- Congenital Abnormality
There is a paramedian frontal encephalocele and a soft tissue cleft that passes medial to an intact eyebrow. The frontal bone shows a paramedian bony cleft with an associated encephalocele. The olfactory groove, cribriform plate, and ethmoid sinus are all increased in transverse diameter, resulting in hypertelorism. The cleft extends medially to the undisturbed eyebrow to end in a short paramedian frontal widow's peak. The bony cleft begins in the region of the nasal bone and extends superiorly through the full height of the frontal bone. Posteriorly, the cleft extends through the cribriform plate and ethmoid sinus as far as the lesser wing and body of the sphenoid. The pterygoid processes are anatomically normal, but they are displaced laterally from the midline on the cleft side. There is orbital hypertelorism below and asymmetry of the floor of the anterior cranial fossa above.

Microphthalmia- MedGen UID:
- 10033
- •Concept ID:
- C0026010
- •
- Congenital Abnormality
Microphthalmia is an eye abnormality that arises before birth. In this condition, one or both eyeballs are abnormally small. In some affected individuals, the eyeball may appear to be completely missing; however, even in these cases some remaining eye tissue is generally present. Such severe microphthalmia should be distinguished from another condition called anophthalmia, in which no eyeball forms at all. However, the terms anophthalmia and severe microphthalmia are often used interchangeably. Microphthalmia may or may not result in significant vision loss.\n\nPeople with microphthalmia may also have a condition called coloboma. Colobomas are missing pieces of tissue in structures that form the eye. They may appear as notches or gaps in the colored part of the eye called the iris; the retina, which is the specialized light-sensitive tissue that lines the back of the eye; the blood vessel layer under the retina called the choroid; or in the optic nerves, which carry information from the eyes to the brain. Colobomas may be present in one or both eyes and, depending on their size and location, can affect a person's vision.\n\nPeople with microphthalmia may also have other eye abnormalities, including clouding of the lens of the eye (cataract) and a narrowed opening of the eye (narrowed palpebral fissure). Additionally, affected individuals may have an abnormality called microcornea, in which the clear front covering of the eye (cornea) is small and abnormally curved.\n\nBetween one-third and one-half of affected individuals have microphthalmia as part of a syndrome that affects other organs and tissues in the body. These forms of the condition are described as syndromic. When microphthalmia occurs by itself, it is described as nonsyndromic or isolated.
