9 Serious Eye Symptoms to Watch Out For
More than 250 million people are visually impaired worldwide, according to the World
Health Organization (WHO).
Of these cases, about 80 percent of them could have been avoided or cured.
That’s why regular eye exams are so important.
A checkup can be particularly helpful in detecting progressive eye conditions, such as glaucoma,
a common condition that typically has few symptoms in its early stages.
Some people may experience symptoms such as a change in vision or eye pain that require
immediate medical attention.
If you experience any of these following symptoms, see an eye doctor right away:
1.
Flashing Lights, Floaters, or a Gray Shadow in Your Vision
The sudden onset of flashing lights, a noticeable increase in the amount of floaters, a shadow
in your peripheral vision, or a gray curtain moving across your field of vision could be
signs of a detachment of the retina — the nerve layer in the back of the eye that sends
images to the brain.
Nearsightedness, eye diseases like glaucoma, and physical injury to the eye are among the
causes of retinal detachment.
Unless treated quickly, usually with surgery, retinal detachment can lead to blindness.
2.
Sudden Loss of Vision in One Eye Sudden vision loss could signal a number of
eye diseases and conditions.
One is macular degeneration, also known as age-related macular degeneration or AMD, which
is a leading cause of vision loss in people 65 and older in the United States.
Vision loss caused by AMD can be gradual, but in some cases it can be sudden — when
blood vessels in the eye leak fluid or blood under the retina, which is made up of nerve
cells that allow you to see.
Another cause of sudden vision loss could be a type of glaucoma, which leads to a rapid
buildup of fluid pressure in the eye that damages the optic nerve.
There are many other conditions that can cause persistent loss of vision.
3.
Eye Pain Most eye diseases are painless, but some conditions
or injuries can result in eye pain, says Richard Shugarman, MD, an ophthalmologist in West
Palm Beach, Florida.
Eye pain can be caused by glaucoma, dry eye, an eye injury, a scratched cornea, or even
cancer of the eye.
4.
Eye Injury Any significant injury to the eye should be
evaluated by a doctor, particularly if there is redness or pain that lasts for more than
15 to 20 minutes.
5.
Persistent Discomfort in the Eye If you experience any discomfort in your eye
after doing an activity in which a small particle could have entered your eye, such as hammering
or working under a car, don’t ignore it.
Have your eyes checked out by a doctor to make sure that you don’t have a foreign
particle in the eye, which can cause an infection.
6.
Red Eye “Having two red eyes is probably not as
serious as one red eye,” says Dr. Shurgarman.
When both eyes are red at the same time, it could be a sign of a cold or conjunctivitis
(pink eye) — minor infections that are self-healing.
But one red eye can be an indicator of a deeper inflammation, such as scleritis or uveitis.
Scleritis is the inflammation of the tough, outer protective barrier around the eye, and
uveitis is the inflammation and swelling of the middle coating of the eyeball.
7.
Eye Discomfort if You Wear Contact Lenses While most people who use contact lenses don’t
experience problems when they follow the rules of proper contact lens care and use, serious
infections can occasionally occur.
If you wear contact lenses, never ignore eye pain, redness, or discomfort — see an eye
doctor right away.
8.
Blurred Vision Even if it clears up, blurred vision can be
a sign of a number of eye problems, such as glaucoma, uveitis, a torn retina, or AMD.
Losing vision in one eye may be an early symptom of a stroke.
“Vision loss, especially in one eye, could be a sign that the carotid artery, which is
a major supplier of blood to the eyes, is blocked,” says Shugarman.
9.
Eye Surgery Complication If you’ve had eye surgery and experience
any redness, eye pain, or blurring of vision, call your doctor right away for an evaluation.
Even if a symptom appears to go away, you’re better off checking with your eye specialist
if you encounter any of these warning signs.
