Blepharochalasis
It typically affects only the upper eyelids, and may be unilateral as well as bilateral.[1] Recurrent episodes of eyelid edema can be observed with spontaneous resolution.[2] Recurrent eyelid edema and inflammation are usually allergic or immune-mediated in origin.The exact etiology underlying immune system dysregulation and vascular issues causing the episodes are not yet fully understood (idiopathic).Hormonal changes are thought to contribute the blepharochalasis, which particularly occur in early adulthood (puberty).
