Can cystoid macular edema be treated so that vision returns to normal?

Treatment for cystoid macular edema is directed at the cause, and may vary from post-cataract edema (anti-inflammatories including steroid or non-steroidal anti-inflammatory eyedrops, tablets and injections around or into the eye), diabetes (injections into the eye or laser treatment to the retina), or vitreous traction (where surgery is offered).

Vision often improves significantly when the edema resolves, however you are correct in asking if it will ever return to normal. Unfortunately vision quality may never be completely normal again. Even if the visual acuity returns to 6/6, there are often minor changes in color perception, or contrast sensitivity that may be detected with fine diagnostic tests.

You should discuss your specific situation with your attending ophthalmologist.

As there are many factors that lead to cystoid macular edema (CME), treatments for it can vary.

For post-cataract edema, it can be treated with corticosteroids or other anti-inflammatory medication. It is done via injections or oral medications.

In prolonged cases of CME, Ophthalmologists may opt to inject the eyes with medication targeted to the retinal later or use a laser aimed at the retina.

In cases where the gel in your eyes (vitreous gel) pulls on the retina and leads to a CME, a surgery may be recommended.

Your vision should improve after treatment but do note that it may not return to how you were before. Contrast sensitivity or colour perception may change after the treatment.

Visit your ophthalmologist to ascertain the most suitable treatment for you.
