Where is choroid fissure located?

Where is choroid fissure located?

The choroidal fissure is located between the thalamus and fimbria; it begins at the inferior choroidal point behind the head of the hippocampus and constitutes the medial wall of the posterior two-thirds of the temporal horn 1).

How do you treat a choroidal fissure cyst?

There are limited reports about choroidal fissure cyst being treated via surgery. These usually require only follow-up. Tubbs et al.6) reported progression of choroidal fissure cysts which were treated with fenestration and possible ventriculo-peritoneal shunting.

What is fetal fissure of eye?

Introduction. The optic fissure, also termed the choroid fissure, is an embryologic structure essential for the morphogenesis of the eye. Its formation and eventual closure are implicated in the morphogenesis of the iris, ciliary body, retina, choroid, optic nerve, and central retinal artery.

Can choroid fissure cyst cause seizures?

Choroid cysts are best observed on coronal sections on neuroimaging and among the MRI sequences FLAIR is considered to be superior. These cysts can become symptomatic and cause seizures if they increase in size by compressing adjacent structures.

What causes choroid fissure cyst?

The choroidal fissure is a cleft in the medial part of the lateral ventricle between the fornix and the thalamus [3]. Developmental errors may occur at the time of formation of primitive choroid plexus anywhere along the choroid fissure, thus forming a cyst.

Is the choroid part of the retina?

A thin layer of tissue that is part of the middle layer of the wall of the eye, between the sclera (white outer layer of the eye) and the retina (the inner layer of nerve tissue at the back of the eye). The choriod is filled with blood vessels that bring oxygen and nutrients to the eye.

What does the choroidal fissure do?

The choroidal fissure (CF) is an important landmark that allows approaches to the deepest aspects of the brain. It is the C-shaped site of attachment of the choroid plexus in the lateral ventricles, which runs between fornix and thalamus.

How common is choroidal fissure cyst?

Choroidal fissure cysts are rare and often incidentally discovered [1]. There are a few cases reported and they are usually asymptomatic. The relationship between complex partial seizure and temporal fissure cyst is controversial [2].

How do fetus eyes develop?

Your baby’s eyes start out as two tiny outgrowths from the developing brain. Beginning at 6 weeks of pregnancy, these growths start to fold inward and form two cup-like structures. As these structures enlarge, they remain connected to the brain by a stalk that will eventually house the main optic nerve.

Can arachnoid cysts cause migraines?

In many cases, arachnoid cysts do not cause symptoms (asymptomatic). In cases in which symptoms occur, headaches, seizures and abnormal accumulation of excessive cerebrospinal fluid in the brain (hydrocephalus) are common.

What happens if the choroid is damaged?

Degeneration of the blood vessels of the choroid is followed by damage to the retina, which usually leads to loss of peripheral vision that can progress to eventual blindness. Central vision is usually preserved until late in life.
