The symptoms of a corneal abrasion include:
You are more likely to have corneal erosion if you:
Corneal abrasions are also diagnosed using a special dye and light, especially in emergency departments or health care offices without access to slit-lamp biomicroscopes. After drops of fluorescein dye are inserted in the eye, the doctor shines a blue light on the eye. Any abrasions on the eye will appear green.
A diagnosis of corneal laceration by slit-lamp examination is an indication for repair. Signs and symptoms of a corneal laceration after trauma are decreased vision, ocular pain, a positive Seidel test, irregular pupil such as a peaked or teardrop pupil, intraocular foreign body, and prolapse of intraocular contents.

The procedure is simple and does not take a long time. The doctor will ask you to remove clothing from the area that will be examined. The doctor will then darken the room and hold the Wood's lamp a few inches away from your skin to examine it under the light.
Immediate steps you can take for a corneal abrasion are to:Rinse your eye with clean water or a saline solution. You can use an eyecup or a small, clean drinking glass positioned with its rim resting on the bone at the base of your eye socket. ... Blink several times. ... Pull the upper eyelid over the lower eyelid.
Feel like you have sand or grit in your eye. Have pain, especially when you open or close your eye. Notice tearing and redness. Become sensitive to light.
A combination drop of polymyxin and trimethoprim is commercially available. For large or dirty abrasions, many practitioners prescribe broad-spectrum antibiotic drops, such as trimethoprim/polymyxin B (Polytrim) or sulfacetamide sodium (Sulamyd, Bleph-10), which are inexpensive and least likely to cause complications.

A slit lamp exam can help diagnose the following conditions: macular degeneration, a chronic condition affecting the part of the eye that is responsible for central vision. detached retina, a condition when the retina, which is an important layer of tissue at the back of the eye, becomes detached from its base.
Fluorescein sodium, the sodium salt of fluorescein, is used extensively as a diagnostic tool in the field of ophthalmology and optometry, where topical fluorescein is used in the diagnosis of corneal abrasions, corneal ulcers and herpetic corneal infections.
A Wood's lamp can be used to detect bacterial or fungal skin infections. It can also be used to detect skin pigment irregularities, like white patches on your skin called vitiligo, or corneal abrasions, which are scratches on your eye. It is sometimes used to select infected skin or hair for lab tests.
When you see an eye doctor for a corneal abrasion, he or she will perform a slit lamp examination using fluorescein dye – a special drop used to identify abrasions. The doctor will also carefully examine the eye for any hidden foreign bodies and evaluate for infections.
You should not wear your contact lens until after the abrasion has completely healed. It typically takes 1-5 days for a corneal abrasion to heal. When your eye doctor examines your cornea, he or she may place a numbing drop to make the examination more comfortable.
Most corneal abrasions occur after minor trauma to the eye. Causes include a fingernail, walking into a tree branch, or contact lenses (during their placement or removal), although something as small as a grain of sand can also cause an abrasion!
The cornea is made up of 5 layers, and the epithelium is the outermost layer of the cornea that is exposed to the environment. You may think of the epithelium as equivalent to the skin on our body.
A corneal abrasion can be extremely painful! The cornea is the most densely innervated part of the human body. Just as a comparison, the cornea is about 500 times more densely innervated than the skin. That means that even a relatively small abrasion can cause significant discomfort.
Sometimes an antibiotic ointment will be prescribed (instead of or in addition to drops), which plays the additional role of providing a “soothing” surface while the abrasion heals. Every time you blink, your eyelids rub against the abrasion, and this can be quite painful.
Placing an ointment or gel onto the cornea will soften the impact of the eyelids, and make you overall more comfortable. This is similar to a scratch on the skin – any time your clothes rub against the scratch, it is painful. But an ointment or cream can lessen that pain.
Some topical medications might be used. Topical analgesics (pain relievers) are relatively common to manage any pain the eye injury causes. The necessity and effectiveness of antibiotics for corneal abrasions are sometimes questioned, but they have been shown to help prevent further complications in at least some cases.
To avoid corneal abrasions, wear protective eyewear when performing activities where debris or other materials might be at risk of hitting your eye. ( Learn More) Additionally, be sure to keep the fingernails of infants and young children short, so they do not accidentally scratch their own eyes.
Corneal abrasions represent about 8 percent of eye injuries that are serious enough for someone to seek help from a doctor. A corneal abrasion occurs when the corneal epithelium, the outermost layer of the cornea (the lens of your eye that is key to seeing), is scratched or otherwise damaged.
A severe corneal abrasion can take three days or slightly longer to heal. While it is a good idea to see a doctor for any corneal abrasion, a severe corneal abrasion could lead to permanent damage.
Corneal abrasions occur on the outermost layer (epithelium) of the cornea, called the corneal epithelium. ( Learn More) These abrasions can be quite painful, make it difficult to look at light, cause heavy tearing, and blur your vision. ( Learn More)
It used to be quite common that an eye would be patched to protect it as it healed, but this has been found to often be ineffective and even detrimental for corneal abrasions. Patches are only now prescribed for very specific purposes, such as to help keep children and people with certain mental illnesses from rubbing their injuries.
If you wear contact lenses, you should return to your doctor in 24 hours and then again after three to four days even if you feel completely well. Contact lenses can complicate eye injuries, as they rest directly on the eye. Do not rub an injured eye when it is healing.
