What is the cause of hypertelorism?
Hypertelorism is not a diagnosis in itself; rather, it is a feature that can have many underlying causes, either due to a mass pushing the two orbits apart, a cleft in the bone between the eyes or as part of a syndrome.
How is ocular Hypertelorism measured?
Hypertelorism may be assessed by measuring the distance between the lateral orbital walls or the medial orbital walls. The interocular distance/diameter (IOD) and the biocular diameter (BOD) are both typically increased with hypertelorism.
Is hypertelorism genetic?
Teebi type hypertelorism is a rare genetic disease characterized by hypertelorism with facial features that can closely resemble craniofrontonasal dysplasia (see this term), such as prominent forehead, widow’s peak, heavy and broad eyebrows, long palpebral fissures, ptosis , high and broad nasal bridge, short nose, low …
What is pseudo hypertelorism?
Differential diagnosis. Telecanthus, also known as Pseudo-hypertelorism, is an entity in which the inner canthal distance is increased but the outer canthal distance and interpupillary distance are unchanged.
Can hypertelorism be treated?
For the treatment of hypertelorism there are two main operative options: The box osteotomy and the facial bipartition (also referred to as median fasciotomy).
Does hypertelorism affect vision?
In orbital hypertelorism, the eye sockets fail to rotate into their normal position, resulting in wide-set eyes with extra bone between the eyes.
Can Hypertelorism be normal?
In this condition the distance between the inner eye corners as well as the distance between the pupils is greater than normal….

How do you detect Hypertelorism?
Orbital hypertelorism is diagnosed by a thorough medical evaluation that will include a complete ophthalmology assessment as well as imaging tests such as a CT scan or MRI to confirm the diagnosis.

Why are my babies eyes 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.
How do you fix Hypertelorism?
Orbital hypertelorism can be treated surgically. For minor cases of orbital hypertelorism, your child’s surgeon may recommend an extracranial correction. In an extracranial correction, the bones of the inner portions of the nose and eye socket are brought closer together without going inside the skull.
What is the meaning ofocular hypertelorism?
ocular hypertelorism. a developmental defect involving the frontal region of the cranium, characterized by an abnormally widened bridge of the nose and increased distance between the eyes. The condition is often associated with other cranial and facial deformities and some degree of mental retardation. Also called orbital hypertelorism.
How is orbital hypertelorism diagnosed?
Orbital hypertelorism is diagnosed by a thorough medical evaluation that will include a complete ophthalmology assessment as well as imaging tests such as a CT scan or MRI to confirm the diagnosis.
Which anthropometric measurements are characteristic of orbital hypertelorism?
Anthropometric measurements will yield increased inner canthal distance (ICD), increased outer canthal distance (OCD), and increased interpupillary distance (IPD). Increases in all three measurements above the 95th percentile on normative anthropometric values are observed in true orbital hypertelorism.
What are the different types of hypertelorism surgery?
Surgery for hypertelorism involves two main techniques, box osteotomy and facial bipartition, both of which involve separating one part of the skull containing the orbit from another part of the skull, moving it into a position in which the eyes are closer together and securing it in place in the new position.
