Cystoid macular edema (CME) is a disorder affecting the retina, when there are multiple, fluid-filled, cyst-like structures in the macula (the central part of the retina that is responsible for central vision). These cyst-like structures (cystoids) cause swelling, or edema, of the macula.

Symptoms of CME

  • Blurred or distorted central vision (most common)
  • Pink-tinted or dim vision
  • Sensitivity to light

Peripheral vision is not affected by CME. It is also possible for CME to be present when there has been no vision loss. Your doctor can determine whether you have CME or not during a medical eye exam. For more information about CME, please click here.
