Hypertelorism vs. Telecanthus — What's the Difference?

Hypertelorism is an abnormally increased distance between two organs or bodily parts, usually referring to an increased distance between the orbits (eyes), or orbital hypertelorism. In this condition the distance between the inner eye corners as well as the distance between the pupils is greater than normal.

Telecanthus, or dystopia canthorum, refers to increased distance between the inner corners of the eyelids (medial canthi), while the inter-pupillary distance is normal. This is in contrast to hypertelorism, in which the distance between the whole eyes is increased.

Abnormal distance between two paired organs, especially the eyes.

Increased distance between the medial canthi of the eyes, while the interpupillary distance is normal.
