- Retinal Detachment. The retina is a structure at the back of the eye which is important for sight. When two layers of the retina become separated, it is known as retinal detachment (RD). It is a very serious eye condition and can cause severe visual impairment if it is not treated promptly.

Detached Retina Although there are several types of retinal detachment, the most common one starts when a tear or hole develops in the retina, and some of the gel-like substance that fills the inside of the eye (vitreous fluid) leaks through the opening.

Vitreous Detachment Defined Usually the fibers break, allowing the vitreous to separate and shrink from the retina. This is a vitreous detachment. In most cases, a vitreous detachment, also known as a posterior vitreous detachment, is not sight-threatening and requires no treatment.

Retinal Detachment Retinal detachment occurs when the retina separates from the back of your eye. This causes loss of vision that can be partial or total, depending on how much of the retina is detached. When your retina becomes detached, its cells may be seriously deprived of oxygen. Retinal detachment is a medical emergency.

Retinal Detachment Read about more causes of retinal detachment ». A retinal detachment is a separation of the retina from its attachments to the underlying tissue within the eye. Most retinal detachments are a result of a retinal break, hole, or tear.

Retinal detachment Retinal detachment is a disorder of the eye in which the retina separates from the layer underneath. Symptoms include an increase in the number of floaters, flashes of light, and worsening of the outer part of the visual field. This may be described as a curtain over part of the field of vision. In about 7% of cases both eyes are affected. Without treatment permanent loss of vision may occur. The mechanism most commonly involves a break in the retina that then allows the fluid in the eye to get

Retinal Detachment - Cause Retinal Detachment. Tears or holes in the retina. These may lead to retinal detachment by allowing fluid from the middle of the eye (vitreous gel) to collect under the retina. A common cause of retinal tears is posterior vitreous detachment (PVD).

What Are the Types of Retinal Detachment? Posterior vitreous detachment (PVD) is a common cause of retinal tears. It’s a normal part of aging that causes the vitreous gel to pull away from the retina in places. It's usually harmless and often has no symptoms. But sometimes, the gel builds up so much and pulls so hard that it tears the retina.

Retinal Detachment A retinal detachment is a separation of the retina from its attachments to the underlying tissue within the eye. Most retinal detachments are a result of a retinal break, hole, or tear. These retinal breaks may occur when the vitreous gel pulls loose or separates from its attachment to the retina, usually in the peripheral parts of the retina. The vitreous is a clear gel that fills two-thirds of the inside of the eye and occupies the space in front of the retina.

Retinal Detachment: What Is a Torn or Detached Retina? Retinal tear and retinal detachment Usually, the vitreous moves away from the retina without causing problems. But sometimes the vitreous pulls hard enough to tear the retina in one or more places. Fluid may pass through a retinal tear, lifting the retina off the back of the eye — much as wallpaper can peel off a wall. When the retina is pulled away from the back of the eye like this, it is called a retinal detachment. The retina does not work when it is detached and vision becomes blurry.

Retinal detachment These types of retinal detachments are the most common. Tractional — In this type of detachment, scar tissue on the retina’s surface contracts and causes it to separate from the RPE. This type of detachment is less common. Exudative — Retinal diseases can cause these types of detachments. Some examples are inflammatory disorders and injury/trauma to the eye.

- Retinal detachment is a condition in which the retina is no longer stretched over the inner wall of the eye. Since the retina is no longer in its place, one can say that it has “fallen” or “collapsed”.

Causes of Retinal Detachment Medical Editor: There are three main causes of retinal detachment, each with its own set of risk factors. The most common type is called a “rhegmatogenous” detachment, and is caused by a tear or hole in the retina. The retina is the thin, light-sensitive tissue that lines the back inside wall of the eye.

Retinal Detachment Rhegmatogenous retinal detachment. In this type of RD a hole or break develops in the retina. This can allow fluid from the jelly-like centre of the eye (the vitreous humour) to creep in between the two layers of the retina (the light-sensitive cell layer and the RPE). This causes these two layers to separate (detach).

Epiretinal membrane Healthgrades Editorial Staff. Posterior vitreous detachment, sometime simply called vitreous detachment, occurs when the vitreous, a gel-like substance attached to the retina in the back of the eye, shrinks and pulls away from the retina. By itself, vitreous detachment does not seriously affect your vision and usually does not require any treatment.
