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.
