Active clinical trials for "Central Serous Chorioretinopathy"

Central serous choroidal (CSC) retinopathy is a disease of the macula characterized by exudation of fluid under the retina localized to the posterior pole as well as loss of vision. The etiology is unknown, but according to the studies this condition is more common in young males and is associated with type A personality. Clinically, CSC is characterized by serous retinal detachment and area of leakage of in the subretinal space. The standard of care for acute CSC is observation for a period of up to 3 months. If there is no complete resolution of the retinal detachment by 3 months, there is an indication for focal laser photocoagulation therapy of the area of leakage. This treatment is usually effective in stopping leakage of fluid under the retina and causing resolution of detachment. However, laser photocoagulation therapy is not beneficial in the treatment of chronic CSC because there is not a single easily identifiable point of leakage but rather diffuse disease of RPE thus rendering laser treatment ineffective.The purpose of this medical research study is to evaluate Verteporfin therapy as an approach which may benefit patients with CSC, based on observations in exudative type of AMD patients treated with Photodynamic Therapy using Verteporfin.

Purpose: To investigate the efficacy of combined use of retinal repetitive electromagnetic stimulation and subtenon autologous platelet-rich plasma in the treatment of recalcitrant or unresponsive chronic central serous chorioretinopathy.

The goal of the study is to assess the efficacy and safety of mifepristone 300 or 900-mg once-daily dosing by mouth for 4 weeks in patients with central serous chorioretinopathy.

A preliminary study to determine the safety and efficacy of intravitreal aflibercept injection in patients with persistent central serous chorioretinopathy.

The purpose of this study is to determine the effect of an adrenocorticoid antagonist (ketoconazole), 600 mg per day for 4 weeks, in the treatment of patients with central serous chorioretinopathy (CSC).

The aim of the study is to determine the efficacy and safety of treatment with the drug eplerenone in patients with chronic central serous chorioretinopathy.

Chronic central serous chorioretinopathy (CSC) is a relatively frequent eye disease that often occurs in patients in the professionally active age range. In this disease, there is pooling of fluid under the central retina (the macula). This specific form of macular degeneration can cause permanent vision loss, image distortion, loss of color and contrast vision due to this fluid under the retina. An early diagnosis and treatment may improve the visual outcome and quality of life. To date there is no international consensus on the optimal treatment of chronic CSC. Many retrospective studies suggest that treatment with photodynamic therapy (PDT) is effective in chronic CSC. Micropulse laser (ML) therapy may also be effective in this disease. The proposed study is the first prospective randomized controlled trial in chronic CSC. In this study, participants with chronic CSC will be randomized into two treatment groups, PDT or ML treatment. The trial is a superiority study, because retrospective studies suggest that PDT treatment may be more effective than ML treatment. Therefore, PDT treatment is challenged against ML treatment. The null hypothesis of the study is that PDT treatment is more effective than ML treatment in patients with active chronic CSC. The alternative hypothesis is that PDT treatment is not more effective than ML treatment in these patients. Treatment success will not only be based on anatomical improvement, but also on functional endpoints, which are most important from a patient's perspective. The study will take place in five large tertiary referral university hospitals in Europe that have extensive experience with conducting clinical trials (in Nijmegen, the Netherlands; Cologne, Germany; Leiden, the Netherlands; Oxford, United Kingdom; and Paris, France). Each of these centers has confirmed sufficient funding to conduct the research. The study will last max. 8 months per participant. Each participant will come for 5 (in the case of 1 treatment) or 7 visits (in the case of 2 treatments). Study evaluations will be mostly part of regular clinical care. The whole study will last for max. 24 months.

Central serous chorioretinopathy (CSC) is a self-limiting disease that usually associated with good visual prognosis. In some cases, however, CSC may persist and result in permanent retinal or retinal pigment epithelium (RPE) damage. Therefore, if the disease is persistent beyond the acute phase, an active treatment should be considered to prevent an irreversible damage to retinal function. The pathophysiology of CSC is associated with abnormal choroidal circulation. Indocyanine green angiography (ICGA) has revealed dilated and congested choroidal vessel and leakage into the extracellular space that appears as area of hyperfluorescence seen in middle and late phase in eyes with CSC. A goal of treatment has been focused on reducing choroidal hyperpermeability. Currently, photodynamic therapy with verteporfin (PDT) and intravitreal anti-VEGF (vascular endothelial growth factor)antibody injection are being tried in order to treat chronic CSC. PDT reduces choroidal hyperpermeability by inducing hypoperfusion of the choriocapillaris in the short term and choroidal vascular remodeling over time. Intravitreal anti-VEGF injection for the treatment of CSC also effectively reduces choroidal hyperpermeability by blocking vascular leakage. Both methods have shown to be effective with good functional outcome for treating chronic CSC in many reports, but until now there is no established standard treatment protocol for chronic CSC. Bevacizumab (Avastin) and ranibizumab (Lucentis) have been used widely as anti-VEGF therapeutic agent for the treatment of age related macular generation (AMD) and macular edema of various reasons. A newly developed anti-VEGF drug, aflibercept (Eylea○R), shows higher affinity to VEGF and has a longer duration of effect in the vitreous.FDA approved aflibercept to treat wet type AMD and macular edema due to central retinal vein occlusion. Until now, no study has been reported on the efficacy and safety of aflibercept for treating CSC. The aim of this study is to evaluate the efficacy and safety of intravitreal aflibercept injection for the treatment of idiopathic CSC

OCTA-guided PDT is as safe and effective as ICGA-guided PDT in the treatment of acute central serous chorioretinopathy. Or OCTA-guided PDT is more effective than ICGA-guided PDT in the treatment of acute central serous chorioretinopathy, safe as well.

The purpose of this study is to observe whether micropulse laser (MPL) is noninferiority to traditional laser therapy in central serous chorioretinopathy.
