Central Serous Chorioretinopathy

This is a disorder in the retina, the layer of nerve cells at the back of the eye, which sense and transmit visual signals to the brain for sight.

Central serous chorioretinopathy (CSCR)is a problem affecting the macula, the central portion of the retina which is responsible for central vision or the ability to see details.

In CSCR, leakage of fluid through a break in the pigment layer of the retina results in the macula forming a ‘blister’, thus distorting vision.

The exact cause of this condition is unknown, although it is thought to be strongly linked to stress and a Type A personality. It usually occurs in the 25 to 45 year age-group, and predominantly in males.

SYMPTOMS

• Blurred central vision
• Distorted vision such as straight lines appearing wavy
• Central blind spot

DIAGNOSIS

• Ophthalmoscopy
• Fluorescein angiography

TREATMENT

There is no specific treatment for CSCR. The leak usually resolves spontaneously, with the fluid being reabsorbed over a period of weeks to months.

In some cases with delayed recovery, laser treatment or photodynamic therapy may be used to seal the leak and improve vision.

There is a 20 to 30 percent risk of recurrence, with each episode causing more damage to the retina, resulting in more permanent visual loss.
