Hypertelorism
Hypertelorism (pronounced: hi-per-TEL-or-izm) is a medical condition characterized by an abnormally increased distance between two organs or bodily parts, typically referring to an increased distance between the eyes. The term is derived from the Greek words "hyper" meaning over or excessive, and "telos" meaning end or purpose.
Definition
Hypertelorism is a condition where the distance between two body parts is greater than normal. In medical terms, it most commonly refers to an increased distance between the eyes (orbital hypertelorism). However, it can also refer to an increased distance between other body parts, such as the nipples (mammary hypertelorism).
Causes
Hypertelorism can be caused by a variety of genetic disorders, including Down Syndrome, Crouzon Syndrome, and Apert Syndrome. It can also be caused by certain environmental factors during pregnancy, such as exposure to certain drugs or toxins.
Symptoms
The primary symptom of Hypertelorism is an abnormally wide space between the eyes. Other symptoms can vary widely depending on the underlying cause of the condition and can include other facial abnormalities, developmental delays, and health problems related to the specific genetic disorder causing the hypertelorism.
Treatment
Treatment for Hypertelorism typically involves surgery to move the eyes closer together. This can improve appearance and may also improve vision if the hypertelorism is causing vision problems. Treatment for any underlying conditions or genetic disorders will also be necessary.
