RVD: Cystoid Macular Edema and Related Diseases
2 Self-Assessment AMA PRA Category 1 Credits™
Cystoid macular edema (CME) is most commonly seen after cataract surgery. It may occur with vascular disease, retinal dystrophy, uveitis, and usage of certain medications. CME arises from the accumulation of fluid within the retina when there is disruption of the normal blood-retinal barrier and abnormal permeability of the perifoveal retinal capillaries.
