What is a choroid crack?

choroids are an optical component that participates in the early fetal development. This tubular structure acts as a transit route for optical nerves leaving the eyes and enters the blood vessels. Correct choroid crack combines during development. The inability of the fuse can cause a hole called colloboma, inside the eye.

The eye begins to develop for about four weeks to develop the fetus. This begins when embryonic cells create two niches in the front brain. The expansion of the growth of these niches causes slim structures to call optical stems. Optical stems connect niches - later called optical vesicles and then optical cups - with the brain wall and eventually become an optical nerve.

It runs under optical stems is a clutch. The continuous crack contains a hyroid artery and a hyroid vein. The blood vessels of the nutrients pass through these structures into the formation lens. When the fisure fuses were closed, the vein and the artery were trapped inside the optical stems. Then develop into the retinal heart rateny and veins.

The visual system is created rapidly during embryonic development. The sixth week of pregnancy should be melted with a choroid. This process occurs very quickly, so it is necessary for each part of the process to work properly. When the crack with the choroid does not disintegrate, colloboma is formed.

Colobomas may appear in one or both eyes. The severity of the loss of vision depends on the size of the colloquil and its location. Coloboma iridis, the most common form, affects the iris of the eye. This simpler defect results in less loss of visual axis than other colloboms. With this form, light sensitivity can be increased.

Coloboma can also form in the fundus of the eye. Fundus contains optical components that include the retina, macula, optical disk, and a layer of blood vessels and taps the choroid. If the choroid crack is usually closed, then the wheels are on the front of the fundusOboma and causes less problems than an alternative. A more open crack of choroids will expand the collobol back to the fundus and cause problems with central vision.

Problems with associated eye, such as microftalmos or insufficiently developing eyeballs, may worsen this loss of vision. There is no medicine for colobomas. Young children can be monitored by a specialist in seeing to diagnose and monitor the condition of the condition.
