test for proliferative cell mediated and humoral responses against self-antigens from patients with ocular inflammatory diseases, AMD and diabetic retinopathy. Patients will be recruited from other ongoing protocols. An attempt would be made to find any correlation between the clinical disease and the immunological findings. These findings will not be used for diagnostic nor therapeutic purposes.
