Retinal examination: the doctor may use an instrument with a bright light and a special lens (ophthalmoscope) 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 inflammation.Previous eye surgery, such as cataract removal.A family history of retinal detachment.Previous retinal detachment in one eye.Aging - retinal detachment is more common in people over age 50.The following factors increase your risk of retinal detachment: The flashes may be more noticeable when your eyes are closed or you’re in a darkened room. You may see sudden new floaters or flashes of lights (photopsia). Left untreated, fluid from the vitreous cavity can pass through the tear into the space behind the retina, causing the retina to become detached. Eventually, the vitreous may separate from the surface of the retina - a common condition called Posterior Vitreous Detachment (PVD).Īs the vitreous separates or peels off the retina, it may tug on the retina with enough force to create a retinal tear. The areas where the retina is detached lose this blood supply and stop working, so you lose vision.Īging-related retinal tears that lead to retinal detachmentĪs you age, your vitreous may change in consistency and shrink or become more liquid. These tissues contain a layer of blood vessels called the choroid. Retinal detachment due to a tear in the retina typically develops when the vitreous collapses and tugs on the retina with enough force to create a tear.įluid inside the vitreous then finds its way through the tear and collects under the retina, peeling it away from the underlying tissues. Retinal detachment can occur when the gel-like material (vitreous) leaks through a retinal hole or tear and collects underneath the retina.Īging or retinal disorders can cause the retina to thin. A sagging vitreous which is the gel-like material that fills the inside of your eye.Retinal detachment can occur as a result of: Similar rapid loss of vision may also be caused by bleeding into the vitreous which may happened when the retina is torn. A curtain-like shadow over your visual field.Ī few detachments may occur suddenly and the patient will experience a total loss of vision in one eye.Gradually reduced side (peripheral) vision.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 include the sudden appearance of floaters and flashes and reduced vision. 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. The retina is the part of your eye that sends visual signals to the brain along the optic nerve. Retinal detachment is an emergency situation in which a thin layer of tissue (the retina) at the back of the eye pulls away from its normal position.
