Active clinical trials for "Chorioretinitis"

Fungal Chorioretinitis is a vision threatening condition.The investigators evaluate the efficacy of SD-OCT role in the treatment

The purpose of this study is twofold: To analyze the clinical features of a cohort of patients with birdshot chorioretinopathy (BCR), an inflammatory bilateral ocular disease, affecting the choroid and the retina. Various imaging techniques will be used to assess the effect of the disease on the retina and the choroid. A standardized assessment of the visual function will be performed with visual acuity, visual field and color vision testing. The quality of life of the patients will be evaluated with the VFQ-25 questionnaire. These analyses will help delineating different forms of the disease among its heterogeneous presentations. To identify predisposing factors for the disease. The condition is unique from the immunogenetic standpoint by its association with the HLA-A29 allele, which is the strongest link between an HLA class I antigen and a disease. To date, however, the mechanisms leading to birdshot chorioretinopathy remain unknown. GWAS (Genome Wide association Study) based on DNA of the cohort patients will be performed with the aim to identify other susceptibility genes associated with BCR.

Vitiligo patients on systemic and local therapy may have some ocular adverse effects associated with the disease and its therapy.

The objective of the study is to evaluate the effect of spironolactone on 16 patients presenting with chronic non-resolutive central serous chorioretinitis (CSCR) and to evaluate whether spironolactone can resolve sub retinal fluid in these patients. CSCR is a major cause of visual loss in the young population. It is characterized by sub retinal fluid under the retina and retinal pigment epithelial detachments. The exact causes of the disease remain unknown but a choroidopathy has been suggested. Moreover, corticotherapy and stress are known risk factors of CSCR. Our preclinical studies have demonstrated that the mineralocorticoid pathway could be involved in the control of choroidal blood flow. The investigators propose to evaluate the mineralocorticoid receptors antagonist spironolactone in the treatment of CSCR. Criteria of efficacy Endpoint: reduction of subretinal fluid ≥ 40 microns Secondary endpoint: visual acuity gain ≥ 15 EDTRS letters

Toxoplasmosis, an intra cellular parasite, is a very important cause of chorioretinitis. The goal of treatment is arresting multiplication of the parasite in its inflammatory active phase. In this study the investigators try to compare the efficacy of the classic regimen (Pyrimethamine-Sulfadiazine + Prednisolon) with intravitreal Clindamycin & Dexamethasone.

The purpose of this study is to determine the effectiveness of antiangiogenic therapy to choroidal neovascularization secondary to central chorioretinitis.

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.

This is a search strategy for determining the prevalence of ocular complications in inflammatory rheumatic diseases for the purposes of a meta analysis.

The aim of this study is to investigate short and long term consequences from early postnatal HCMV infection transmitted via human milk in very preterm infants (birth weight < 1500 g or gestational age < 32 weeks). These infants are at high risk of early death or survival with chronic disease and neurodevelopmental impairment if infected with HCMV. Infection is a common complication in this group of patients and reported to be the most frequent cause of death after the second week of life. Systemic infection in the newborn period is reported as representing an independent risk factor for survival with neurodevelopmental impairment among very preterm infants.
