Your cornea is the clear layer on the front of your eyeball. It protects your eyeball from dust and germs and helps filter out harmful ultraviolet, UV, rays. The cornea also helps to focus light entering your eye. Although your cornea is composed of strong proteins, it can be injured. A slight cut or scratch, abrasion, is often minor. But a bad abrasion or a puncture to the cornea can be very serious and can affect your vision. These are medical emergencies.
CORNEAL ABRASIONYour cornea is the clear layer on the front of your eyeball. It protects your eyeball from dust and germs and helps filter out harmful ultraviolet, UV, rays. The cornea also helps to focus light entering your eye. Although your cornea is composed of strong proteins, it can be injured. A slight cut or scratch, abrasion, is often minor. But a bad abrasion or a puncture to the cornea can be very serious and can affect your vision. These are medical emergencies.Causes of Corneal AbrasionSome of the main causes of a corneal abrasion are:Anything hitting or blowing into the eye, such as sawdust or sandSmall particles getting stuck under your eyelid, such as dust, dirt or sandSports injuriesContacts that are not fitted right or not maintained correctlyAn object that pokes you in the eyeRubbing the eyes too muchEye conditions, such as a bacterial infectionSymptoms of Corneal AbrasionA corneal abrasion may cause the following symptoms:Pain in the eye, which can get worse when the eye is opened or closedThe feeling that something is in your eyeRedness or tearingSensitivity to lightBlurred vision or loss of visionHeadacheTreatmentIf you think you have something small in your eye, flush it with water right away. Pull your upper lid out and over your bottom lid to help increase the flow of tears across your eye. A minor corneal abrasion will heal on its own in a few days.If these methods don’t work, call your doctor. Never try to remove an object from the eye that doesn’t flush out easily with water. Doing so may cause more damage.For Minor Abrasions:Minor abrasions are usually treated with antibiotic eye drops or ointment. You may be given antibiotics to prevent infection, or medication to reduce the pain. In some cases, you may wear a patch on your eye or sunglasses to lessen the symptoms. Most abrasions heal in a day or two. To help rule out more serious injuries, you may have one or more of the following tests:A standard eye exam checks how well you can see.A slit-beam exam uses a beam of light and a microscope to show your eye in detail.A Seidel test uses a special dye to look for severe eye damage.Depending on the results of these tests, you may be referred to an eye specialist, ophthalmologist.For Serious Abrasions or Punctures:You will be referred directly to an ophthalmologist for emergency treatment.
