What are the signs of a damaged cornea

So, that clear, dome-shaped front part of your eye? That's the cornea. Acts like a windshield and helps you focus. When it gets messed up — injury, infection, disease — you'll know. Usually right away. Catching these signs early? That's make-or-break for your vision.

What are the most common symptoms of corneal damage?

People with a damaged cornea usually feel a bunch of these symptoms. Could be just mild annoyance. Could be screaming-level pain.

• Severe eye pain: Like someone's stabbing you in the eye. Not a headache. Sharp, gritty. It's local and it's brutal.
• Blurred or hazy vision: Your cornea needs to stay crystal clear. Swelling or scarring? Everything gets foggy. Like looking through a frosted window.
• Redness of the eye: Inflammation does this. Keratitis or just the conjunctiva going nuts. Eye looks bloody or pink.
• Sensitivity to light (Photophobia): Bright lights hurt. You'll squint. Daylight becomes enemy territory.
• Excessive tearing or discharge: Eye tries to flush out junk. Sometimes you get thick yellow or green gunk if there's infection.
• Feeling of a foreign body: Like sand or an eyelash is stuck. But there's nothing there. Drives you crazy.
• Difficulty wearing contact lenses: Suddenly your comfortable lenses feel like torture. Painful, tight. Can't keep 'em in.

How can you tell the difference between a scratched cornea and a serious infection?

Both are bad. Both need a doc. But they're different. A scratch? Usually from a fingernail, a tree branch, or you messed with your contacts. An infection? That's a corneal ulcer. More dangerous. Usually builds over hours or days.

Expert Insight: "Any white spot on the cornea is a medical emergency. Do not try to remove it or treat it at home. This is a classic sign of a corneal ulcer, which can perforate the eye if not treated with prescription antibiotic drops immediately."

What does a scratched cornea feel like?

A corneal abrasion? It's specific. And intense. Patients say things like:

• Intense burning or stinging: Like acid or hot pepper juice got in there.
• Uncontrollable blinking or squinting (Blepharospasm): Your eyelid just slams shut. Involuntary. Because it hurts that bad.
• W pain with blinking: Every time that eyelid slides over the scratch? Sharp spike of pain.
• Watery eyes that don't relieve the pain: Tears don't help. Not like a dust speck. This is different.

What is the checklist for emergency eye care?

Think your cornea is damaged? Do this. Don't wait around hoping it'll get better.

• Remove contact lenses immediately. Don't throw 'em away. Put 'em in a clean case. Bring to the doc for testing.
• Do not rub the eye. Seriously. You'll turn a scratch into a disaster. Or rupture an infected ulcer.
• Do not use eye drops that claim to "get the red out." They constrict blood vessels. Mask symptoms. Bad idea.
• Do not patch the eye tightly. Warm, dark environment = infection heaven. A loose shield is fine.
• Seek same-day evaluation from an ophthalmologist or visit an emergency room. Not an optician. Not your primary care doc. This is serious.
