CSR, also known as central serous chorioretinopathy (CSC), is a visual impairment, often temporary, usually in one eye, mostly affecting males in the age group 20 to 50 but which may also affect women. The disorder is characterized by leakage of fluid in the central macula usually with a "blister" appearance (Fig 1), which results in blurred or distorted vision (metamorphopsia). A blind or gray spot in the central vision is common, along with flashes of light (photopsia).
