Why does a retinal tear




















Retinal holes are typically smaller and have a lower risk for causing a retinal detachment. There are some instances where retinal holes should be treated the same as retinal tears. Risk factors are not required to develop a retinal tear, but they make the likelihood greater. These factors include:.

In cases where there is a limited view of the retina due to overlying hemorrhage, ophthalmic ultrasound may be required to aid in diagnosing a retinal tear.

If a retinal tear is diagnosed promptly before it progresses to retinal detachment, the prognosis is extremely good. Retinal tears are typically treated with laser or a freezing procedure cryotherapy.

Treatment is performed in an office setting and is very effective and quite safe. Topical or local anesthesia is utilized, and the procedure is only mildly uncomfortable. The treatment creates spot-welding around the edges of the tear that nearly eliminates the risk of the tear progressing to retinal detachment.

After a tear has been treated, there remains a future risk of developing additional, separate retinal tears; therefore, continued monitoring is important. Not all retinal tears require treatment.

A retinal tear can lead to fluid and blood collecting in the eye, which can cause the development of several new floaters and loss of vision if the tear leads to a retinal detachment. The retina plays a vital role in vision.

Damage to the retina can cause vision loss and even permanent blindness. The retina is the thin layer of tissue that lines the back of the eye on the inside. The retina processes light through light-sensitive cells called photoreceptor cells. These cells are responsible for detecting light stimuli, which in turn get interpreted as images.

The photoreceptor cells pass the information on to the optic nerve, which sends visual information to the brain. One condition that can stop this communication between the retina and the brain is a retinal detachment, which can result from a retinal tear. The most common symptoms of a retinal tear include flashes of light in the eye and visible spots called floaters. Retinal tears can develop and progress quickly, which may lead to retinal detachment. Other symptoms to watch out for include:. In some cases, however, a retinal tear may not cause any noticeable symptoms.

A retinal detachment is a medical emergency. If you notice any symptoms of retinal tear and you start to lose vision, call your eye doctor immediately. A delay in treatment could worsen your outcome. In most cases, a retinal tear occurs when the vitreous gel inside the eye contracts and tears the retina away from the eye wall.

The main function of vitreous gel is to help the eyeball hold its spherical shape during fetal eye development. There is still a lot to learn about the function of the gel. After the eye develops in utero, the purpose of the vitreous gel is unknown.

This gel also helps the retina hold its place against the interior wall of the eyeball. The contraction of the vitreous gel can occur slowly over time or suddenly after experiencing a trauma to the eye. Other conditions associated with retinal tears include:. At around the age of 60, the vitreous gel naturally begins to separate from the back of the eye.

This normal occurrence, known as posterior vitreous detachment PVD , is part of the normal aging process. Your healthcare provider will need to perform a thorough comprehensive eye examination. This is called posterior vitreous detachment PVD. It's not clear exactly why PVD can lead to retinal detachment in some people and there's nothing you can do to prevent it.

But it's more likely to happen if you:. You can get a detached retina more than once. Get medical help as soon as possible if the symptoms come back. Page last reviewed: 16 December Next review due: 16 December Detached retina retinal detachment. Urgent advice: Get advice from now if:.
