View clinical trials related to Central Serous Chorioretinopathy.
Filter by:Central serous chorioretinopathy (CSC) is a common eye disease mainly involving the macular area, causing central visual acuity loss. Recently, subthreshold micropulse laser used in treating chronic CSC is proved to be safe and effective. However, some studies indicate that it's less effective than half dose photodynamic therapy (PDT). Certain physicians, including us, think that this may be related to micropulse laser parameters. Thus we need to explore better laser patterns to replace PDT in treating chronic CSC. The aim of this study is to compare the treatment effect of two different patterns of laser parameters (small and regular spot diameter) in treating chronic CSC. In this randomized, double blinded, controlled trial, by comparing the subretinal fluid regression ratio, central retinal thickness, macular microvisual field, macular vascular density, chroidal volume changes and visual acuity of two groups 6 months after micropulse laser treatment, we aim to evaluate the safety and efficacy of refined micropulse laser in treating chronic CSC.
Deep learning allows you to classify images using a self-learning algorithm. Transfer learning builds on an existing self-learning algorithm to enable image classification with fewer images. In this study, this technique will be applied to different image modalities in different syndromes. Retrospective study design.

Acute central serous chorioretinopathy (CSC) is a common disorder in middle-aged patients, characterized by serous retinal detachment in the macular region. We evaluated half-dose verteporfin photodynamic therapy (hd-PDT) versus 689 nm laser treatment in chronic CSC. Twenty-two eyes of 22 patients with symptomatic chronic CSC were randomized in a 1:1 ratio to receive hd-PDT (group 1) or 689-LT delivering 95 J/cm2 by application of an intensity of 805 mW/cm2 over 118 seconds. Best-corrected visual acuity (BCVA) and spectral-domain optical coherence tomography findings were compared between groups.
Central serous chorioretinopathy (CSC) is supposedly the fourth most common non-surgical retinopathy after age-related macular degeneration, diabetic retinopathy and branch retinal vein occlusion. The disease was first described by Albrecht von Graefe in 1866 as a 'recurrent central retinitis' and is nowadays commonly known as 'central serous chorioretinopathy', a term mainly coined by Donald Gass in the late 1960s. Although the disease has been known for decades, the underlying mechanism is not yet fully understood. Numerous studies have shown an involvement of the retinal pigment epithelium (RPE) and the choroid which lead to accumulation of subretinal fluid with subsequent detachment of the neurosensory retina. Among several assumed risk factors, high serum glucocorticoid levels seem to be related to the occurrence of CSC. CSC typically affects young, male patients unilaterally and causes decreased and distorted vision, often associated with metamorphopsia, micropsia, dyschromatopsia and reduced contrast sensitivity. CSC can occur in an acute or chronic form. However, there is no agreement in the literature concerning the duration of the two forms. Some authors define CSC as chronic if there is persistent subretinal fluid for at least 6 months 11, others speak of chronic CSC when symptoms last longer than 3 months. In contrast there are studies where CSC is defined acute within the first 4 months. Spontaneously absorption is possible in up to 50% and normally leads to the recurrence of a normal visual acuity. Chronic CSC can result in a wide spread RPE damage and in a constantly reduction of visual acuity. Structural changes in the retina and RPE have been found about 2 months after onset of the disease. Those changes can cause accumulation of photoreceptor outer segments, lead to consecutive atrophy of the photoreceptor cells and are associated with a loss of visual acuity. Different concepts of treatment exist, but none of these may be deemed to be the golden standard. In the past few years several studies where CSC was treated with photodynamic therapy (PDT) or half-fluence PDT showed good visual outcomes and morphologic reconstitution. However, PDT is a destructive method which causes structural damage and can trigger other severe complications like choroidal ischemia and iatrogenic CNV. Furthermore, CSC is a self-limiting disease in many cases and physicians often hesitate to perform a relatively destructive therapeutical approach to treat a potentially self-limiting disease. A newer, non-destructive therpeutical concept is the oral use of eplerenone a mineralocorticoid receptor antagonist. It is currently used in the treatment of hypertension and congestive heart failure. In the recent literature it was shown that eplerenone improved CSC and no serious adverse effects were observed in any case. However, no randomised controlled studies were performed comparing eplerenone with placebo to evaluate the clinical effect.
Central serous chorioretinopathy (CSC) is a disease of unknown origin however multiple reports have indicated correlation of appearance of CSC with exposure to exogenous or elevated levels of endogenous corticosteroid. Since the level of endogenous corticosteroids is upregulated in many inflammatory conditions, control of the inflammation may be beneficial in reducing this level thus eliminating the stimulus for CSC. Methotrexate (MTX) is widely used to control different types of inflammation. The investigators are going to try an escalating doses of MTX to treat CSC under full medical supervision.
