What is a corneal abrasion?
To know about the corneal abrasion, first get the details regarding the cornea. The cornea is the thin, transparent dome that covers the iris of the eye and the pupil. The iris is the coloured part of your eye and the pupil is the black centre. All the light that enters your eye and allows you to see first touches your cornea.
Dust, metal stains, grains of sand, fingernails, animal claws, or other foreign objects can scratch your cornea. Contact lenses can scratch or irritate the cornea. A small scratch is called a corneal abrasion. Most corneal abrasions are small and heal quickly.
Sometimes the friction of the cornea can cause inflammation in the eye. This is called iritis. Infected corneal abrasions can also lead to corneal ulcers. These are serious conditions that can develop from corneal abrasions.
Facts you should know about a corneal abrasion
A corneal abrasion is a painful scrape or scratch of the surface of the clear part of the eye. This clear tissue of the eye is known as the cornea, the transparent window covering the iris, the circular coloured portion of the eye. The cornea has many nerve endings just under the surface, so that any disruption of the surface may be painful. Seek medical care for sudden vision loss, severe eye pain, or an eye injury. Treatment may incorporate antibiotics, anaesthetic eye drops, and/or an eye patch.
Symptoms of corneal abrasion
Because they affect the way the cornea works, corneal friction can cause vision problems. Your child may complain of burning or perforation in the eye, an inability to see as usual, or blurred vision. If you have scratched your eye before, you will remember how it feels. If not, you can:
- Feels like sand or grit in my eye
- You have pain, especially when you open or close your eyes.
- Note the tearing and redness
- Become sensitive to light
- Vision is blurry
Corneal abrasion causes
The eye has other defences in addition to the orbital bone. The lids and eyelashes work to keep foreign cells away from the eyes. When cells enter the cornea, tears help remove them. However, sometimes a foreign object touches the cornea, scratching, cutting, or damaging the surface.
Ingredients that can damage the cornea include dust, sand, wood chips, hay, sparks, insects, pieces of paper, and nails. Corneal damage can also be caused by chemical irritations, improper use of contact lenses, reactions to bright lights, and eye makeup and contact lens solutions.
You can get a scratch if you do:
- Pierce your eye with a fingernail, a pen, or a makeup brush.
- Getting dust, sand, sawdust, ash, or other foreign matter in your eyes
- Put the chemicals in your eye
- Rub very hard
- Wear poor or dirty contact lenses
- Get a specific type of eye infection
- Performing surgery without proper eye care.
- Playing sports without safety glasses or doing high-risk physical activities
- Get over your contact lenses
- You may not feel symptoms right away. As a result, you may not be able to identify the cause.
Diagnosis of corneal abrasion
Most people know immediately when something misses them. If the eye hurts later, it could be corneal friction. Even a minor injury to the cornea can be very painful.
You can give yourself corneal friction without realizing it. This happens when you try to lift a contact lens, but the lens is not actually in the eye. Rubbing a finger directly on the cornea can cause small scratches.
Your doctor must examine the injured cornea:
- You develop blurred vision after an eye injury.
- You have new eye pain that will not resolve in minutes or hours.
- Even if he can’t find anything, he feels like there is something in his eye.
- Actually, there is dust, small particles, a crack, etc. in the eye.
- The eye is very sensitive to bright light.
Treatment of corneal abrasion
If you scratch your eye or get something in your eye, rinse it immediately with clean water or saline. You can remove sand, grit, or other foreign matter from your eye while blinking several times. Do not rub your eye, touch your eyeball, or put other solutions or ingredients in your eye.
If your healthcare provider tells you that you have corneal abrasions, they will look for signs of infection. They will also determine if you need a topical antibiotic in the form of eye drops. If your friction is severe, you can get a prescription for eye drops to relieve pain and sensitivity to light.
You can also get a prescription for pain relievers. In most cases, your cornea will heal quickly, usually within several days. Your eye can be taped shut and you should wear the patch to avoid embarrassing yourself. A small scratch should heal on its own in 1 to 3 days. More severe friction takes longer.
If your eye is healed:
- Don’t rub your eye.
- Do not wear contact lenses until your eye doctor says it is safe to do so.
- Wear sunglasses to reduce discomfort caused by sun exposure.
It should fully recover from a minor scratch without permanent damage to the eye. But deep scratches can cause infections, scars, and other problems. If you don’t take care of them, they can lead to chronic vision problems. Report any unusual symptoms to your ophthalmologist, including recurrence of pain after treatment. In cases of mild irritation, such as a piece of dust flying into your eye, you can wash the foreign object from your eye with clean tap water.
The eye can be cleaned by tilting the head back and pouring water into the open eye. You can fill a sink with water and open your eyes and submerge your head in the water. Laboratories and industrial settings where chemical contaminants are likely to be produced include eyewash stations to clean the eyes if necessary.
Artificial tears or over-the-counter lubricants can improve eye discomfort. Over-the-counter pain relievers, such as acetaminophen (Tylenol), can help. If a single dose of these medications does not give you relief, see your eye doctor.
After your eye exam, you should close your eyes and rest to help with the healing process. This means not reading. You should also not drive until your ophthalmologist tells you that it is safe to do so, as driving with a visual impairment can put you and others at risk. Instead, ask someone to guide you to your appointment with an ophthalmologist.
How to prevent corneal abrasions?
To prevent eye injuries, you must adhere to the following preventive measures:
- Wear goggles when participating in certain sports, such as racquetball.
- Wear goggles in situations where objects fly into your eyes. This may include wearing glasses or sunglasses while walking to avoid objects blown by the wind, as well as wearing goggles that provide 180-degree protection when using a grinding wheel or hammering metal. For welding, special goggles are available that must be worn at all times.
- Wear protective goggles to avoid UV radiation when exposed to strong sunlight for a long time. This is especially important when water skiing or on the beach, as reflecting sunlight from snow, water, or clear sand in combination with direct sunlight can double your sun exposure and cause sudden corneal burns.
