Central Serous Chorioretinopathy (CSCR)
Central
serous
chorioretinopathy (CSCR) is a problem that affects the macula (central
portion of the retina). The exact cause is not understood. CSCR occurs
when a small break forms in the pigment layer of the retina. Fluid from
the layer of blood vessels that lie underneath the retina seeps up
through the break, causing a small detachment to form under the retina.
This problem is somewhat similar to a water blister that forms
on the skin. The process is similar to CSCR: fluid collects beneath the
skin's surface, causing the layers of skin to separate.
CSCR
affects men more often then women and usually occurs between the ages of
25 and 50. Stress is thought to be linked to this problem. CSCR
typically resolves spontaneously, but it can recur. In some cases, it
may lead to moderate but permanent loss of central vision.
SIGNS
AND SYMPTOMS
•Blurred central vision
•Wavy, distorted vision
•Central blind spot
DETECTION AND DIAGNOSIS
Usually the doctor can
diagnose CSCR with an exam of the retina using ophthalmoscopy. In most
cases fluorescein angiography is used to gather additional information
about the extent and severity of the problem.
TREATMENT
Most patients with CSCR do not require treatment. The fluid usually
absorbs gradually over a period of months. Occasionally, steroid and
non-steroidal anti-inflammatory eye drops are prescribed. In cases where
visual recovery is delayed, laser treatment may be required to seal the
leak and help the vision improve.
