Cystoid macular oedema (CMO) occurs secondary after an ophthalmic disorder, trauma or rarely after an eye operation. There is a fluid which accumulates through the retinal layers, causing blurry vision and paramorphopsia of the central visual field. CMO rarely causes permanent vision loss.
Vision restoration is often a low, gradual process. The majority of patients restore their vision in 2-15 months either they are under treatment or not. In the above photograph, the oedema is represented as yellow spots (arrow) on the macula.
