Central Serous Chorioretinopathy
Central Serous Chorioretinopathy (CSCR or CSR) is a common condition that affects young people between the ages of 20-50. It is more common in males.
Fluid accumulates underneath the retina and if this occurs at the central macular it results in blurred vision. Patients usually present with central distortion or blurred vision in one eye. Colours may appear washed out and there can be a central scotoma. Symptoms are usually unilateral. Metamorphopsia and image size distortion are common. There is a 5% prevalence in Cushing’s syndrome.
What causes CSCR?
In most cases, a cause is never identified. However, stress and use of steroid medications are thought to be associated in certain cases.
How is CSCR treated?
In most cases CSCR resolves spontaneously and no treatment is required. Over 90% of patients return to normal or near normal vision within 3-4 months. Occasionally patients continue to have reduced colour vision, night vision or distortion.
Some patients with non-resolving CSCR require laser treatment after 4-6 months. Photodynamic therapy is also emerging as a possible treatment option in certain patients
Other newer treatments that can be considered for some patients include oral medications that block mineralocorticoid receptor such as Spironolactone or Eplerenone.
