What is considered Hypertelorism?
Continuing Education Activity. Orbital hypertelorism is defined as an increased distance between the orbits, with true lateral displacement of the orbits. Hypertelorism is associated with underlying craniosynostosis syndromes, median facial clefting, and some other genetic syndromes.
How is Hypertelorism diagnosed?
Diagnosis is by both a clinical assessment of the child and imaging of the bones of the skull, most commonly a CT scan. This will allow accurate measurements of the bones that make up the orbit, and to see whether there is an ongoing cause for the hypertelorism that needs early treatment.
How is Hypotelorism measured?
Can be assessed by measuring the interocular distance/diameter (IOD) and the binocular diameter (BOD) both of which are typically reduced with hypotelorism. These are best measured in the axial plane.
What’s it called when your eyes are far apart?
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.
When babies eyes are far apart?
During development in the womb, a baby’s eyes normally start far apart and gradually move closer together. Any process that interferes with that movement results in orbital hypertelorism. Orbital hypertelorism can occur as an isolated finding with unknown cause or can be a feature of various genetic conditions.
What does it mean when a baby has wide set eyes?
In orbital hypertelorism, the eye sockets fail to rotate into their normal position, resulting in wide-set eyes with extra bone between the eyes.
What is the most common cause of Hypotelorism?
It is often a result of fetal alcohol syndrome (FAS), caused by large alcohol intake in the first month of pregnancy. It can be associated with trisomy 13, which is also known as Patau syndrome, as well as hereditary neuralgic amyotrophy. It can also be associated with fragile X syndrome and Prader–Willi syndrome.
What is normal interorbital distance?
As a rule of thumb, the interorbital distance should be roughly equal to the ocular diameter – however specific biometric charts are available. Increased interocular distance is referred to as hypertelorism and decreased distance as hypotelorism.
What do wide set eyes indicate?
Wide set eyes are identified when the distance between a child’s eyes is greater than the width of the eye from corner to corner.
What causes eyes to be too far apart?
Orbital hypertelorism is a condition in which the position of the bones around the eyes is further to the side than normal. This causes the eyes to be too far apart, grossly deforming the appearance. This can be corrected with a procedure called an orbital osteotomy.
How do I know if my baby has Noonan syndrome?
Most children with Noonan syndrome have differences in the shape of their face and head. These are noticeable at birth and include: wide-set pale blue or blue-green eyes. thick, low-set ears.
