Central serous retinopathy, or CSR, is 10 times more common in men between 20 and 50 than in women. Up to 50% of people with CSR in both eyes are found to be taking some form of steroids. Initially, CSR forms below the retina. An accumulation of clear fluid builds up between the retina and the choroid. Eventually, it penetrates the retina causing it to separate over the macula area. Diagnosis is usually confirmed by fluorescein angiography. In this test, your retinal specialist is able to see a special dye accumulate at the location of the CSR. Other tests, such as OCT, may also help in detecting the separation of the retina. Symptoms of CSR include: blurred vision; distorted vision, where objects appear smaller, and faded vision, where objects appear 'washed out'. 90% of people with CSR don't require any treatment as it resolves within 6 months.
