View clinical trials related to Uveitis.
Filter by:Background: Uveitis is inflammation inside of the eye. It can cause vision loss. Little is known about the disease. There are few treatment options. Researchers want to learn how the bacteria in the gut might affect how people with uveitis respond to treatment. Objective: To investigate the natural bacteria present in the gut and intestines to study whether it might affect uveitis treatment. Eligibility: People ages 13 and older with non-infectious uveitis who are enrolled in the ADalimumab Vs. conventional ImmunoSupprEssion for uveitis (ADVISE) trial, and their uveitis is being treated or will be treated with an oral corticosteroid, conventional immunosuppressive drugs, or adalimumab. Design: Participants will have 2 study visits at their respective clinical sites. The visits will be 6 months apart. The visits will align with the main ADVISE trial visits. Participants will give blood samples. A needle will be used to take blood from an arm vein. They will also give stool samples. They will get stool collection kits. They will collect each sample at home and send it to the NIH. Participants will complete online diet history questionnaires. They will get an ID and password to access the questionnaires. The ID is a unique code. This means it does not contain any personal identifiers. They can complete the questionnaires at home. Participation in this study will last for 6 months.
Objective: To determine the clinical variables that influence aqueous outflow facility (Co) and intraocular pressure (IOP) in uveitis. Uveitic glaucoma is potentially blinding and occurs in 17-46% of chronic uveitis patients. Uveitic activity causes fluctuating IOP due to decreased Co, increased uveoscleral outflow or decreased aqueous production. Specific Aim 1: To evaluate the risk factors for high IOP and low Co in uveitis Hypothesis: Decreased Co and increased IOP will occur with increasing anterior chamber (AC) flare, AC cells, degree of synechial angle closure, increased duration of disease, higher uveitis activity and increasing steroid use Specific Aim 2: To determine prospectively the effect of AC flare on Co and IOP in "quiescent" uveitis Hypothesis: AC flare even in the absence of AC cells will cause progressive decline in Co. Methods: In this proof of concept study, thirty consecutive patients with acute or chronic uveitis will be recruited from the uveitis clinic. Ten patients with "quiescent" uveitis (no AC cells) will be recruited for the prospective arm and followed every 2-3 months for 3 visits. Co will be measured using 2-minute pneumatonometer tonography. The effect of risk factors on IOP and Co in uveitis will be studied using generalized linear modelling techniques. These risk factors include AC flare (using the laser flare meter), AC cells, degree of angle closure (by gonioscopy), duration of disease, disease activity and corticosteroid use within the last year. In the prospective study, the patients will be divided into subgroups with low flare (< 20ph/ms) and high flare (≥ 20 ph/msec) and the change in Co and IOP will be analyzed. Impact: This will be the first study to systematically analyze the risk factors for decrease in Co and increase in IOP in uveitis and to prospectively evaluate the effect of AC flare on Co. Proof that AC flare can damage the trabecular meshwork will corroborate previous experimental evidence and change the paradigm of uveitis treatment. Knowledge of the risk factors that affect Co and IOP will aid in identifying patients that may need escalation of their uveitis or glaucoma treatment to prevent optic nerve damage.
Macular edema is the most common sight threatening complication of uveitis which can lead to permanent loss of central vision. Triamcinolone acetonide ( the study drug)injection for treatment of cystoid macular edema(CME) is well established. The purpose of this study is to compare the safety and efficacy of injecting the study drug inside the eye(intravitreal injection) and behind the eye(subtenon injection)
This study is aimed at creation and validation of a vitreous haze scoring system using ultrasonography B-scan of the eye. Images will be obtained from patients with uveitis and quantification of inflammation will be done to create the scoring scale.
This is a Phase 2, randomized, double-masked, placebo-controlled study subjects with active, sight-threatening, noninfectious intermediate or posterior uveitis.
This study will assess the safety, tolerability, and efficacy of FTY720 in patients with acute, noninfectious intermediate, posterior and pan uveitis
Background: - Uveitis is an eye inflammation that can cause vision loss. It is treated with eye drops, drugs and sometimes surgery. In some people, treatment may not prevent vision loss. A type of white blood cells called T-cells often have a role in causing uveitis. In some cases of uveitis, T-cells attack the eye and cause inflammation. A drug called ustekinumab reduces inflammation from these T-cells. Researchers want to see if ustekinumab can be used to treat uveitis. Objectives: - To see if ustekinumab can be used to treat uveitis. Eligibility: - Individuals at least 18 years of age who have active uveitis that needs treatment. Design: - Participants will be screened with a physical exam, eye exam, and medical history. Blood and urine samples will be taken. - Participants will have at least eight clinic visits during the 64-week study period. After the first visit, visits will occur at 2, 4, and 8 weeks, and then every 12 weeks. - Participants will have a ustekinumab injection at the first study visit. They will have additional doses at the second and third visits, and then every 12 weeks until 1 year after the first dose (Week 52). - Treatment will be monitored with frequent blood tests and eye exams. Other standard treatments for uveitis may be given as needed. - There will be a final study visit 3 months after the last injection.
This study will provide patients who have completed the AIN457 Phase II and Phase III clinical trials in non-infectious uveitis continued access to treatment with AIN457 while collecting safety data and information on long term clinical use of treatment with AIN457.
The purpose of this study is to find out about the safety and effectiveness of two different doses the study drug, sirolimus, administered intravitreally in patients with uveitis. The potential effectiveness of sirolimus can be utilized to control inflammation in uveitis and yet avoid the potential complications that are usually associated with the systemic use of the drug and other immunomodulatory therapies. In this study, the investigators will administer sirolimus inside the eye (intravitreally) in one of two doses (440mcg/mcL or 880mcg/mcL). 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.
The purpose of the extension study was to provide patients completing the 28-week core study (NCT01095250) with an opportunity to receive an additional 22 weeks of continuous treatment.
