Corneal Abrasion
Corneal Abrasion Causes
There are a number of possible causes of corneal abrasion such as injury to the eye, and abrasive particles have entered the eyes. Excessive rubbing of the eyes can also cause abrasion and can irritate the eyes. Wearing contact lenses longer than the recommended duration can injure the surface of the eye as well as exposure to ultraviolet lights.
Corneal Abrasion Definition
A corneal abrasion is characterized by a very painful scratch or scrape on the surface of the cornea. This is the transparent window covering the iris, which is the circular colored portion of the eye. Since the cornea has nerve endings just below the surface, even the slightest damage on the surface can be very painful.
Corneal Abrasion Diagnosis
An eye examination is the most common way to diagnose corneal abrasions and to rule out other possible eye problems such as glaucoma.
Corneal Abrasion Symptoms and Signs
For people who have sustained an eye injury, a corneal abrasion is very likely. Symptoms include feeling there is a foreign object in the eye, tearing of the eye, distorted or blurred vision, eye pain especially when exposed to lights, and spasms that causes the person to squint.
Corneal Abrasion Treatment
The treatment approach for corneal abrasion is largely based on the diagnosis. Among the most common treatments include antibiotic treatments and ointments to reduce the inflammation. Pain pills and anesthetic may also be administered to manage the pain.
