What is Cystoid Macula Oedema (CMO)?

Cystoid macular oedema – CMO – occurs when blood vessels in your retina leak fluid into the macula.

This can cause a build-up of fluid leading to swelling and a reduction in fine detailed vision. It can be caused by a wide range of ophthalmic conditions including after surgery and trauma.

Cystoid Macula Oedema (CMO) Diagnosis

What are the Symptoms?

  • distorted and blurred vision that makes a grid of straight lines appear wavy, blurry, or blank.
  • loss of central vision
  • difficulty reading
  • colours look washed out / different
  • seeing floaters in your vision

What are the Causes?

There is a range of factors that can contribute to the development of cystoid macular oedema and a CMO medical diagnosis, including diabetes, after-effects of eye surgery, age-related macular degeneration (AMD), blocked retinal blood vessels, inflammatory eye diseases, ageing, genetic conditions, eye tumours and eye injury. 

When discussing the symptoms with your Laser Vision specialist, we will also take any of these factors into consideration.

Cystoid Macula Oedema (CMO) Symptoms

What is the Diagnosis?

Cystoid macular oedema is initially treated with a combination of topical steroid and non-steroidal anti-inflammatory topical drops for 4-6 weeks.

If the CMO does not resolve, a short course of oral acetazolamide in combination with the above topical drops is given. If the CMO remains incalcitrant, the patient may be offered one of the following: a sub-tenon’s injection of steroid, an injection of steroid or an anti-VEGF into the posterior chamber of the eye.
