Why carry out this study?

Foveal eversion (FE) has been recently described as a structural optical coherence tomography (OCT) parameter associated with high prevalence of macular edema and poor outcome in diabetic retinopathy.

The main hypothesis of this study is that FE might be applied also to macular edema secondary to central and branch retinal vein occlusion (CRVO and BRVO, respectively).

What was learned from the study?

The presence of FE has been associated with worse clinical course and outcome compared with eyes without FE in both CRVO and BRVO eyes.

We described three different patterns of FE, categorizing three clinically different RVO subgroups. Our findings support the role of FE as a clinically relevant and easily assessable metric to be included in the diagnostic workup of RVO.
