E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Acute central serous chorioretinopathy (CSC)
CSC is an acute idiopathic chorioretinopathy. While the majority of cases is characterized by a self-limited course, chronic CSC is seen in up to one third of patients. Case reports and first results of small case series have recently been published about the use of intravitreal bevacizumab with promising results. It is not known if Lucentis (Ranibizumab) may yield same or better results in CSC and prove superior to observation alone. |
|
E.1.1.1 | Medical condition in easily understood language |
CSC leads to fluid accumulation below the central parts of the retina, the so called macula. This leads to a decrease in vision.
It affects people between 30 and 50 years of age, predominantly men. |

|
|
E.2.2 | Secondary objectives of the trial |
Secondary endpoint is the change of best spectacle-corrected visual acuity as measured by ETDRS vison charts at baseline and six months after inclusion into the study |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Patient age >18 a, <60 a

Symptom duration less than three months
|
|
E.4 | Principal exclusion criteria |

Recurrent CSC
St.p. intraocular surgery within the past year
St.p. Argon laser coagulation of the retina

|
E.5.2 | Secondary end point(s) |
