Active clinical trials for "Uveitis"

The usefulness of diagnostic vitrectomy in patients with suspected sarcoidosis with posterior segment involvement (in whom a diagnosis cannot be determined by conventional methods) has not been well described. We hypothesized that diagnostic vitrectomy would help establish the diagnosis in these challenging cases. Herein, we evaluated the diagnostic yield of vitreous biopsy in patients with suspected sarcoidosis-associated uveitis that affected the posterior segment.This is a retrospective interventional case series. Cases of intermediate, posterior or panuveitis that could not be characterized by clinical examination, ancillary, and laboratory tests were considered for diagnostic pars plana vitrectomy. Retrospective chart review was conducted on consecutive eyes that underwent diagnostic, or diagnostic and therapeutic vitrectomy by a single surgeon from January 1989 to June 2006.

Pediatric uveitis accounts for 5-10% of uveitis cases. it may be infectious or noninfectious in etiology. The etiology of noninfectious uveitis may be autoimmune. The most common causes of pediatric uveitis are idiopathic and juvenile idiopathic arthritis-associated uveitis. Uveitis morbidities in pediatric patients include cataract, glaucoma, and amblyopia. Pediatric uveitis may be accopanied by involvement of the ocular vasculature, such as retinal vasculitis. We hypothesize that there are differences in systemic microcirculation between pediatric uveitis patients and healthy pediatric controls.

Optical Coherence Tomography (OCT) is routinely used in ophthalmic clinical practice. It uses infrared light to image patient's eyes. Some patients, such as those with an inflammatory disease called uveitis or those who have just undergone cataract surgery, have intraocular inflammation. This intraocular inflammation commonly manifests as cells that can be seen on routine microscopic clinical examination. However, the only currently available method to quantify this intraocular inflammation is by manually counting on the microscopic clinical examination. The investigators plan to use the OCT machine to image patient's eyes. The investigators will then use the images obtained from the OCT to objectively quantify the degree of intraocular inflammation.

The Chinese Spondyloarthritis Inception cohort (CESPIC) was started 2000 as a prospective, longitudinal, multicentre, nationwide study in China on patients with early SpA including ankylosing spondylitis (AS, also known as radiographic axial spondyloarthritis) and non-radiographic axial SpA. The objectives of CESPIC are to learn about the course of SpA during the very early stage of the disease, to appropriately assess the outcome including radiographic progression of patients after several years of follow-up, to identify outcome predictors, to assess quality of life, function, and costs (direct and indirect costs). CESPIC has been recently expanded to recruit patients with other forms of SpA / conditions associated with SpA: reactive arthritis, acute anterior uveitis, Crohn's disease as well as with psoriasis / axial psoriatic arthritis.

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.

The primary objective of this study is to demonstrate equivalence of the pharmacokinetic (PK) profile of MSB11022 administered by either an auto-injector (AI) or a pre-filled syringe (PFS) as single subcutaneous (s.c.) injection of 40 mg.

The purpose of this study is to determine if a medical device (ActiPatch) that emits a low frequency pulsed electromagnetic field (PEMF) will benefit patients with anterior uveitis. Anterior uveitis (aka iritis) is an inflammatory disease involving the front segment of the eye. This is a common cause of a painful red eye, and ActiPatch has been shown to be effective in treating tissue inflammation. The conventional treatment of iritis typically involves frequent administration of topical steroids which have their own inherent risks (development of cataracts and/or glaucoma). The purpose of this study is to determine if ActiPatch therapy can be used to shorten the length of time and/or quantity of steroids administered.

The purpose of this study is to determine the safety and efficacy of difluprednate compared with prednisolone acetate in the treatment of endogenous anterior uveitis.

Retinal optical coherence tomography (OCT) is an established technology which enables a detailed cross-sectional visualization of the retinal micro-anatomy, and an objective measurement of its thickness in-vivo. Multifocal electroretinogram (MfERG) measures function of the central retina. Both technologies are relatively new and they provide complimentary to each other information on retinal anatomy and function. The aims of this study is to establish normal ranges for OCT and mfERG measurements related to age, gender and reproductive factors such as parity and the use of contraception in Norwegians; to assess the presumably healthy central retina with the use of anti-inflammatory medication with relation to age and sex ; to study the frequency and extent of retinal thickening and change in retinal function in patients with anterior uveitis not complicated with macular edema; to assess whether the presence of the HLA-B27 haplotype or uveitis recidive affects macular thickening/function in uveitis.

The trial will compare the effect on disease control and immunosuppression treatment of adding simvastatin 80mg once daily, over a follow-up and treatment period of 2 years. Patients will be randomised in a 1:1 fashion to standard treatment with placebo or standard treatment with the addition of simvastatin (80mg daily). They will be followed at 3 months intervals for 2 years with a primary end point of mean reduction in corticosteroid dosage at the 12 month follow-up visit.
