Common Eye Conditions

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.
