Central Serous Chorioretinopathy Central serous chorioretinopathy, commonly referred to as CSC, is a condition in which fluid accumulates under the retina, causing a serous (fluid-filled) detachment and vision loss. CSC most often occurs in young and middle-aged adults. For unknown reasons, men develop this condition more commonly than women. Vision loss is usually temporary but sometimes can become chronic or recur.
The causes of CSC are not fully understood. It is thought that any systemic exposure to a corticosteroid drug can bring about or worsen CSC. Corticosteroids are found in allergy nose sprays and anti-inflammatory skin creams available over the counter, and are often prescribed to treat a variety of medical conditions.
Blurry central vision, which often occurs in one eye, is the most common symptom that patients experience; however, careful examination often reveals some involvement in the other eye as well.
