Centralis serous chorioretinitis (CRCS) is a disease of the retina. In this process, fluid flows from the blood vessels below the retina into the layer of photoreceptors. As a result, these are cut off from the supply of nutrients and oxygen and can therefore no longer function properly.
Vision is usually blurred and distorted in the center. Iridescent colored spots or rings outside the visual center are also typically detected.
One in 10^000 people suffer from CRCS, typically affecting men between the ages of 30-50 who are exposed to increased levels of stress.
When RCS occurs for the first time, the prognosis is very good, i.e. there is usually spontaneous healing without treatment and vision recovers. Permanent or recurring CRCS can result in permanent retinal damage associated with a decline in vision.
If it occurs for the first time or is acute, it makes sense to wait, because in around 70% of cases there is a cure within 4 months or 85% within half a year.
In the case of a chronic course, fluorescence angiography can help to find the point of origin of the fluid discharge. If it is not too close to the visual center, it can be sealed with an argon laser treatment.
During photodynamic therapy (PDT), the retinal vessels are irradiated and thus sealed.
