What is vitreous opacity surgery

Vitreous opacity surgery may sound incomprehensible to normal people, and some people don’t even know what the vitreous is. In fact, the vitreous body is related to people's vision and it exists in the eyes. Once there is a problem with the vitreous body, it may cause blindness. So what is vitreous opacity surgery? Is there any knowledge of blindness in this? I will introduce it to you in detail today.

A small number of patients with vitreous opacities are important warning signs of some blinding diseases and require timely surgery to avoid the progression of the disease and save vision.

The vitreous body cannot regenerate. The vitreous body is not glass. It is a glass-like substance in the human eye. It is colorless, transparent, semi-solid, and gel-like. Its main component is water, which accounts for about 99% of the volume of the vitreous body. The vitreous body has a concave surface in front that accommodates the lens.

According to ophthalmologists, when people are young, the lens and vitreous body can adhere tightly and well. As people age, the adhesion between the lens and vitreous body gradually deteriorates, making it easy to separate them during senile cataract surgery. There are no blood vessels in the vitreous body. The nutrients it needs come from the aqueous humor and choroid. Therefore, it has a slow metabolism and cannot regenerate. If there is a defect, the space will be filled by the aqueous humor.

There are many causes of vitreous opacities with varying degrees. In most cases, vitreous opacities will not cause vision loss and may not even require treatment. For example, physiological floaters, mild senile degeneration and myopic changes.

But in a few cases, the presence of vitreous opacities is a very important warning sign of some blinding diseases. For example, retinal detachment generally requires surgical treatment, but if a careful examination is carried out in the early stages, laser treatment can be used to avoid retinal detachment and the pain of surgery can be avoided.

According to ophthalmologists, in addition to congenital vitreous opacities, bleeding or exudates from hypertension, diabetes, and uveitis invading the vitreous, and vitreous degeneration in the elderly with high myopia can all lead to vitreous liquefaction and opacity. Other reasons such as eye trauma or prolonged retention of foreign objects in the eye can also cause vitreous opacities.

When the vitreous undergoes pathological conditions such as bleeding, inflammation, degeneration, or when the position of the vitreous changes, the diseased vitreous becomes an obstacle, affecting vision, and even acts as a pathogenic factor, causing damage to adjacent eye tissues.

It should be noted that if there is an obvious history of trauma before vitreous opacities appear, there are more black shadows floating in front of the eyes, they appear faster and more suddenly, and are accompanied by flashes and decreased vision, these are often manifestations of this type of disease and you should seek medical attention promptly.

The above content is the relevant knowledge about vitreous opacity surgery that we introduced to you today.
