Filter by:The purpose of this study is to find out about the safety and effectiveness of the study drug, sirolimus, in patients with uveitis and to utilize the potential effectiveness of sirolimus, and yet to avoid the potential complications of systemic use of the drug. In this study, the investigators will administer sirolimus either around (subconjunctival injection) or inside the eye (intravitreal injection). Local administration of sirolimus to the eye is not expected to have effects on the rest of the body. Therefore, it may offer a safer way than the current methods used to control the inflammation caused by non-infectious uveitis.
Background: - Uveitis is an inflammatory condition in which the patient's own immune system attacks the eye, causing eye inflammation and vision loss. Patients with uveitis may be treated with immunosuppressive medications to reduce the inflammation and prevent vision loss. - Sirolimus is an immunosuppressive medication that is approved by the U.S. Food and Drug Administration (FDA) to prevent organ rejection following a kidney transplant. Researchers think that sirolimus may affect the part of the immune system that may be an important cause of uveitis, and may decrease the inflammation that causes uveitis. - In this study, sirolimus will be given as an injection under the outer layer of your eye. The FDA has permitted the investigational use of sirolimus for this study. Objectives: - To determine if subconjunctival injection of sirolimus is safe for treatment of uveitis. - To see if sirolimus is an effective treatment for uveitis. Eligibility: - Patients 18 years of age and older with active uveitis in one or both eyes. If a patient has uveitis in both eyes, the one in which the inflammation is worse will be treated during the study. The vision in the study eye must be at least 20/400. - Patients must have good liver function, and must be willing to practice sun protection measures for 2 weeks following the treatment. Design: - Treatment with sirolimus in the study eye: - Antibiotic and numbing eye drops will be given before the sirolimus injection. - 1 dose of sirolimus will be injected directly into the subconjunctiva (white part of the eye). - Antibiotic drops will be given for topical application 3 times per day for 2 days after the injection. - Patients will be followed for 16 weeks after sirolimus injection (initial visit and follow-up visits in Weeks 2, 4, 8, 12, and 16). - Evaluations during the treatment period and follow-up visits: - Physical examination, including vital signs and body weight checks, and pregnancy test for women who can become pregnant. - Full medical and ophthalmic history, involving questionnaires and discussion with researchers. - Eye examination, dilation, and photography, including measurements of retinal thickness and fluorescent dye tests of blood flow in the eye. - Blood and urine tests. - Because of the increased risk of skin cancer associated with sirolimus, patients ...
Uveitis is a group of troublesome diseases that collectively represent a cause of blindness comparable to diabetes. Most forms of uveitis are either infectious or immune-mediated. The investigators propose to create a data base on peripheral blood gene expression for patients with 3 of the most important diseases associated with uveitis: ankylosing spondylitis, sarcoidosis, and Behcet's disease. The investigators will quantitatively measure the expression of consistent alteration in peripheral blood from patients with more than 40,000 gene sequences using microarray gene chip technology. This approach is known to detect systemic immune-mediated disease. The investigators will use this data base to: 1. Determine if patients with uveitis and ankylosing spondylitis, sarcoidosis, or Behcet's can be distinguished from a normal population or controls with the same systemic disease but no history of uveitis 2. Determine if the profile of gene expression can distinguish infectious or idiopathic forms of uveitis from patients with spondylitis, sarcoidosis, or Behcet's 3. Determine how this gene profile changes over time as episodic disease such as spondylitis or Behcet's activates or remits 4. Correlate the changes in gene expression with the prognosis of the ocular inflammatory process. The creation of a gene expression data base for patients with uveitis has the potential to clarify the pathogenesis of disease, establish new diagnostic tools, and provide a means for predicting prognosis.
Environmental factors possibly influencing uveitis are evaluated.
The purpose of this study is to determine whether ESBA105, a topically applied TNF-alpha inhibitor, is safe and clinically active when applied to the eye of patients suffering from acute anterior uveitis
Study efficacy of everolimus on course of uveitis: - obtain quiescence of inflammation after start of treatment - duration to obtain quiescence of inflammation - number of patients with quiescence of inflammation
In uveitic patients with fluorescein angiographically proven macular edema, a fundus related microperimetry is performed and results are correlated with foveal thickness as measured with optical coherence tomography (OCT).
According to a recent estimate more than 280,000 people in the United States are affected by uveitis each year. This report, also estimated that uveitis is the reason for 30,000 new cases of blindness/year and up to 10 percent of all cases of blindness. The purpose of this trial is to determine the effectiveness of VEGF blockade with intravitreal pegaptanib in patients with uveitic CME.
The purpose of this study is to determine whether some endothelium morphologic variables are different between infectious and noninfectious uveitis group using a noncontact specular microscopy device.
The purpose of this study is to define a safe and effective dose of iontophoretic delivery of dexamethasone phosphate ophthalmic solution using the EyeGate® II Drug Delivery System in patients with non-infectious anterior segment uveitis.
