Eye trauma vitreous opacity

Under normal circumstances, the vitreous body of our eyes appears translucent and feels like gel. Because the vitreous body of the eyes has no blood vessels and nerves, its metabolism is relatively slow. When the vitreous body of the eyes becomes cloudy, the patient will see things in a filamentous, flocculent, and cloud-like blurry state, which is also commonly known as the fly phenomenon. When this happens, you should go to the hospital for treatment in time.

What are the symptoms of vitreous opacity in the eyes?

The normal vitreous body is a transparent gel that has no blood vessels or nerve tissue. Its metabolism is extremely slow, and its nutrition and metabolism are completed through diffusion from adjacent tissues. Vitreous opacities refer to the vitreous body being dusty, filamentous, flocculent, streaky, or cloudy. It is not an independent eye disease, but one of the common clinical signs of ophthalmology and can be caused by a variety of diseases.

Generally speaking, patients with mild vitreous opacities will feel that there are black shadows floating in front of their eyes, just like a mosquito flying by. The disease occurs relatively suddenly. Although it does not affect vision, it can cause vision loss.

What are the dangers of vitreous opacity?

1. Vitreous opacities can cause vitreous hemorrhage. Repeated vitreous hemorrhage can eventually transform into a dense membrane. At the same time, new blood vessels from the retina grow into the vitreous cavity, affecting central vision. Membrane traction can cause retinal detachment and cataracts.

2. The rupture of new blood vessels causes vitreous hemorrhage again, which leads to a vicious cycle and eventually neovascular glaucoma and even eyeball atrophy. After massive vitreous hemorrhage, the aqueous humor barrier is destroyed. Degenerated red blood cells in the vitreous cavity enter the anterior chamber, blocking the chamber angle and further developing into ghost cell glaucoma.

3. Vitreous opacities are a dangerous sign before blindness. If treated promptly, the disease can be prevented from progressing and vision can be saved. For example, vitreous opacities can cause retinal detachment, but if a careful examination is performed when vitreous disease first occurs, dry holes can sometimes be found, and laser treatment can prevent retinal detachment.

Which kind of vitreous opacity should be treated promptly?

Generally speaking, vitreous opacities are not dangerous. Although they will cause some vision loss, they will not affect vision. However, there are some situations that require attention to avoid retinal detachment and affect future life.

If you just find that your vitreous body is a little cloudy, it is best to go to the hospital for a thorough check-up. Sometimes dry holes can be found. Laser treatment can avoid retinal detachment, thus avoiding the pain of surgery and greatly reducing the possibility of blindness due to retinal detachment.

It should be noted that if there is an obvious history of trauma before the onset of vitreous opacities, 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 require timely medical attention.
