Active clinical trials for "Central Serous Chorioretinopathy"

Laser photocoagulation of the retina targeting the outer layers is an established therapy for proliferative retinopathy and macular edema from diabetic microangiopathy or retinal vein occlusion, centrals serous retinopathy, and extrafoveal subretinal neovascular membranes. However, collateral damage occurs and scotomas can result when using conventional lasers with pulse duration of 100ms and more. This is particularly relevant for laser treatments of the macula where the main therapeutic effect results from stimulation of the retinal pigment epithelium cells and photoreceptor damage is thought to be an unnecessary side effect. Recent experimental research with new laser devices using much shorter pulse duration has shown that photoreceptor damage can be greatly reduced and the retinal pigment epithelium selectively targeted, hence the term selective retinal pigment epithelium laser therapy (SRT). Investigators hypothesize that SRT is equally effective as standard laser photocoagulation for macular disease but minimizes local visual field defects. In this study, patients with central serous retinopathy, macular edema from diabetic microangiopathy or branch vein occlusion, and non-exudative age-related macular degeneration will be treated with SRT. Patients will be assessed 1, 3 and 6 months after treatment.

Objectives: To conduct a Natural History Observation Study to characterize the clinical features and progression of Central Serous Chorioretinopathy (CSCR) from the earliest to the vision-threatening stages. Collect genetic samples of affected individuals and their families to establish whether there is a genetic basis for the disease. To create a Registry of patients affected by CSCR who may agree to be contacted for inclusion in future clinical trials. To determine the incidence and risk factors for progression of pachychoroid phenotypes identified from the unaffected fellow eyes of CSCR patients. Design and subjects: Observation, non-interventional study with prospective follow-up for 2 years. The study aims to enroll 350 patients with CSCR (100 from Hong Kong Eye Hospital, 80 from Prince of Wales Hospital and Alice Ho Miu Ling Nethersole Hospital, and 170 from Chinese University of Hong Kong (CUHK) Eye Centre at Hong Kong Eye Hospital). Study instruments: Functional tests include visual acuity and microperimetry. Retinal imaging with non-invasive ultra-widefield colour fundus camera, fundus autofluorescence (FAF) and optical coherence tomography (OCT). Questionnaires for risk factor profiling and quality of life assessment. Blood specimen will be collected for genetic testing if found to have a clinical diagnosis of CSCR as determined at CUHK Eye Centre at Hong Kong Eye Hospital. Main outcome measures: The primary outcome will be longitudinal alteration of retinal pigment epithelium defects on FAF, spectral domain (SD) OCT and infrared imaging. The secondary outcomes are: 1) progressive attenuation of outer nuclear layer (ONL), external limiting membrane (ELM) and ellipsoid zone (EZ) on SD OCT, 2) longitudinal changes of subfoveal choroidal thickness on swept source (SS) OCT, 3) incidence and onset of intraretinal cysts, 4) incidence and onset of type 1 choroidal neovascularization, 5) rate of choriocapillaris non- perfusion on SS OCT angiography (OCTA), 6) rate of loss of retinal sensitivity using microperimetry tests, 7) rate of visual acuity loss, 8) epidemiology of risk factors associated with CSCR, 9) identification of genes and the genetic variants that are associated with susceptibility to CSCR and 10) documentation of the clinical course of serous retinal detachment recurrence(s), persistence and resolution.

Background: Central serous chorioretinopathy (CSC) is a disease that causes fluid to collect under the retina. It affects the macula, which is in the center of the retina and is needed for sharp, clear vision. In many cases, CSC resolves on its own and does not need treatment. However, in some cases it does not go away or comes back after treatment. This is known as chronic CSC. Chronic CSC may be caused by hormones called androgens. Finasteride is a drug that can alter the effects certain of androgens. Researchers want to compare finasteride with a placebo to see if it is a safe and effective treatment for chronic CSC. Objectives: - To see if finasteride is a safe and effective treatment for chronic CSC. Eligibility: - Individuals at least 18 years of age who have chronic CSC in one or both eyes. Design: Participants will be screened with a physical exam and medical history. A full eye exam will be performed. Blood and urine samples will also be collected. Some participants may have photodynamic therapy (PDT), the standard treatment for CSC. PDT helps to reduce the amount of fluid in the eye. Participants will need to wait for 3 months after PDT before starting the finasteride study. Participants will be separated into two groups. One group will take finasteride 5 mg (formulated into capsules); the other group will take a placebo capsule. All participants will take the capsules for 3 months. After 3 months on the assigned capsule (finasteride or placebo), all participants will have the opportunity to take finasteride for at least another 4 years and 9 months. This phase of the study is optional. Participants will have regular study visits. At each visit, they will have physical exams and eye exams. They will also provide blood and urine samples. During the first 3 months, participants will have 2 study visits. After 3 months, if the participant continues in the optional (or as needed) phase of the protocol, visits will occur at Month 6, Month 12 and every 12 months thereafter. However, additional visits may be needed.

To evaluate the efficacy and safety of 532 nm green subthreshold micropulse laser (GSML) as a treatment for acute central serous chorioretinopathy (CSCR).

Selective retina therapy (SRT) selectively disrupts the retinal pigment epithelium (RPE) with minimal damage to the photoreceptors. Previous studies have shown SRT to be effective for resolving SRF, while causing only minimal collateral damage to the retina and vision.However, most patients included in prior studies had chronic CSC (≥3 months symptom duration) and SRT efficacy on acute CSC is not fully known. The current study evaluated short-term treatment outcomes following SRT with real-time feedback-controlled dosimetry in Korean patients with acute idiopathic CSC.

To test the effect oral eplerenone versus placebo in patients with central serious chorioretinopathy .

The purpose of this study is to determine the safety and efficacy of PDT at 30% verteporfin dose in the treatment of CSC.

The aim of this study was to evaluate safety and therapeutic response to micropulse diode 810nm laser treatment in patients with chronic central serous chorioretinopathy.

The purpose of this study is to evaluate the clinical efficacy of an initial subthreshold retinal micropulselasercoagulation versus a single intravitreal 1.5mg bevacizumab injection in central serous choriretinopathy, as the micropulse will selectively treat the damaged RPE to induce reproliferation of healthy RPE cells, whereas the intravitreal injection should non-selectively stop the RPE leakage.

The purpose of this study is to compare the efficacy and safety of intravitreal ranibizumab injection versus low-fluence PDT in the treatment of chronic CSC.
