If a retinal tear is present, it must be treated immediately because a torn retina can quickly deteriorate into a detached retina.Ī retinal tear is generally treated by sealing the retina to the back of the eye with laser surgery or a freezing process called cryotherapy. It’s very important to see an experienced ophthalmologist such as our doctors for an evaluation if you see flashing lights, lightning streaks or a floater. A floater may be a harmless speck of tissue. Flashes and streaks may be occurring because the vitreous gel is simply rubbing against the retina and no tearing is present. However, you may experience these conditions and not have a torn retina. Floaters may mean specks of retinal tissue are floating in the vitreous gel.įlashing lights, lightning streaks and floaters are all symptoms of a torn retina. Light flashes and lightning streaks could mean retinal cells are not in their normal position to receive clear, focused visual images. When the retina comes loose, it no longer receives oxygen and nutrients from the blood vessels at the back of the eyeball, which results in permanent vision loss. However, sometimes it pulls hard enough that the fluid flows behind these tears and lifts the retina from the back of the eye. Normally there are no problems when the vitreous separates from the retina. A retinal tear occurs when the vitreous, a clear gel that fills the middle of the eye, pulls away from the retina at the back of the eye. Retinal tears and detachment may be caused by eye injury, the aging process, tumors, cataract surgery, eye disease or extreme nearsightedness. Left untreated, retinal detachment almost always causes permanent sight loss in the affected eye. When this happens, vision becomes blurred, shaded or distorted. A detached retina occurs when the retina pulls away from the inside back wall of the eye.
Tears in the retina may impair vision and lead to a detached retina. Normally, the retina lies against the back of the eye where blood vessels supply it with oxygen and nutrients. The retina is the light-sensitive tissue at the back of the eye that sends images to the brain.
