Filter by:Thyroid Associated Ophthalmopathy is condition affecting the eyes of about 10% of patients with Graves disease. Its combination of protrusion affecting the looks of the patient and pain is often severely affecting the quality of life among these patients. The standard treatment for this illness today is intravenous glucocorticoids together with methotrexate. The purpose of this study is to evaluate the effect of rituximab on patients that do not respond to or relapse after conventional therapy.
The purpose of this study is to evaluate the efficacy of LME636 compared to vehicle in the reduction of ocular symptoms and to evaluate the safety and tolerability of LME636, when administered topically for up to 42 days, in subjects with severe dry eye disease.
Anti-VEGF agents are given for a variety of previously untreatable eye diseases. The last years indications for their use and consequently the number of patients needing treatment, have been increasing. Most patients require multiple injections. This has resulted in many eye departments administering thousands of injections per year, also at St Olavs University Hospital Trondheim. To cope with this increase in workload, it would be helpful if injections would be given not only by the physicians but also by the nurses. This study's objective is to compare efficiency, patient satisfaction and cost per patient of injections given by nurses and physicians.
The purpose of this study is to evaluate the safety and efficacy of X-82 in the treatment of vision loss due to wet AMD.
Thyroid eye disease is an autoimmune disorder affecting approximately 50% of individuals with autoimmune thyroid diseases resulting in enlargement of ocular muscles and may lead to congestion of the eyelids and ocular surface, ocular movement restriction and double vision, and optic nerve compression and loss of vision. First line medical therapy is oral or intravenous corticosteroids (CS), which several studies have shown results in reduction of soft tissue congestion, but some studies suggesting that ocular restriction or visual loss may still occur in spite of CS therapy.i External beam radiotherapy (XRT) is second line therapy but is controversial, with some studies suggesting benefit in preventing onset of double vision or optic nerve compression while other studies suggest it has no benefit. Most proponents of XRT for TED believe that it is most effective early in the disease evolution. XRT has been shown to be a safe therapy with few side-effects, although retinopathy changes have developed in a small percentage of diabetics and its use is avoided for diabetics. Combined oral prednisone and XRT has been shown to be more effective in reducing soft tissue inflammation and motility complications than either monotherapy in two different studies. To date there have been no trials comparing combined XRT and iv CS with iv CS alone for early progressive TED to identify potential benefit in reducing the severity of motility disorders or preventing the onset of dysthyroid optic neuropathy. That is the purpose of this study.
Dry age-related macular degeneration (AMD) is a common cause for severe visual loss in the elderly and represents an unmet need. So far no treatment is available for geographic atrophy (GA), which represents the advanced dry form characterized by expanding areas of outer retinal atrophy with corresponding absolute scotoma. The foveal retina may be spared until late in the course of the disease, a phenomenon termed "foveal sparing". However, the disease process ultimately also involves the central retina leading to irreversible loss of central vision. While the natural history of eyes with GA has been extensively studied with regard to the entire atrophic area, morphology-function analyses for "foveal sparing" GA in particular are still missing. Such data are needed for various purposes including the future use in interventional pharmacological trials aiming to slow the progression of GA and to preserve the foveal retina. In this study, different imaging modalities for accurate detection and quantification of preserved foveal retinal areas will be assessed.
Choroidal thickness represents blood-flowing of eyes. The investigators detect the choroidal thickness of the young participant using SD-OCT to see the effect of Resveratrol Based Nutritional Supplement on Choroidal Thickness.
There is blood-eye barrier in eyes,but some oral medicines can enter in the tissues of eyes. The primary objective of the study is to study the Pharmacokinetics of Trans-resveratrol and Its three Metabolites in Human Eyes and Blood
Background: - By the time diseases of the retina are detected, serious damage has often already been done. Researchers want to find better ways of viewing the retina. One way called adaptive optics may help detect problems earlier. Objectives: - To study if adaptive optics can help find better ways to diagnose, treat, and manage retinal diseases. Eligibility: - People over age 12 with an eye disease. - Healthy volunteers over age 12. Design: - Participants will be screened with medical history and eye exams. These may include dilating pupils and taking pictures of the eyes. - Participants will have 1 or more study visits. They will have: - Medical and eye history. - Questions about their medications. - Eye exam including pupil dilation. - Adaptive optics imaging. After dilation, participants sit still while looking into an adaptive optics instrument. They look at specific places and images are taken of their retina. - They may also have: - More images. - Perimetry. Participants look into a lens and press a button when they see a light. - Color vision tests. - Electroretinogram. Participants will get numbing eye drops and special contact lenses. A small metal electrode will be put on their forehead. They will look at flashing lights and try not to blink.
Thyroid eye disease (TED) is an autoimmune inflammation of the orbital tissues that develops in up to 50% of patients with Graves' disease. Although about 80% respond to IVGC initially, the relapse rate is high and about 75% require further surgery despite initial response. Although the natural history of TED is associated with spontaneous remissions after about 1 to 3 years, many irreversible serious ophthalmic and orbital complications can arise during this time. Therefore, there is a need for improved intervention strategies in the early active inflammatory phase of TED, to avoid progression to the cicatricial stage where disease manifestations can only be addressed in a rehabilitative fashion. The primary immunopathogenesis of Graves' disease is considered to be activation of B cells that then produce autoantibody against thyrotropin receptors in the thyroid (TRAb). Like in many autoimmune diseases, the inflammatory CD4+ T cell subset known as Th17 cells is also increased in blood of patients with active Graves' disease; the putative Th17 cytokine, IL-17, is also increased in serum and tears of TED patients. There is also an emerging pathogenic role for Th17 cells that co-express the chemokine receptor CXCR5 and drive autoantibody production. The contribution of Th17 cells to TED is not well defined. This study is an observational, longitudinal, prospective study of patients receiving treatment for thyroid eye disease.
