You should see an ophthalmologist right away if you suddenly develop new floaters. When the vitreous gel inside your eye rubs or pulls on the retina, you may see what looks like flashing lights or lightening streaks. You may have experienced this sensation if you have ever been hit in the eye and see "stars.
These flashes of light can appear off and on for several weeks or months. As we grow older, it is more common to experience flashes. If you notice the sudden appearance of flashes, you should visit your ophthalmologist immediately because it could mean that the retina has been torn. Floaters and flashes become more common as we grow older.
While not all floaters and flashes are serious, you should always have a medical eye examination by an ophthalmologist to make sure there has been no damage to your retina. Floaters can be caused by normal aging of the eye when the vitreous jelly begins to shrink.
Other causes of floaters include the sudden release of blood cells from the retinal blood vessels or pigmented cells from underneath the retina into the vitreous jelly. This can occur with the tearing of the retina. A retinal tear can lead to a retinal detachment, which requires surgery to prevent vision loss or further vision loss. Risk factors for a retinal tear include age and having myopia nearsightedness.
Retinal tears and retinal detachment also can lead to seeing flashes of light in the peripheral vision. You may experience flashes of light and eye floaters at the same time.
Eye floaters are specks or blobs that appear and seem to move around in your field of vision. Floaters are caused by shadows cast by clumps of collagen that float in the vitreous gel-like substance in your eyeball. They are a common symptom of certain eye problems and may occur along with flashes of light. Common causes of eye floaters and flashes of light are: PVD, a retinal tear and retinal detachment. To find the cause of flashing lights in the eyes, an eye doctor may conduct a comprehensive eye exam , including ophthalmoscopy also called fundoscopy or a fundoscopic exam.
The doctor will examine the back of the eyes with a special light to check for retinal tears, detachment and other issues. Your eyes may need to be dilated with eye drops for this exam.
Remember, seeing flashing lights in your eyes could indicate a detached retina or other serious problem in the eye and you should visit your eye doctor without delay. Occasionally you noticed something flickering on the side of your vision. It is becoming more and more annoying as it starts to affect your concentration and sometimes, vision.
Most of our patients describe these flashes like a bright camera flash when the photographer is taking a photo of you. Others also describe this phenomenon as a thunderbolt on a dark stormy day that only lasts a few seconds, but it frequently occurs throughout the day.
The vitreous gives the eyeball its shape like air in your tyres. The vitreous of the eye is attached to the retina. As time goes by, the vitreous would eventually detach from the retinal interface.
When this happens, the collagen fibres, which makes up the vitreous, starts to condense or clump together. These clumps then float within the rest of the vitreous, casting a shadow on the retina.
As it floats around, the shadow follows, and the patient sees this as a dark spot wandering within their vision. There might be a small degree of cellular debris within the vitreous, causing these dark spots.
Sudden head movements can cause flashing lights, often associated with extreme sports such as bungy jumping and skydiving. Patients involved in motor vehicle accidents such as whiplash injuries can cause the vitreous to detach prematurely, causing flashes and floaters.
In either scenario, if you experience these flashes or floaters, it is essential to have your symptoms evaluated by your optometrist promptly. When you first experience these flashes and floaters, a prompt appointment to see your eye care professional is paramount.
Preparing for the holidays? Floater is a catchall term for the specks, threads, or cobweb-like images that occasionally drift across the line of vision. Flashes are sparks or strands of light that flicker across the visual field.
Both are usually harmless. But they can be a warning sign of trouble in the eye, especially when they suddenly appear or become more plentiful. A floater is a tiny cluster of cells or fleck of protein lodged in the vitreous humor. This clear, stable gel, which looks like raw egg white, supports and fills the rear two-thirds of the eyeball see "The inside story".
The vitreous provides a pathway for light coming into the eye through the lens. The vitreous connects to the retina, the patch of light-sensitive cells along the back of the eye that captures images and sends them to the brain via the optic nerve. Floaters move as your eyes move. They appear to zoom away when you try to look directly at them, and drift slowly when your eyes stop moving.
The vitreous slowly shrinks with age, causing it to become a bit stringy. The strands cast shadows on the retina, causing floaters. About one-quarter of people have some vitreous shrinkage with floaters by their 60s; that rises to about two-thirds of year-olds. Floaters also appear more often in people who are nearsighted, those who have had cataract surgery or a previous eye injury, and those with diabetes.
Although most people tolerate floaters just fine, others feel that floaters affect their vision and disrupt their ability to read. Flashes occur when the vitreous gel bumps, rubs, or tugs against the retina.
Like floaters, flashes are generally harmless and require no treatment. The shrinking vitreous can tug on the retina and pull away from it. In about one in six people, a posterior vitreous detachment causes the retina to tear. Fluid from inside the eye can then seep through the tear and separate the retina from the tissues that nourish it.
This separation, called retinal detachment, can lead to permanent vision loss. The ophthalmologist uses a laser to make a series of tiny burns around the retinal tear.
