- What is retinal detachment? Retinal detachment occurs when the light-sensing layer inside your eye, the retina, detaches from the underlying pigmented tissue layer that provides it oxygen and nutrients. Retinal detachment can happen spontaneously with no obvious or underlying cause.

- Trauma to the face or head or an eye injury may cause retinal detachment. Diabetes and uveitis, an inflammatory disease of the inner eye, also contribute to the development of retinal detachment. Several other risk factors can predispose you to retinal detachment.

- In a study of more than 1,500 LASIK patients, just four suffered retinal detachment; their pre-LASIK prescriptions ranged from -8.00 D to -27.50 D. Cataract surgery, tumors, eye disease and systemic diseases such as diabetes and sickle cell disease also may cause retinal detachments.

- Retinal Tear. A tear in the retina can occur with vitreous detachment (see discussion above), with trauma or eye injury, or in areas at risk for a retinal tear, such as lattice degeneration. The symptoms of a retinal tear usually are of a flash of light in the peripheral vision followed by floaters.

- Most retinal detachments happen because a tear or hole in the retina allows fluid to leak between the retinal layers and this then causes the retina to detach. Holes in the retina can occur because of changes that happen as you age, whereas tears happen because the retina has been pulled and torn.

Causes of Retinal tear Retinal tear as a complication of other conditions: Other conditions that might have Retinal tear as a complication may, potentially, be an underlying cause of Retinal tear. Our database lists the following as having Retinal tear as a complication of that condition: 1  Posterior vitreous detachment. 2  Retinopathy. 3  Vitreous detachment.

Retinal Tear And Detachment A retinal tear occurs when the tissue tears, allowing fluid to leak out. A retinal detachment occurs when the retina separates from the choroid, cutting off the blood supply to the retina. This usually develops after a retinal tear has already occurred.lthough it sounds painful, there is actually no discomfort or pain associated with retinal tears and detachments. However, there are several signs that may signal a tear or detachment has occurred or is about to occur: 1  Floaters in your line of sight.

Retinal detachment The retina is the light-sensitive layer of tissue that lines the inside of the eye and sends visual messages through the optic nerve to the brain. When the retina detaches, it lifts or pulls from its normal position. If not promptly treated, retinal detachment can cause permanent vision loss and will need surgery.

Floater and Flash Remedies A detached retina is a tear or dislocation of the eye’s back layer of light-sensitive cells and nerve endings. This can be caused by a severe blow, but it is more commonly the result of a shrinking of the vitreous inside the eyeball, which may occur with aging. Severe shortsightedness is a risk factor, as is diabetes.

Overview Retinal detachment can occur as a result of: A sagging vitreous (VIT-ree-us) — the gel-like material that fills the inside of your eye; Injury; Advanced diabetes; How retinal detachment occurs. Retinal detachment can occur when the gel-like material (vitreous) leaks through a retinal hole or tear and collects underneath the retina.

Scleral buckling You have an increased risk of retinal detachment if you: 1  are very short sighted (more than minus 6.00 D). 2  have had trauma (injury or blow) directly to the eye. 3  have already had a detachment in one eye, then there is an increased likelihood of a detachment in the other eye. 4  have a family history of retinal detachment.

Retinal detachment 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 - Symptoms Most cases of retinal detachment begin with a retinal tear. A retinal tear or another eye problem may cause: Floaters in your field of vision. Floaters are thick strands or clumps of solid vitreous gel that develop as the gel ages and breaks down. Floaters often appear as dark specks, globs, strings, or dots.

Retinal pigment epithelial detachment. Detachment of the retinal pigment epithelium may or may not be associated with choroidal neovascularization and may be caused by different types of pathogenesis, each associated with distinct angiographic features, natural course, visual prognosis, and response to treatment.

Retinal Detachments & Tears Typically, retinal detachments occur in individuals over the age of 50, although blunt trauma or being nearsighted can cause a detachment in a younger individual. Other risk factors include diabetes, rubbing the eyes or recent cataract surgery.

Retinal Detachment - Symptoms If you have new or sudden flashes or floaters, darkness over part of your visual field, or a new loss of vision that does not go away, call your eye doctor or regular doctor right away. Floaters and flashes may be warning signs of retinal detachment. Floaters are thick strands or clumps of solid vitreous gel that develop as the gel ages and breaks down. 2  Floaters often appear as dark specks, globs, strings, or dots. 3  Floaters may also be caused by loose blood or pigment from tears in the retina. 4  Flashes of light or sparks when you move your eyes or head.

Retinal Detachment: Torn or Detached Retina Causes Retinal Detachment: Torn or Detached Retina Causes. Written by: Kierstan Boyd. Reviewed by: Raj K Maturi MD. Mar. 01, 2016. Vitreous gel, the clear material that fills the eyeball, is attached to the retina in the back of the eye. As we get older, the vitreous may change shape, pulling away from the retina. If the vitreous pulls a piece of the retina with it, it causes a retinal tear. Once a retinal tear occurs, vitreous fluid may seep through and lift the retina off the back wall of the eye, causing the retina to detach or pull away. Vitreous gel, the clear material that fills the eyeball, is attached to the retina in the back of the eye.

Overview Eventually, the vitreous may separate from the surface of the retina — a common condition called posterior vitreous detachment (PVD). As the vitreous separates or peels off the retina, it may tug on the retina with enough force to create a retinal tear. Left untreated, fluid from the vitreous cavity can pass through the tear into the space behind the retina, causing the retina to become detached. PVD can cause visual symptoms.

Posterior Vitreous Detachment - Topic Overview The tear then allows fluid to collect under the retina and may lead to a retinal detachment. In addition to normal, age-related changes in the vitreous gel, PVD can also result from eye injury or inflammation or can happen after eye surgery. This kind of PVD may occur suddenly and may also cause a retinal tear.The main symptoms of PVD are floaters and flashes of light.Having floaters or flashes does not always mean that you are about to have a retinal detachment, but it is important to tell your doctor about these symptoms right away. A sudden change in these symptoms could be a warning sign of a retinal tear or detachment.he tear then allows fluid to collect under the retina and may lead to a retinal detachment.

Can eye strain cause retinal detachment? Yes, it is possible for you to get retinal detachment from eye strain because of the damages of the eyes nerves. There are many long term side effects of eye strain. Your eyes will be so dry because of eye strain. What's worse, your vision will be affected. You may have the blurry vision.

Retinal Detachment An injury to the eye or face can cause a detached retina, as can very high levels of nearsightedness. Extremely nearsighted people have longer eyeballs with thinner retinas that are more prone to detaching.
