![]() The bubble applies gentle pressure, helping a detached section of the retina to reattach to the eyeball. TreatmentĪfter sealing a retinal tear with cryopexy, a gas bubble is injected into the vitreous. Also, if you experience new symptoms, it's important to return to your doctor right away. If a tear is not identified at this visit, your doctor may ask you to return within a few weeks to confirm that your eye has not developed a delayed tear as a result of the same vitreous separation. Your doctor will likely examine both eyes even if you have symptoms in just one. Your doctor may use this test if bleeding has occurred in the eye, making it difficult to see your retina. This type of device provides a highly detailed view of your whole eye, allowing the doctor to see any retinal holes, tears or detachments. The doctor may use an instrument with a bright light and special lenses to examine the back of your eye, including the retina. Your doctor may use the following tests, instruments and procedures to diagnose retinal detachment: Previous other eye disease or disorder, including retinoschisis, uveitis or thinning of the peripheral retina (lattice degeneration).Previous eye surgery, such as cataract removal.Aging - retinal detachment is more common in people over age 50.The following factors increase your risk of retinal detachment: Exudative detachment can be caused by age-related macular degeneration, injury to the eye, tumors or inflammatory disorders. ![]() In this type of detachment, fluid accumulates beneath the retina, but there are no holes or tears in the retina. Tractional detachment is typically seen in people who have poorly controlled diabetes or other conditions. This type of detachment can occur when scar tissue grows on the retina's surface, causing the retina to pull away from the back of the eye. Left untreated, the liquid vitreous can pass through the tear into the space behind the retina, causing the retina to become detached. One complication of this separation is a tear.Īs the vitreous separates or peels off the retina, it may tug on the retina with enough force to create a retinal tear. Normally, the vitreous separates from the surface of the retina without any complications - a common condition called posterior vitreous detachment (PVD). As you age, the gel-like material that fills the inside of your eye, known as the vitreous (VIT-ree-us), may change in consistency and shrink or become more liquid. The most common cause of rhegmatogenous detachment is aging. The areas where the retina detaches lose their blood supply and stop working, causing you to lose vision. This fluid builds up and causes the retina to pull away from underlying tissues. Rhegmatogenous detachments are caused by a hole or tear in the retina that allows fluid to pass through and collect underneath the retina. These types of retinal detachments are the most common. There are three different types of retinal detachment: Retinal detachment is a medical emergency in which you can permanently lose your vision. Seek immediate medical attention if you are experiencing the signs or symptoms of retinal detachment. A curtain-like shadow over your field of vision.Gradually reduced side (peripheral) vision.Flashes of light in one or both eyes (photopsia).The sudden appearance of many floaters - tiny specks that seem to drift through your field of vision.But warning signs almost always appear before it occurs or has advanced, such as: Contacting an eye specialist (ophthalmologist) right away can help save your vision. Warning signs of retinal detachment may include one or all of the following: reduced vision and the sudden appearance of floaters and flashes of light. The longer retinal detachment goes untreated, the greater your risk of permanent vision loss in the affected eye. Retinal detachment separates the retinal cells from the layer of blood vessels that provides oxygen and nourishment to the eye. Retinal detachment describes an emergency situation in which a thin layer of tissue (the retina) at the back of the eye pulls away from its normal position. Retinal detachment is often accompanied by flashes and floaters in your vision. Retinal detachment describes an emergency situation in which a thin layer of tissue (the retina) at the back of the eye pulls away from the layer of blood vessels that provides it with oxygen and nutrients.
