Posterior vitreous detachment

What is the vitreous body?
Vitreous body is a gel located in the posterior part of the eye, in the space between the crystalline lens (which is removed in cataract surgery) and the retina (the inner layer in which the image is focused and is transferred to the brain).

The gel of the vitreous body is transparent and consists mostly of water (98%), but it also contains collagen, sugars and salt. The role of the transparency is to allow the light to reach the retina.

What is the posterior vitreous detachment?

The vitreous body of young children, as well as adolescents is compact and is strongly attached to the retina. As part of the natural aging is usual for the components of the vitreous body to degenerate. In particular the vitreous body becomes watery and is detached on its own from the retina. This condition is called posterior vitreous detachment.

Posterior vitreous detachment symptoms

Posterior vitreous detachment can cause flashing lights, which may appear at the peripheral visual field, or permanent shadows, like flies which are called floaters. This happens because these opaque parts of the vitreous body are located between the light source and the retina, causing shadows that may appear like threads, bubbles or small black spots, which follow you as you look around!

Posterior vitreous detachment diagnosis

Posterior vitreous detachment can be diagnosed through fundoscopy (dilated pupils) on the slit lamp.

Posterior vitreous detachment treatment

Posterior vitreous detachment therapy is performed only surgically by the method of vitrectomy. In vitrectomy, the cause of the detachment (the vitreous body) is removed, using small tools. In particular, the surgical procedure which is used for floaters removal is called fluotorectomy. In the majority of cases, the surgical incisions are so small that can be healed without sutures usage.

Innovative vitrectomy technique by a 27gauge diameter tool

It's about a new vitrectomy method which contains precise and delicate tools of small diameter. These small tools permit the fast healing and recovery after the surgery. It also reduces the risk of inflammation. We can have excellent by reducing the intrusive of a larger diameter tool.

Bear in mind: Posterior vitreous detachment does not cause blindness. However, in case that you notice any of the symptoms mentioned above, you should visit an ophthalmologist as soon as possible, in order to prevent the case of retinal tear or retinal detachment, as they have similar symptoms.
