A condition where a fold of skin partially covers the inner corner (canthus) of the eye. It is normal and common in infants but may give the appearance of an inward eye deviation (esotropia). In some cases, epicanthus can persist beyond infancy and be associated with craniofacial syndromes or genetic disorders. It can occur in isolation or combined with other features like increased distance between the inner canthi (telecanthus) or narrow palpebral fissures (blepharophimosis). Surgical correction may be considered if epicanthus causes functional or cosmetic concerns.
