Active clinical trials for "Uveitis"

The investigators hypothesize that it is safe and effective to treat patients with choroidal neovascularisation (abnormal blood vessels growing under the retina) secondary to uveitis with Conbercept. This will be a randomized, placebo-controlled trial. 20 patients will receive three injections of Conbercept into the affected eye (and repeated injections if required), and 20 patients will receive three sham injections requiring no needle stick, but making the patient unaware of whether or not he received active treatment. Outcome of the two treatment groups will be compared after one year.

In the STOP-UVEITIS study, we propose to evaluate the safety, tolerability, and bioactivity of two doses of Tocilizumab (4mg/kg and 8mg/kg), administered monthly, in patients with non-infectious intermediate, posterior, or panuveitis.

To evaluate therapeutic interventions for patients who have choroidal melanoma, the most common primary eye cancer affecting adults, and to assess the potential life-preserving as well as sight-preserving role of radiation therapy. To determine which of two standard treatments, removal of the eye or brachytherapy, is more likely to prolong survival of eligible patients with medium-sized choroidal melanoma. To determine whether preoperative radiation prolongs life for patients whose eyes with large choroidal melanoma are enucleated.

Toxoplasmosis affects one to two newborn each 10000 births. Among them, 1 to 2 % develop learning disabilities or die, and 4 to 27 % develop a chorioretinitis sometimes leading to an amblyopia responsible for visual impairment. Toxoplasmosis uveitis affects too adults immunocompetent and immunodepressed who have had an acquired toxoplasmosis. Clinical diagnosis of ocular toxoplasmosis is more complicated in presence of posterior neuro-retinitis, inflammation of the papilla, uveitis without chorioretinitis, fuchs heterochromic iridocyclitis, scleritis, diffuse necrotizing or multifocal retinitis. In this situation biological markers diagnostic and prognostic of toxoplasmosis uveitis are useful. Highly kept molecules (during evolution) like stress proteins (Hsp) are are found in the host and the pathogen and there can trigger a crossed immune response. Stress proteins haven't been explored yet, in the context of toxoplasmosis uveitis on humans. The hypothesis is that Hsp70 and antibodies anti-Hsp70 are diagnostic and prognostic markers of ocular toxoplasmosis. The goal is to evaluate diagnosis value of biological markers (Hsp70 and antibodies IgG anti-Hsp70) in toxoplasmosis uveitis.

The purpose of this study is to compare flaremetry readings with the protein content of the aqueous humor and the clinical grading of flare.

Cystoids macular edema (CME) is one of the most common causes of low vision due to uveitis. The treatment for reducing the intra-ocular inflammation can decrease the macular edema. In some patients, CME persists even after inflammation control, and additional treatment is needed for better vision. Oral steroid, periocular and intravitreal Triamcinolone are the principles in treatment, but some complications like cataracts and increased ocular pressure have been seen. Diclophenac is a non-steroid anti-inflammatory drug that improves the vision and decreases the macular thickness by slowing down the prostaglandin E2 (PGE2) ending in vascular endothelial growth factor (VEGF) inhibition. In this study, the investigators are going to compare the therapeutic affect of intravitreal Diclophenac and Triamcinolone in persistent uveitic cystoids macular edema. Since diclophenac is a cheap and accessible drug in all curative centers it could be applied instead of Triamcinolone.

Our research project is to use a new microbiological diagnostic strategy of uveitis, allowing detection of the fastidious pathogens of infectious Uveitis who are not diagnosed by laboratory methods used in diagnostic routine. This new diagnostic strategy is to automatically detect the presence of a pathogen fastidious in cell culture using the same patient's serum to reveal a positive culture, based on the assumption that this serum contains antibodies specific pathogen tedious. Finally, the main purpose of this study is to improve the etiological diagnosis of Uveitis by establishing a new diagnostic strategy.

The Uveitis, the inflammation of the uvea, is a rare disease with an incidence of 52/100,000 inhabitants per year and a prevalence of 115 / 100,000 inhabitants per year. The causes of uveitis are numerous and include infectious diseases, systemic and neurological diseases, ophthalmic entities, neoplasia, and drug-related reactions. The etiological diagnosis is important both for prognosis and therapeutics. However, clinical evaluations to establish etiological diagnosis are not standardized. Some authors suggest a minimalist examination, common to all kinds of uveitis. On the other hand, others propose an evaluation guided by the anatomo-clinical type of uveitis. We conducted a retrospective study to assess the contribution of complementary examinations to etiological determination. In this study, we found that most patients benefited from a wide paraclinical evaluation compared to what is usually described in the literature. Complementary examinations were mostly systematic, without any clinical or ophthalmological elements of orientation. This study highlighted the lack of contribution of some examinations. Using these results, and the literature analysis, we designed a diagnostic algorithm adapted to the anatomo-clinical type of uveitis. Moreover, we found that the average cost per patient was estimated at €290.51 with the algorithm compared to €560.83 without it. We would like to carry out a new study to estimate the efficiency as well as the medico-economic impact of the use of a standardized strategy for the etiological diagnosis of uveitis, compared with a free strategy. Hypothesis: The standardized strategy for the diagnostic of uveitis is at least as efficient as the free one, and costs half as much. The examinations prescribed, except for those from the standardized strategy, do not contribute to etiological determination.

This study evaluates the significance of differences in serum angiotensin converting enzyme and lysozyme levels of patients with ocular involvement of other autoimmune inflammatory and infectious diseases.

This study is a non-interventional, observational extension of the Parent study, CLS1001-301 (NCT02595398). The purpose of this study is to characterize the continued clinical benefit(s) regarding safety and efficacy of suprachoroidally administered CLS-TA, triamcinolone acetonide injectable suspension, for the treatment of macular edema associated with non-infectious uveitis.
