A Mittendorf dot is a small, circular opacity on the posterior lens capsule, classically nasal in location, which represents the anterior attachment of the hyaloid artery. The hyaloid artery is present during gestation and typically regresses completely. Failure to do so can lead to benign findings, such as a Mittendorf dot or a Bergmeister's papilla, or pathologic changes as seen in persistent fetal vasculature syndrome.
