Know About Corneal Ulcer : Symptoms And Prevention Procedures

SHARE

A corneal ulcer is a painful sore on the clear thin covering of the eye .
These are more likely to affect people who wear contact lenses and are often caused by infections. Having a corneal ulcer may feel like there's something in the eye and you may be more sensitive to bright light.

Left untreated, a corneal ulcer can lead to permanent vision problems. Contact lens wearers particularly are susceptible to eye irritation that can lead to a corneal ulcer. A contact lens may rub against the eye's surface, creating slight damage to the epithelium that may enable bacteria to penetrate the eye.

Some people may also develop a severe loss of vision along with visual obstruction due to scarring over the retina. Corneal ulcers can also cause permanent scarring on the eye. In rare cases, the entire eye may suffer damage.
Although corneal ulcers are treatable, and most people recover quite well after treatment, a reduction in eyesight may occur.
An optometrist or ophthalmologist will diagnose the condition based on the symptoms and an examination with a slit lamp after putting fluorescein drops in the eye. A swab sample may be taken for laboratory testing to determine the cause of the ulcer.

Prevention
◾Wear eye protection when exposed to small particles that can enter your eye.
◾If you have dry eyes or if your eyelids do not close completely, use artificial teardrops to keep your eyes lubricated.
◾If you wear contact lenses, be extremely careful about the way you clean and wear your lenses.
◾Always wash your hands before handling the lenses. Never use saliva to lubricate your lenses because your mouth contains bacteria that can harm your cornea.
◾Remove your lenses from your eyes every evening and carefully clean them. Never use tap water to clean the lenses.
◾Clean and sterilize your contacts before and after wearing them
◾Never sleep with your contact lenses in your eyes.
◾Store the lenses in disinfecting solutions overnight.


◾Remove your lenses whenever your eyes are irritated and leave them out until your eyes feel better.
